Opis:
Detection and classification of vegetation is a crucial technical task in the management of natural resources since vegetation serves as a foundation for all living things and has a significant impact on climate change such as impacting terrestrial carbon dioxide (CO2). Traditional approaches for acquiring vegetation covers such as field surveys, map interpretation, collateral and data analysis are ineffective as they are time consuming and expensive. In this paper vegetation regions are automatically detected by applying simple but effective vegetation indices Normalized Difference Vegetation Index (NDVI) and Soil Adjusted Vegetation Index (SAVI) on red(R) and near infrared (NIR) bands of Landsat-8 satellite image. Remote sensing technology makes it possible to analyze vegetation cover across wide areas in a cost-effective manner. Using remotely sensed images, the mapping of vegetation requires a number of factors, techniques, and methodologies. The rapid improvement of remote sensing technologies broadens possi-bilities for image sources making remotely sensed images more accessible. The dataset used in this paper is the R and NIR bands of Level-1 Tier 1 Landsat-8 optical remote sensing image acquired on 6th September 2013, is processed and made available to users on 2nd May 2017. The pre-processing involving sub-setting operation is performed using the ERDAS Imagine tool on R and NIR bands of Landsat-8 image. The NDVI and SAVI are utilized to extract vegetation features automatically by using python language. Finally by establishing a threshold, vegetation cover of the research area is detected and then classified.

Results of many years research of geo-botanic of the Kurile Islands are presented in article. Vegetation spatial structure of the Kurile Islands is conditioned by complex interactions of endogenous and exogenous factors. Meridional extension for almost 1200 km determines a significant climatic differenciation within archipelago. It is resulted in changes of vertical vegetation zones in the different regions of Kurile Islands. System of hot and cold currents in the adjacent sea water is the factor of asymmetry of vegetation. Special traits of archipelago are determined by the volcanic activity

Application of laser scanning data in the analysis of the changes in vegetation vertical structure and changes in a semi-natural section of the Vistula valleyChanges in vegetation cover are one of the features affecting the functioning of river valleys. Vegetation influences the geomorphological and hydrological processes within a water basin. Controlling the quality and quantity of vegetation is crucial for keeping the eco- and geosystem balance. Until now the methods applied in controlling vegetation were not efficient (field work) or were not providing enough information about the vertical structure of plant communities (i.e. analyses based on data obtained from optical remote sensing do not allow precise determination of vegetation height). The aim of this study was to determine the changes in the extent and vertical structure of the vegetation within a semi-natural section of the Vistula river valley in Krakow between 2006 and 2012 using airborne laser scanning. The application of such data in this type of research was also evaluated. The study revealed that, in spite of spite of maintenance work, the extent of vegetation cover increased during the monitoring period. Data verification indicated high precision and suitability of these data in the determination of the vegetation cover changes at the local scale. A wider access to data obtained from airborne laser scanning should soon result in the proliferation of studies conducted using airborne laser scanning which will positively impact the cost and quality of such research.

Opis:
The influence of some ecological factors to aquatic and marsh vegetation was studied during 1998-2000. Three basic vegetation units (Caricetum buekii, Typhetum latifoliae and Ceratophylletum submersi) and three transitional communities were defined in the belt transect, which was established along the moisture gradient. The content of available soil nutrients in individual vegetation types differed only in case of the Ceratophyllum submersum community, where a higher magnesium and nitrogen content accumulated due to specific environmental conditions. Water and marsh vegetation is usually characterised by a pronounced spatial and temporal dynamics. In the studied area, its zonation was dependent from the terrain morphology, and both depth and duration of floods. The fluctuation of ground and surface water table during a three-year period caused changes in the occurrence and cover of several species (e.g. Carex buekii, Typha latifolia, aquatic macrophytes). Pronounced changes in the cover of some species occurred even within a single vegetation season due to the long-term sink of water table below the ground surface.

The phytosociological database Polish Vegetation Database collects relevés of all vegetation types in Poland. The database was established in 2007 and is located at Department of Biodiversity and Plant Cover Protection, University of Wrocław (http://synbiot.uni.wroc.pl). On March 2012, the database included 40000 relevés collected between 1927 and 2011. Most of relevés was taken from published papers and represents almost all types of habitats of Poland. Large groups of relevés represent meadows and pastures (Molinio-Arrhnehteretrea), broadleaf forests (Querco-Fagetea), arable land communities (Stellarietea), coniferous forests (Vaccinio-Piceetea) and eutrophic reed communities (Phragmitetea). In comparison to other countries in Central Europe, Polish Vegetation Database currently belongs to medium-sized databases, with full functionality and accessibility. The present article describes its development, basic operational information and how it can be used in analysis of vegetation in Poland.

Opis:
The problem of slope stability is one of the most difficult issues, which constitutes the object of interest of engineering geology and geotechnics. The impact of vegetation, well developed bush root system in particular, on the improvement of slope and escarpment stability, is one of the often-omitted aspects in engineering practice. Vegetation may perform a double function within a geological medium: - strengthening – by means of soil reinforcement and anchoring, binding of grains, which improves strength parameters, reduction of pore pressure and groundwater table by means of water interception; - weakening – by means of the impact of specific gravity of vegetation on the subsoil, the impact of wind on a tree, which may lead to its inclination and creation of voids in the soil, moisture changes leading to shrinkage and loosening of the ground (Najder 2003, Greenwood et. al. 2004). Plant roots demonstrate much tensile strength. They increase the ground’s cohesion owing to their friction and adhesive properties. Changes of these parameters depend on the spatial reach and the type of root system. The following types may be distinguished: intensive (concentrated) and extensive (diffused) (Reubens et al. 2007). A given root type impact zone depends on the location of the potential slip surface and the kind of mass movement (Koda et al. 2010). A landslide in Pietrzejowice, located on the Proszowice Plateau, at a distance of approximately 25 km from Cracow, is the object of the research (Kondracki 2010). Landslide movement was initiated on 14 May 2010. At night on 3–4 June further development of the landslide occurred, leading to the damage of two residential buildings. Surface deformations occurred in the area of approximately 3 ha. A geological medium was subdivided into five geotechnical layers: silty clay with different consistency and Miocene clay (Jaskólski et al. 2012). Numerical analyses of the slope stability were carried out in the FLAC 7.0 programme, whose computational algorithm is based on the finite difference method. Two options of the root system development – concentrated and diffused – were adopted in the model. Numerical simulations were carried out as per the scheme (Pilecki et al. 2014): 1) Static analysis of the data set for variable soil and water conditions with Duncan and Wright method (Kaczmarek & Popielski 2015). 2) Elaboration of the set of input data. 3) Elaboration of the physical model. 4) Elaboration of design model along with adopted initial and design conditions. The following options were considered: - variant I – natural slope condition, - variant II – condition after water accumulation, variant III – development of concentrated root system, - variant IV – development of diffused root system, - variant V – water accumulation of option III, - variant VI – water accumulation of option IV. 5) Calculation of the results and their verification. 6) Analysis of the probability of occurrence of mass movements for the adopted design options. Statistical analysis of the set of input data and results of numerical simulations allowed determining the impact of the root system on changes of the safety factor with the soil variable and water conditions. The route of the slide surface and determination of the probability of the loss of stability, with local or global nature, are also important pieces of information. The results of numerical simulations indicate an increased value of safety factor for the slope with extensive root system. The results are of a reconnaissance nature and they describe the impact of the root system on stability in a general manner.

Opis:
Vegetation mapping is an active research area in the domain of remote sensing. This study proposes a methodology for the mapping of vegetation by integrating several vegetation indices along with original spectral bands. The Land Use Land Cover classification was performed by two powerful Machine Learning techniques, namely Random Forest and AdaBoost. The Random Forest algorithm works on the concept of building multiple decision trees for the final prediction. The other Machine Learning technique selected for the classification is AdaBoost (adaptive boosting), converts a set of weak learners into strong learners. Here, multispectral satellite data of Dehradun, India, was utilised. The results demonstrate an increase of 3.87% and 4.32% after inclusion of selected vegetation indices by Random Forest and AdaBoost respectively. An Overall Accuracy (OA) of 91.23% (kappa value of 0.89) and 88.59% (kappa value of 0.86) was obtained by means of the Random Forest and AdaBoost classifiers respectively. Although Random Forest achieved greater OA as compared to AdaBoost, interestingly AdaBoost provided better class-specific accuracy for the Shrubland class compared to Random Forest. Furthermore, this study also evaluated the importance of each individual feature used in the classification. Results demonstrated that the NDRE, GNDVI, and RTVIcore vegetation indices, and spectral bands (NIR, and Red-Edge), obtained higher importance scores.

Monitoring the agricultural drought of paddy rice fields is a crucial aspect of preparing for proper action in maintaining food security in Indonesia. The Aceh Province is one of Indonesia’s national rice production centers, especially Aceh Besar Regency; it includes three central districts; Indrapuri, Kuta Cot Glie, and Seulimeum. Satellite-Sentinel 2A data have been tested to monitor the drought levels of around 2,803 Ha in the three districts in this study. This study aimed to determine the drought level in Indrapuri, Kuta Cot Glie, and Seulimeum districts, Aceh Besar Regency’s paddy rice fields using Sentinel-2A data imagery. The vegetation conditions index (VCI) of Sentinel-2 data was utilized to identify a vegetative drought level in the area for the 2018, 2019, 2020, 2021, and 2022 growing seasons. The vegetation inertia index is derived from the Normalized Difference Vegetation Index (NDVI). The results show that the VCI looked volatile, but the trendline increased by four percent, from 92.56 in July 2019 to 96.08 in July 2021. Most areas on the dates investigated found that the no drought category was still dominant. The designated data analyzed found that the June 2022 data tend to be distributed to the drought in extreme, severe, moderate, and mild increases compared to the previous data investigated. This figure shows an increasing drought in the study area, and the average drought index is in the category of mild drought. In addition, there has been a trendline decline in the value of NDVI in recent years, causing agricultural land for paddy rice fields to be slightly vulnerable to drought.

Opis:
The paper presents results of the studies conducted to determine causes and directions of transformations in vegetation of meadow-pasture communities in the area of the Wielki Łęg Obrzański [Great Obra Floodmeadows]. Multifaceted natural and habitat analyses were conducted on over 1800 relevés prepared in the vegetation seasons of 2005–2009 according to Braun-Blanquet. On their basis the phytosociological and floristic structure was analysed and habitat conditions were determined by phytoindication. Moreover, laboratory methods were applied in soil analyses to determine contents of basic macro- and microelements and groundwater table levels were recorded. Results referred to the documentation and archive literature made it possible to determine causes of transformations in plant communities in that area and outline probable directions in which succession was progressing. A lack of regular land use patterns is seen as the primary cause for the transformation in the flora of the Wielki Łęg Obrzański, particularly in the last 20 years. A considerable limitation of land use in certain sections of this area has led to the initiation of dominance of nitrophilic species such as Urtica dioica, Cirsium arvense, Potentilla anserina or Galium mollugo, while in the thinned sward it led to the development of grass species with very limited economic importance. Another equally important factor affecting the structure of vegetation cover is connected with air and water relations in soils, determined by the drainage system operating there for the last 200 years and by precipitation.

Information about vegetation condition is needed for the effective management of natural resources and the estimation of the effectiveness of nature conservation. The aim of the study was to analyse the condition of non-forest mountain communities: synanthropic communities and natural grasslands. UNESCO’s M&B Karkonosze Transboundary Biosphere Reserve was selected as the research area. The analysis was based on 40 field test polygons and APEX hyperspectral images. The field measurements allowed the collection of biophysical parameters - Leaf Area Index (LAI), fraction of Absorbed Photosynthetically Active Radiation (fAPAR) and chlorophyll content - which were correlated with vegetation indices calculated using the APEX images. Correlations were observed between the vegetation indices (general condition, plant structure) and total area of leaves (LAI), as well as fraction of Absorbed Photosynthetically Active Radiation (fAPAR). The outcomes show that the non-forest communities in the Karkonosze are in good condition, with the synanthropic communities characterised by better condition compared to the natural communities.

Opis:
Methane is the second most important man-made greenhouse gas after carbon dioxide. For more than the last 20 years the increase of the rate of CH4 emission has been varying dramatically each year. This trend is common worldwide, though in different parts of the world unevenly intense, conditioned by the amount of emissions from natural and anthropogenic sources. Peatland ecosystems are one of the natural methane emitters, responsible for about 24% of the total CH4 emissions. Methane emission from wetlands is the balance between the processes of methanogenesis and methanotrophy with an active role of wetlands plants composition. Participation of vegetation in the reduction the emissions by 30-35% was confirmed. Association of methanotrophic bacteria with plants has been already recognized by Raghoebarsing and colleagues, who showed that methanotrophic bacteria, as endosymbionts and epibionts, live both inside and outside the cells of Sphagnum sp. The main aim of this study was to estimate methane emissions from Moszne peatland, dominated by: Sphagnum sp., Eriophorum vaginatum, Carex nigra and Vaccinium uliginosum.

Opis:
The effect of instream vegetation growth has largely been ignored by hydrological and geomorphological research in river environments, which focused instead on the function of riparian vegetation as a regulator of bank stability or as a buffer for dissolved and particulate matter entering the channel from the hillside. However, in many lowland streams, instream vegetation can be very intensive, resulting in high biomass levels during the growing season. Instream plants have a significant influence on the dynamics of flow, sediment, and nutrients. Plant growth can cause increased frictional resistance to flow and can have a short-to medium-term effects on the geomorphology of the channel. Additionally, plant development influences the velocity of river flow, affects sedimentation dynamics and increases flood risk. To achieve a balance between flooding and ecological management of rivers in the presence of vegetation, a reliable method is required to predict the resistance of channels. In the current study, a two-dimensional hydrodynamic and morphodynamic model is developed and applied using a new scaling expression of shear stress based on vegetation characteristics. These first attempts at field simulations showed qualitatively acceptable results and demonstrated the effectiveness of the model in predicting hydraulic parameters in the presence of vegetation. This model is useful in predicting the effect of vegetation on stream flow and river morphology, as well as in managing flood hazards and stream ecology.

The aim of my study was to determine changes in the seed bank and vegetation during the process of overgro-wing of the xerothermic grassland situated on the slopes of the White Mountain (349 m a. s. l., the Central Roztocze Region, South-Eastern Poland). I also examined whether the changes of vegetation can be predicted if we know the structure of the burned seed flora. To achieve this goal I used two sets of data: one collected from three different environments (grassland, brushwood and woodland) at the same time (toposequence), and the other collected twice from the same place at the interval of seven years (chronosequence). I stated that the appearance of even a small number of ornitochorous seeds and their seedlings can be treated as a signal that the bush encroachment will accelerate. Seed number seems to decrease during succession in the analysed sequence of plant communities. The total number of species in the seed bank did not change in the most dynamic plant communities: grassland and brushwood, and it was significantly higher there than in the seed bank of woodland. During the time of observation, the most important quantitative and qualitative changes took place in grassland vegetation, which is more similar to brushwood vegetation now than it was at the beginning of the study.

The study aimed at evaluation of the current state and description of changes in plant communities in wetland habitats in the Czarna river valley and at recommendation of ef-fective methods for the renewal of vegetation on the basis of detail analysis of its space-time changes. The methods applied included a compilation of field studies (inventory, cartographic study and phytosociological analyses), valorisation of nature, numerical syntaxonomy with the use of MVSP program (Cluster Analysis and PCA) and digital methods GIS (Geomedia Professional 6.1). The field study of the vegetation cover of the Czarna river valley was performed in the years 2010–2011. The space-time analysis of changes in the vegetation cover and renewal of vegetation was made with the use of archive aerial photographs from 1966, topographic maps from 1982 and 2000 and orthophotomaps from 2011. The vegetation cover of the Czarna river valley was found to be composed of 12 plant communities representing 6 syntaxonomic classes, and to in-clude sites of 8 protected species. The space-time analysis of the vegetation cover of the Czarna river valley, taking into account the changes in the forms of the valley use over the period 1966–2011, showed that the area occupied by forest communities in wetland habitats as a result of secondary succession has increased by 0.16 km2, so by 27% with respect to the area of 0.4406 km2 from 1966. Chronological changes in the vegetation cover over this area analysed on the basis of GIS and digital methods indicate that in the wet meadows in the valley studied the secondary succession leads to the reproduction of the potential forest communities that were growing there once in the past. The renewal of forestless greeneries in the Czarna river valley is related to changes in the use of the area realised by mowing and restoration of the earlier hydrological regime in the entire catchment area, changed by the network of channels and drainage ditches.

Opis:
Predomination of sandy bedload is typical of the anastomosing channels of the Narew River. Several types of in-channel accretionary macroforms have been found in these channels: side bars, concave-bank bars, plug bars, point bars, linguoid bars, and mid-channel bars. The first three types are relatively rare, point bars occur only exceptionally, while linguoid bars and mid-channel bars are quite common. The bars usually occur in main channels, which are the master routes of sand transport in the whole anastomosing system of the Narew. The lower parts of the bars are built of coarse- and medium-grained sand, similarly to the sediments in the deeper parts of the channels. Fine-grained sand, locally alternating with organic-rich muddy sand, predominates usually in the upper parts; peat with high content of sand is present in the highest parts of some bars. All bars are rapidly colonised and stabilised by plants. It is for this reason and due to the low energy of the river that the bar sediments have a high preservation potential. The development of bars is usually not accompanied by lateral migration of channels. Consequently, sediment accretion in bars is one of the factors leading to gradual narrowing of channels. Deposits of some sand-bars, when preserved in fossil record, may probably be represented by characteristic "wings" in the outer parts of ribbon-like sand bodies.

From the investigation at 2009, Soil fill approach can protect the original place of gully erosion well, but this apporach ignores the whole impact at the catchment scale, and may cause to new gully appear. "Vegetation cover" approach is better to control gully erosion than "Soil fill" approach, but has little effect on controlling the headcut retreat.

Opis:
The vegetation of the Chernihiv city sands (natural and technogenic origin) has rather high syntaxonomic diversity (17 associations and 5 initial communities) and the ruderal phytocoenoses prevail. Natural phytocenoses are represented to a small extent (Cyperetum flavescentis Koch 1926, Dichostylidi–Helochloetum alopecuroidis (Timar 1950) Pietsch 1973, Artemisia scoparia–Dianthus borbasii community, Kochietum arenariae Fijalk 1978). Synanthropic psammophytes species communities that are more resistant to anthropogenic influence, are formed under urban conditions. The ecological range of vegetation of sandy alluvia varies from xerophytic phytocoenoses in mineral-poor sand (Kochietum arenariae) to the communities, which indicate waterlogged areas with increased mineralization of water and saline bottom sediments (Typhetum laxmannii Nedulcu 1968). Itispossibletoobserve the adventization and apophization of sand vegetation, one of the indicators of which is the rupture of coenotic connections between the species of the community. These phenomena indicate that the process of synanthropization of the vegetation cover of the city keeps intensifying, and first of all, occurs in places of newly formed technogenic ecotopes.

Palaeobotanical (mainly palynological) data from 38 sections of Lithuania and adjacent areas were used in order to resolve some palaeogeographical problems. The Butënai Interglacial (Holsteinian) had one distinct climatic optimum, represented by the B2–B4 pollen zones. This was a period of warm and wet climate with notable mild winters. The average annual temperature might have been 2–4ºC warmer and the annual precipitation some 300 mm greater than at present in Lithuania. There was probably no permanent snow cover during winters. Isopollen maps for the main forest constituents allow deduction of the directions of migration of individual tree taxa.

Opis:
Flood plains are a specific sedimentary environment. They are a natural clarifier and filter for rivers carrying large amounts of heavy metals, biogenic elements and other contaminants transported during high water and floods. Plenty of it is accumulated in the riverbank zone of channels i.e. a buffer strip. This is a relatively narrow strip of land situated along watercourses, often covered with riparian plants. It is functionally associated with river flooding and it forms a transition zone to ecosystems of mixed (oak-lime-hornbeam) forest plants. These plants unquestionably grow into a natural protective system of surface waters against contamination flowing down from areas used for agricultural purposes. Buffer zones provide the opportunity for self-cleaning, and according researchers they are among the most efficient natural tools to protect a catchment area. They can reduce the amount of sediments and nutrients carried by surface water flowing down from agricultural areas. Besides positive effects, the zones are accompanied by the phenomenon of flow blockage, which is particularly hazardous in case of directing great water away from its main channel. Shrubby vegetation retains small elements of plant origin and thus the free flow of water stopped. The article analyses the effect of vegetation structure density on flow conditions for small plant debris on a laboratory scale.

Drought is a natural phenomenon as it often occurs in the area of Yasothon province, northeastern of Thailand. It causes effects on vegetation condition in the area. Drought information might be useful for local government to prepare for prevention and mitigation plan in the future. For this reason, the primary objective of the research was to conduct the examination of this province to find severe drought years. Firstly, the researcher needed to find Normalized Differences Vegetation Index (NDVI) and Vegetation Condition Index (VCI) by analyzing monthly Landsat data acquired at different periods of time from January to December 2014, 2015, and 2016, covering 4,096 km2. Then, the researcher needed to find relationship between VCI and monthly rainfall represented in term of space and time. As results, VCI and its relationship with monthly rainfall were congruent. VCI showed that the drought area was 33.87% or 1,387.32 km2 of studied area in 2014, 16.24% or 665.19 km2 of studied area in 2015 and 27.95% or 1,144.83 km2 of studied area in 2016. Therefore, the most and the least severe drought years were 2014, 2016, and 2015 respectively.

The paper presents the species of grasses sown in 2003, their sward participation then and the flrist status in 2015. Phytosociological records were taken using the Braun-Blanquet’s method, distinguished plant communities, the syngenesis of the recognized phytocoenoses was defied. The results allowed to determine the advantage of the ruderal synanthropic communities: Artemisio-Tanacetetum vulgaris Br-Bl. 1931 corr. 1949 (in L-2), Leonuro Ballotetum nigrae (in L-3), a community with Rubus caesius (in L-4) over the natural auxochoric Calamagrostietum epigeji Juraszek 1928 (in L-1). Their current state is referred to as a hull form. However, due to the presence of the expansive species characteristic of the above-mentioned communities, continued development can be expected towards fully developed phytocoenoses. The thesis founded about the inflence of the neighboring forest communities on the species composition of the vegetation of the subject has not been confimed. There were only three forest and scrub species with a negligible sward participation.

Opis:
Monitoring the plant moisture has a significant role in geographical research. It may be used, among the others, for climate modelling, agricultural predicting, rational water management, drought monitoring and determining vulnerability to the occurrence of the fire. Traditional methods, based on field measurements, are the most accurate, but also time-consuming. Therefore these methods can be applied only in a limited area. In order to explore bigger areas remote sensing methods are useful. To analyse plant condition and water content vegetation indices can be used. Their calculations are based on the reflectance in different bands. Despite many studies conducted on the development of remote sensing indices, still there is a need for verification of their accuracy and usefulness by comparing the results obtained through remote sensing tools with the results of field measurements. In this paper three indices are used: Moisture Stress Index (MSI), Normalized Difference Infrared Index (NDII) and transformation Tasseled Cap (the Wetness band). The aim of this study was to compare the value of vegetation indices calculated using images from Landsat 5 Thematic Mapper with the results of field measurement from five test areas of different type of land cover: cereal crops, non-cereal crops, forests, meadows and pastures. Research was carried out in province Ontario (Canada) and consisted of two stages. The first stage was the fi eld measurements, where the specified number of plant samples was collected and water content was calculated. The second stage consisted of the preparation of relevant satellite images (atmospheric correction and making the mosaic) and the calculation of vegetation indices. The study has shown, that statistical relationships between data sets obtained through remote sensing indices and calculated on the basis of field measurements are diverse for different indices. MSI and NDII values are significantly correlated with the water content in plants (R= -0.62 and 0.56, respectively). The correlation of TCW was rated as moderate (R=0.30). Spatial distribution of water content based on maps created using NDII and MSI is similar. It was noticed that TC Wetness transformation overestimates water content in cereal plants (smaller water content) and underestimates it in natural green plant ecosystems, which generally have higher water content. As a result, the range of water content values obtained from TCW is more narrow (dominates the class of 60-70% water in plants) than the range of values calculated using NDII and MSI. Both indices have more uniform distribution dominated by the classes of moderate water content (50-60%), rather wet plants (60-70%) and very wet plants (70-80%). Each index is characterized by different distribution of the water content. In general values calculated on the basis of NDII and MSI are higher than calculated using TCW. In order to perform more accurate analysis between values calculated using satellite images and the results of field measurements, the values of particular types of land cover should be compared.

The negative impact of global and regional climate changes upon the crop yields leads to the violation of the crop production stability. The development of reliable methods for assessment of the climatic factors by the reaction of the crops to them in order to minimize the impact of climatic stresses upon the sustainability of food systems is an urgent scientific task. This problem was studied on the example of growing corn. A mathematical analysis of the main meteorological indicators for 16 years of research has been performed on the basis of which the frequency and direction of the occurrence of atypical and extreme weather conditions in various periods of the corn vegetation season were established by the coefficient of significance of deviations of the weather elements from the average long-term norm. It has been proved that the probability of occurrence of such weather conditions in the period from April to September is 38–81% in terms of the average temperature of the month, and 31–69% in terms of precipitation. By using the information base of the corn yields in a stationary field experiment with the gradations of factors: A (the fertilizer option) – A1-A12, B (the crop care method) – B1-B3, C (the hybrid) – C1-C7, the most critical month of the corn ontogeny was established when the weather has a decisive influence upon the formation of the crop. With the help of the correlation-regression analysis it was proved that the corn yield most significantly depends on the average monthly temperature in June, and for the hybrids with FАО 200–299 – on the amount of precipitation in the month of May. The obtained mathematical models make it possible to predict the yield of corn at a high level of reliability depending on the indicators of the main climate-forming factors in June, that is, even before the flowering of the plants (before the stage of ВВСН 61).

Opis:
Digital elevation models (DEM), including the Shuttle Radar Topography Mission (SRTM), are used in many branches of geoscience as an ultimate dataset representing our planet’s surface, making it possible to investigate processes that are shaping our world. The SRTM model exhibits elevation bias or systematic error over forests and vegetated areas due to the microwaves’ peculiar properties that penetrate the vegetation layer to a certain depth. Numerous investigations identified that the penetration depth depends on the forest density and height. In this contribution, two methods are proposed to remove the impact of the vegetation impenetrability effect. The first method is founded on the multiple regression of two forest characteristics, namely forest height and forest density. The second method uses a lookup table approach. The lookup table and the multiple regression explanatory variables are taken from the freely available datasets, including the forest density data (MODIS_VCF) and global tree height map (GTHM). An important role in this research is played by the Ice, Clouds, and Land Elevation Satellite (ICESat) data. The accuracy tests indicate that the first method eliminates approximately 68% of the elevation bias, while the second method appears to be more effective, leading to almost complete removal of the vegetation bias from the SRTM data. The methods are fine-tuned to the local coniferous forests in Poland. Additional studies are required to finetune the methods for the leaf-off state of deciduous forests. However, a new set of parameters for both methods can be quickly developed for different locations and forest types. Both methods’ functionality and effectiveness can be improved once more accurate forest tree height and vegetation density data become available. These methods are universal in mitigating the vegetation bias from the Synthetic Aperture Radar Interferometry (InSAR) derived model and photogrammetric models.

Opis:
This study provides original data on the impact of human activity on vegetation under the specific conditions of the Kastanozem from the Kostanay region (northern Kazakhstan). Radical changes in land use are provoking deposition in vegetation. The question remains whether natural vegetation will return or whether a different type of vegetation will be created under the specific conditions of the Kastanozems soils. The evaluation of vegetation took place in the fields that were abandoned in different time horizons. Height, cover, biomass weight and species composition of vegetation were monitored. The vegetation of abandoned fields is characterized by low species diversity. Succession runs from annual species to a stage where perennial dicotyledonous species with a deep root system dominate. Spontaneous vegetation leaves a sufficient amount of biomass on the soil surface, which assumes that the land will be protected from undesirable phenomena such as erosion and desertification processes.

Monitoring of trees in urban areas can be conducted using remote sensing, but should be supported by field measurements. The article aims to present the research method used to evaluate discolouration and defoliation of trees and tree damage in the city of Białystok in Poland. The analyses were done using AISA hyperspectral images. Field measurements encompassed determining the locations, species and levels of discolouration and defoliation of trees. Remote sensing indices of vegetation were calculated and correlated with the field-measured values of discolouration and defoliation. Based on that, values of discolouration and defoliation were calculated and evaluated against the field studies. The RMSE of the acquired data was around 16%. Using parameter values, a map of tree damage was drawn up. Based on the analysis, it can be stated that a significant number of trees is undamaged, although a large portion of the trees falls into the warning class.

Opis:
In the southern Kiskunság the natural vegetation (sand steppe, fen meadow, fen or marsh and alkali vegetation) survived in the dune slack meadows (DSM). The vegetation of these meadows are species rich, and has high natural value. The main goal of this study is to reveal the hydrological backgrounds in order to help conservation of the natural values. Two DSM was investigated (MM and CS site): vegetation was sampled, observation wells were planted, and data of other wells in similar position were used to describe the hydrological background of the vegetation. The characteristic groundwater level of the same vegetation type in the relatively wet 2005 year was higher in MM site, than in the CS site. We suppose, that this is a consequence of the earlier vegetation change because of the strong decrease of groundwater level in the region of MM site. The model of hydraulic fl ow system showed that the DSMs are situated in hydraulic discharge zones. We suppose, that an upward fl ow plays an important role in development of alkali vegetation in the CS site. Cross-correlation coeffi cient between groundwater and previous precipitation indicated a quick infi ltration of rainwater into the soil, and a pressure front of the groundwater stream reaching the area of well after 22–23 days after rainfall. The quick and strong regional hydrological changes, especially the decrease of groundwater level would endanger this valuable vegetation, but certain resistance and plasticity of it is rather possible.
W południowej części obszaru Kiskunság roślinność naturalna (stepu piaszczystego, łąk bagiennych, torfowisk niskich lub mokradeł mineralnych oraz roślinność alkaliczna) zachowała się na łąkach w obniżeniach międzywydmowych (dune slack meadows DSM). Roślinność tych łąk charakteryzuje się dużą bioróżnorodnością oraz wysokimi wartościami przyrodniczymi. Głównym celem poniższego opracowania jest poznanie i określenie warunków hydrologicznych, tak aby wspomóc działania służące ochronie wartości przyrodniczych na tym obszarze. Badania terenowe przeprowadzono na dwóch obszarach łąk obniżeń międzywydmowych (obszary oznaczone MM i CS). Zakres badań obejmował określenie składu gatunkowego roślinności, instalacje studni (piezometrów) wód gruntowych. Dodatkowo wykorzystano dane z istniejących studni wód gruntowych, zlokalizowanych w analogicznych warunkach, w celu określenia tła hydrologicznego dla znajdującej się na tych obszarach roślinności. Charakterystyczne wartości położenia zwierciadła wód gruntowych dla tych samych typów roślinności w 2005 roku, który był stosunkowo wilgotny, były wyższe w przypadku obszaru MM niż dla obszaru CS. Przypuszczalnie jest to wynikiem wcześniejszych zmian roślinności spowodowanych wyraźnym spadkiem położenia zwierciadła wód gruntowych w regionie, w którym znajduje się obszar MM. Analiza wyników modelu hydraulicznego sytemu wód gruntowych wskazuje, iż obydwa obszary badawcze znajdują się strefach drenażu wód gruntowych. Sądzimy, że taki wznoszący ruch wody odgrywa istotną rolę w rozwoju roślinności alkalicznej w obszarze CS. Współczynnik korelacji pomiędzy stanami wód gruntowych a opadami poprzedzającymi wskazuje na szybką infi ltrację wód opadowych w głąb profi lu glebowego, oraz na docieranie wód opadowych na obszar lokalizacji studni wód gruntowych po okresie 22–23 dni od chwili wystąpienia opadu. Szybkie i wyraźne regionalne zmiany hydrologiczne, a w szczególności spadek położenia zwierciadła wód gruntowych, mogą stanowić zagrożenie dla wartościowych typów roślinności na tym obszarze. Jednakże, występująca tutaj roślinność charakteryzuje się również pewnym potencjałem odporności i przystosowania się do ewentualnych zmian o takim charakterze.

Opis:
Noise measurements have been carried out at eleven different sites located in three prominent cities of the Tarai region of India to evaluate the effectiveness of vegetation belts in reducing traffic noise along the roadsides. Attenuation per doubling of distance has been computed for each site and excess attenuation at different 1/3 octave frequencies has been estimated. The average excess attenuation is found to be approximately 15 dB over the low frequencies (200 Hz to 500 Hz) and between 15 dB to 20 dB over the high frequencies (8 kHz to 12.5 kHz). Over the critical middle frequencies (1-4 kHz), the average excess attenuation (between 10-15 dB) though not as high, is still significant, with a number of sites showing an excess attenuation of 15 dB or more at 1 kHz. The results indicate that sufficiently dense vegetation belts along the roadsides may prove as effective noise barriers and significant attenuation may be achieved over the critical middle frequencies (1-4 kHz).

Opis:
The purpose of this paper was to determine long-range and spatial variability of the start and end dates of a period of intense vegetation in Poland in 1966–2015. The article is based on average monthly air temperature values acquired for 20 Polish stations for 1966–2015, made available by the Institute of Meteorology and Water Management – the National Research Institute. Based on the obtained data, the dates of the beginning and end of the intense vegetation period were determined. In this study, the intense vegetation period was defined as one with an average daily air temperature ≥10°C. The mathematical formulas proposed by Gumiński (1948) were used to determine the dates of the beginning and end of the period. A period of intense vegetation in Poland in the years 1966–2015 has extended. The dates of the beginning of the period of intense vegetation changed in the latitudinal system from the south to the north while the intensity of changes in the date of the beginning in the studied area was characterized by longitudinal distribution – the most prominent in the west of Poland. The end of the intense vegetation period occurs earliest in the north-east of Poland, and latest in the west and the south. The end date changes were less significant than the start date changes. The length of the intense vegetation period ranges from the north-east to the south-west of Poland, and the most dramatic changes occurred in the west and the south-east of Poland.

Сучасний урбаністичний розвиток, надто в українських реаліях, навряд можна назвати контрольованим. Місцями хижацька, нераціональна та некомфортна забудова – дамоклів меч не тільки історичної забудови, а й екологічних проблем. Території заповідників є гарантовано захищені державою від будь-якого свавілля забудовників. Митрополичий сад Національного заповідника „Києво-Печерська лавра” як яскравий приклад комплексного вивчення та збереження – основа сталого розвитку міського середовища. Ця локація протягом десятків років є об’єктом багатовекторного дослідження. Археологічне вивчення цієї території розпочалося в середині минулого століття і, з певними перервами, продовжується до сьогодні. За цей час тут виявлено і повністю або частково досліджено низку різних за типом та хронологією археологічних пам’яток, комплекс яких доволі точно віддзеркалює основні етапи історичного розвитку зазначеної території та епохальні зміни в характері її використання. У результаті багаторічних досліджень тут розкрито понад 700 м2 і встановлено наявність чотирьох основних культурно-хронологічних горизонтів, а саме: пам’яток ранньозалізного віку (VI-V ст. до н.е.), періоду Київської Русі (XI-XIII ст.), Русько-Литовського періоду (XIV-XVI ст.), доби Модерну та Нового часу. Завдяки археологічним дослідженням ми отримали дані про первинний рельєф території Митрополичого саду та змогли виділити два періоди природно-антропогенного розвитку цієї локації. Паралельно з археологічним вивченням проходили історичні студії Архімандричого саду з його трансформацією в Митрополичий, визначалися особливості його планувальної структури. У статті представлені реконструкції всіх типів флори, які могли рости у Печерському монастирі, починаючи з періоду Київської Русі, та дослідження рослинності вже існуючого саду з XVII ст. до наших днів. Сьогодні розглядається ідея створення Археологічного парку на території Митрополичого саду Національного заповідника „Києво-Печерська лавра”.
Modern urban development in Ukraine can hardly be called controlled. Irrational, uncomfortable and even aggressive housing development poses a threat to historic buildings and urban ecology. The territories of the national preserves are legally protected from any arbitrary actions of developers. The Metropolitan Garden of the “Kyiv-Pechersk Lavra” National Reserve may serve as a striking example of a comprehensive study and a basis for sustainable development of the urban environment. For decades, this location has been the subject of interdisciplinary research. An archaeological study in this area began in the 1950s and, intermittently, has been continued. During that time, many archaeological monuments of different types and from different historical periods have been discovered. Some of them are researched more than others, but together they mirror the main stages of the Metropolitan Garden’s historical development and reflect the changes in the way it has been used. As a result of many years of research, more than 700 square meters have been surveyed; they can be divided into four main cultural and chronological layers: 1) the Early Iron Age (6th-5th centuries BC), 2) the period of Kievan Rus’ (9th-13th centuries), 3) the Russo-Lithuanian period of the 14th-16th centuries, 4) modern times (17th-19th centuries). The archaeological research has resulted in data on the Metropolitan Garden’s primary relief and identification of two periods of natural and anthropogenic development of the location. This was accompanied by an archaeological study, historical studies of the Archimandrit’s Garden and its transformation into the Metropolitan Garden as well as the peculiarities of its planning structure. The article also presents reconstructions of all the types of the flora that could have grown in the Pechersk Monastery since Kievan Rus’ and a the study of the vegetation of the existing garden since the 17th century. Today the authorities are considering creation of an Archaeological Park within the Metropolitan Garden of the National Reserve “Kiev-Pechersk Lavra”.

Opis:
Alluvial soils, which are found under the grasslands in the study area, are formed by erosive and sedimentation activity of waters from surface and river flows. These waters in river valleys, depending on the activity duration, flow speed and the frequency of overflows, determine the spatial distribution of sediments, the variability of their mechanical composition, as well as the layers thickness, the content of organic matter and the diversity of the lay of alluvial material areas. The mentioned factors have significant influence on the structure of soil profile and on the elements circulation in the trophic chain: soil – water – plant – animal – human. The aim of the study was the typological identification of soils in the floodplain of the Warta estuary valley, as well as the characterization of their basic physical and chemical features, with the special consideration to contamination with heavy metals. Moreover, the chemical content of the plant communities in the study area was described. The studies were conducted in the Warta valley on the passage between Świerkocin and Kłopotowo, on grasslands which are part of the right flood terrace of the valley, between the water surface and the levee (floodbank). Objects of varied habitat conditions and vegetation were isolated on the chosen area for the specific research .The characterization of soil conditions was performed according to the methods commonly used in pedology. Based on the description of morphological features of soil pits, the following subtypes of alluvial soils were distinguished: heavy humus, medium brown, actual medium, actual very light. Shaped plant communities were qualified to the following floristic types: Glyceria maxima, Phalaris arundinacea, Poa trivialis, Poa pratensis, Festuca rubra and Corynephorus cannescens. The analyzed soils were evaluated as rich in general forms: P, K, Mg, Ca, Na i S. Compacted soils were usually rich in absorbable phosphorus, the content of absorbable magnesium was from very low to high, while in very light soils the content of phosphorus and magnesium was law. Regardless of the soil type, the content of absorbable potassium found in all soil samples was very low. The analyzed soils had the natural content of heavy metals (Cd, Co, Cu, Ni, Pb, Zn, Mn, Fe), only in surface layer of heavy humus alluvial soil high contamination with cadmium and raised contamination with zinc were found. Varied content of macroelements was found in the grassland sward of the individual study points. The richest in P, K, Mg, Ca and Na was the community of rough bluegrass (Poa trivialis), located on river actual medium alluvial soil in the vicinity of embankment and subject to the constant flooding of Warta. The poorest in the analyzed heavy metals were the communities of Poa pratensis and Festuca rubra with Corynephorus cannescens on actual very light alluvial soil. Only in case of lead, high content in the sward of Phalaris arundinacea formed on actual medium alluvial soil near the water surface was found. As regards other heavy metals there was no excess of their content in the grassland sward of the studied area.

Opis:
Aeolian landscapes are typical of the area of Prebaikalye and Transbaikalye. They occur both on the shore of Baikal and at various distances from the lake and they are related to areas of boreal forest and steppe. They are characterized by both natural and anthropogenic origin. The former are more typical of Transbaikalye, where they represent old dune forms at different stages of formation, stabilized by pine forest vegetation. These landscapes probably originated at the end of the Pleistocene and the beginning of the Holocene. Anthropogenic aeolian landscapes are more clearly visible and noticeable because of the geomorphologic processes occurring there at present. They occur in both of the regions and they are related to diverse economic activities of man in the past hundred, up to two hundred, years. The dominating type of surface features is that of wind erosion, which is related to old forms being blown away. The accumulative effect of wind is definitely of minor significance there; this can be seen in minor size and diversity of forms. Vegetation, which is clearly psammophylous, adapts itself to these contemporary aeolian processes. This is mostly herbaceous vegetation, or less often shrubs or undershrub. It creates a range of plant communities and associations, frequently of unique nature and with peculiar features of adaptation of plants to life in heavy habitat conditions.

Opis:
Active surface reflectance in a UV/VIS/NIR range deserve special attention among remote sensing techniques due to the potential of information it carries. Data are diversified in terms of spatial, spectral and temporal resolution, resulting in differences in data comparison and collection of material that may be redundant. The aim of the study was to assess whether the use of high-resolution data in analysis of an intensively used meadow is justified. 116 images from Planet sensor were analysed, registered from 2016 to 2019. NDVI, EVI and GLI were calculated for all of the terms. Resampling of data was carried out, with the use of 30 m grid, prepared on the basis of 3 m Planet pixel. Data with different resolution was compared. Seasonal course of values was similar in all cases, values of chosen deciles were nearly the same, however, differences in minimum and maximum values were noted.  It was concluded that the use of high-resolution data is not advisable in the context of the spatial variability of seasonal vegetation indices in the case of a terrain with homogeneous land cover. Values of structurally simplified indices are less homogeneous than that of indicators consisting of a greater number of modifying factors.

Opis:
Recent researches have determined that vegetation is one of the essential factors for game habitat quality. Vegetation is important in the form of the following components: as a food supplier, as a shelter provider, as the creator and regulator of the micro-climate of the habitat, etc. Past practice has shown that the classical methods for evaluating habitat factors involve a lot of subjectivity and often lead to an unrealistic estimate of hunting ground capacity that can affect sustainable game management. Instead of the classical analyses, paper proposes assessment of this factor using Geographic Information System (GIS). NDVI – normalized difference vegetation index is a graphical indicator that can be used to analyze images obtained by remote sensing and is used for these purposes. The researched area was hunting ground "Kapetanski rit" – Kanjiža, Serbia. In order to assess the vegetation factor, the analysis of satellite images is done for two periods of the year (May and December/January). In May the game prepares shelters for bringing an offspring and the period December/January is taken as part of the year when vegetation coverage is minimal due to winter and game is in need of additional food and shelter. Based on the results and maps, the user of the hunting ground can have a clearer view of the vegetation types and distribution, hence assistance in planning and analyzing the territorial distribution of the game. Comparing classical methods for evaluating vegetation and the use of GIS for this purpose shows the advantages of new improved GIS methodology.

The Atriplex littoralis L. is a rare and endangered species in Poland and many other countries in Europe. In Poland it is mainly found on the west coast and also rarely in central parts. It has been seen in Puck Bay and the Gulf of Gdańsk as well as in Hel Peninsula. The grassleaf orache is a halophyte, terophyte and a sunlight-loving plant. Data shows that apart from on the coast, this species may also appear in inland areas, for example on ruderal habitats such as roadsides. The results of our observations confirm the presence of the species on beaches and rocky bank reinforcement, with accumulation of annual vegetation in the Hel Peninsula and Puck Bay. Five sites, where Atriplex littoralis specimens occur have been found. In each site 1 to 15 specimens where found, in total 31. Five phytosociological relevés were made within the floristically poor patches of Matricario maritimae-Atriplicetum littoralis (Christiansen 1933) R.Tx. 1950. This association represents the protected type of habitat: Annual vegetation of drift lines (1210).

For the last 20 years researchers have tried to create new approaches of managing urban ecosystem by using remote sensing methods. The authors estimated the normalized vegetation index (NDVI) and moisture index (NDMI) indices of Kyiv and propose an approach which can be used for estimation vegetation of other cities. The aim of the study was to assess the indicators of NDVI and NDMI in Kyiv for the last 5 years. The authors consider the NDVI index as an important ecostabilizing component of the urban ecosystem, as well as an indicator of the well-being citizens in a modern city. The study used space images of the Sentinel-2 satellite system with resolution of 10×10 m and 10×20 m. The images were decrypted using the Sentinel Hub platform which updates the data-base daily. The paper presents the results of correlation analysis using Statistica-6.0 software and demonstrate the close relationship (r = 0.73, r2 = 0.55) between NDVI and NDMI. Thus, the statistical results of the study confirm a strong correlation between photosynthetic activity of plants and indicators of their water content by satellite imagery which allows using modern satellite technologies to assess the functional state of the urban vegetation. The changes in the length of active vegetative growth period were identified by NDVI and NDMI. The results of the research expand the directions of the methods of monitoring the condition of the urban vegetation cover in the aspect of applied landscape research.

Opis:
Erosion and sedimentation have a very big influence on flooding. Floods are strongly influenced by land use and population activities that change the river’s physical condition, including erosion and sedimentation. The river upstream was very steep, and the downstream was narrowing and meandering with high rainfall recorded. This study analyses erosion, sedimentation, and its handling using the eco-hydraulic base. The method involves input rainfall data, river hydraulics, land use, watershed area, and land cover. The analysis of hydrology, hydraulics, land use, flood discharge, and eco-hydraulic, inundation height, vegetation diameter, velocity reduced, and riverbank width measured in five bridges cross-sections along the river. The eco-hydraulic compares the width of existing riverbanks and design, high inundation, and the vegetation diameter to minimise flood discharge. Erosion in the right cliff is 22.73% and the left cliff is 37.04%, land erosion was 225.83 Mg∙ha-1∙year -1. The river’s bottom is formed by rocks of 0.18-1.30 mm. The plantation land used around the Lae Kombih River grows mainly an oil palm with a diameter of 0.5-0.7 m. The riverbank design on 100 m for vegetation diameter of 0.1-1.0 m can retain flood discharge for five years return period up to 72.3%, resulting in discharge of 112.04209.43 m3∙s-1. The largest erosion and sedimentation on the river border is Dusun Silak, so it is recommended to plant Vetiveria zizanioides, Ipomoea carnea and Bambusoideae. An inundation height of 0.9 m can be recommended to design an embankment to be used as flood mitigation.

This study investigates the lower Tigris basin’s the normalized difference vegetation index (NDVI) sensitivity in 2000–2016 to regional climate variability reflected by the monthly precipitation and temperature time series of seven global datasets as well as to four global circulation indices. To examine the effect of climate variability on the different ecosystems, the study area has been classified into 10 smaller natural and anthropogenic landscapes based on landforms and land cover patterns. The preliminary analysis showed that the maximum biological productivity reflected by the NDVI of March and April has the highest correlation (0.5–0.8) to the same cumulative amounts of October–March period total precipitation and January–March period mean temperatures according to all datasets. In addition, this article showed there is a correlation between landscapes’ NDVI and global modulation represented by the September–February state of El Nińo-Southern Oscillation (ENSO) (0.55–0.70) and December state of the dipole mode index (DMI) (0.35–0.72). The significant differences in the original precipitation and temperature levels according to the different datasets have urged the use of normalized time series: z-score of temperatures and analogous six-months the standardized precipitation index (SPI). However, the multiple correlation analysis showed that using ERA-

Opis:
The aim of this article is to assess the structure of biodiversity of field protective forest shelter belts to determine the directions of increasing their reclamation and conservation potential in the organic agricultural landscape. Methods of comparative ecology (synecological approach, assessment of α-diversity), forestry, geobotany, ornithology and statistical analysis are used. Changes in species diversity of plants and birds in forest shelter belts around organic fields are characterized. It is established that plantations with developed undergrowth and understorey are transformed due to the loss of up to 43.5% of trees, liquefaction of the edificatory tier. Transformer species with a wide phytocenotic range predominate in the tree stands. The grass tier is dominated by ruderants (36.5%) and adventive species (24.5%). The share (60%) of species with a mixed life strategy indicates changes in moisture conditions and soil trophism. A 2.4% of shade-loving plants and the presence of 14.7% nitrophils indicate an imbalance in the structure of forest shelter belts. Depletion of species composition, ecological and trophic structure of bird groups testify to the decrease in the capacity of forest shelter belts and their statio diversity, reduction of protective, environment-creating functions and other ecosystem services. In the three-tiered dense forest shelter belts with developed undergrowth and understorey, 10–27 species of birds nest. In general, avifauna is represented by 2 ecological groups (93.1% dendrophiles, 6.9% sclerophiles), divided into 5 types of nesting strategy (with a predominance of hollow-nests 37.0–53.3%), and 5 types of feeding (with a predominance of entomophagous 70.4–90.0%). Twenty-nine species have been identified on nesting, 27 of which are subject to protection at the level of international agreements. There are no adventive species, the index of synanthropization of avifauna is high – 0.85–1.0. For organic technologies to increase the potential of biological protection of fields from entomological pests by attracting insectivorous birds is relevant.

Opis:
Zasoby wodne Wielkopolski są stosunkowo niewielkie. Nawet w latach przeciętnych i mokrych w środkowej części dorzecza Warty, występują niedobory wody w okresie wegetacyjnym, w którym suma opadów waha się od 240 do 290 mm, a w latach suchych nie przekracza połowy tej wartości [2, 7]. Wielkopolska jest obszarem o największych deficytach wody w Polsce, które dodatkowo ulegają stopniowemu pogłębianiu, gdy średnie roczne opady atmosferyczne z wielolecia są niższe lub zbliżone do 500 mm. [5].Bilans wodny kształtowany jest przede wszystkim przez warunki meteorologiczne,głównie zaś przez ilość i rozkład opadów atmosferycznych oraz ewapotranspirację rzeczywistą. Woda glebowa jest dynamicznym składnikiem gleby, ulegającym zmianom w cyklu rocznym. Zmiany te są uzależnione od dopływu wody do gleby, jej krążenia w obrębie gleby oraz odpływu wody poza profil glebowy. Istotnym czynnikiem gospodarki wodnej gleb jest także poziom występowania zwierciadła wód gruntowych oraz ich wpływ na uwilgotnienie wierzchnich warstw gleby [8, 6]. Gospodarka wodna gleb decyduje zarówno o ilości wody dostępnej dla roślin w sezonie wegetacyjnym jak również o ilości wody infiltrującej przez glebę do wód gruntowych [3, 4]. Zlewnia Kościańskiego Kanału Obry, do której należy Rów Wonieść, obejmuje obszar na styku strefy brzegowej zlodowacenia bałtyckiego z płaskimi równinami morenowymi z okresu zlodowacenia środkowopolskiego [1]. Większe zróżnicowanie hipsometryczne jest rezultatem silnego rozmycia denno morenowej równiny zlodowacenia środkowopolskiego przez wody roztopowe. Utwory czwartorzędowe mają miąższość od około 20 m do ponad 80 m i reprezentowane są przez gliny zwałowe tych zlodowaceń oraz osady fluwioglacjalne i interglacjalne. Celem pracy była ocena wpływu warunków meteorologicznych na zmiany zapasów wody w analizowanych glebach na polderze Nielęgowo w okresach wegetacji lat 2005 do 2007.
Weather conditions, especially rainfalls in Wielkopolska region, are characterized by wide variability of space and time. This region is especially exposed to atmospheric,hydrologic, and soil droughts, which may diminish crops.This work presents an influence of weather conditions on changes in water retentiondynamics in soil of regions: Nielegowo and Kościański Channel of Obra duringvegetation period in 2005-2007. There have been analyzed the soil moisture, reflection of ground water profiles. Profile 1 (mursh ground) was located 15 meters from melioration ditch, and the profile 2 (mursh soil) was 400 m from the ditch mentioned above.Periods of vegetation in 2005 and 2006 shoved average rainfalls, however in the year 2007, the vegetation period was counted to average dry ones.It was found that water retention in the analyzed soil profiles depended not only on the aggregation of rainfalls but also on their distribution. On the profile 1 which was located in the region under influence of the melioration ditch, the water retention during three year period of experimentation, as well as in the 0-50 cm layer, as well as 0-100 cm , were located in the field water capacity and the critical water content. The mean level of ground water in the soil profile was 104 cm below surface layer and it exerted an influence on water content of this profile.In the profile 2, which was located 400 m from melioration ditch water retention in the soil layer 0-50cm was falling multiple times below critical soil moisture. In vegetation period in 2006, retention was getting closer to moisture of permanent wilting point. Oscillation of ground water was between 83 cm (April 2005) and 155 cm (September 2005) below soil surface.

Opis:
Effective assessment of environmental changes requires an update of vegetation maps as it is an indicator of both local and global development. It is therefore important to formulate methods which would ensure constant monitoring. It can be achieved with the use of satellite data which makes the analysis of hard-to-reach areas such as alpine ecosystems easier. Every year, more new satellite data is available. Its spatial, spectral, time, and radiometric resolution is improving as well. Despite significant achievements in terms of the methodology of image classification, there is still the need to improve it. It results from the changing needs of spatial data users, availability of new kinds of satellite sensors, and development of classification algorithms. The article focuses on the application of Sentinel-2 and hyperspectral EnMAP images to the classification of alpine plants of the Karkonosze (Giant) Mountains according to the: Support Vector Machine (SVM), Random Forest (RF), and Maximum Likelihood (ML) algorithms. The effects of their work is a set of maps of alpine and subalpine vegetation as well as classification error matrices. The achieved results are satisfactory as the overall accuracy of classification with the SVM method has reached 82% for Sentinel-2 data and 83% for EnMAP data, which confirms the applicability of image data to the monitoring of alpine plants.

Remote sensing is a convenient tool for the study of vegetation cover conditions and dynamics using normalized difference and enhanced vegetation indices. Determination of the connection between weather and vegetation indices plays an important role in better understanding peculiarities of ecosystems reaction to changing climate conditions. The study devoted to the evaluation of annual and long-term dynamics under vegetation cover conditions, and its reaction to the climate factor, was performed through the establishment of the link between remote sensing information (smoothed time series data on normalized and enhanced vegetation indices) and results of on-land hydrometeorological observations for air temperature and precipitation amounts in Kherson oblast of Ukraine during the period from 2012 to 2019 by the means of linear regression analysis of the data. The values of the studied vegetation indices (Terrain MODIS NDVI and MODIS EVI 250 m smoothed time series) were calculated and generalized by the means of GDAL raster analysis toolkit in QGIS 3.10. Statistical data processing was performed using BioStat v7 software. It was found that there is a strong tendency towards the enhancement of vegetation in the region year by year. Climate has strong effect on the vegetation, and the main input belongs to air temperature, while precipitation amounts cannot be considered as a driving force of changes in the growth of vegetation. Enhanced vegetation index seems to be more reliable for the estimation of vegetation cover conditions in comparison to normalized difference vegetation index.

Opis:
The water requirements of the wheat crop are represented by the actual evapotranspiration, which depends on the meteorological data of the study area and the amount of water consumed during the season. Estimation of crop coefficients (Kc) and evapotranspiration (ETc) using remote sensing data is essential for decision-making regarding water management in irrigated areas in arid and semi-arid large-scale areas. This research aims to estimate the crop coefficient calculated from remote sensing data and the actual evapotranspiration values for the crop. The FAO Penman-Monteith equation has been used to estimate the reference evapotranspiration from meteorological data. Linear regression analysis was applied by developing prediction equations for the crop coefficient for different growth stages of comparing with the vegetation cover index (NDVI). The results showed that (R2 = 0.98) between field crop coefficient and crop coefficient predicted from (Kc = 2.0114 NDVI-0.147) in addition to (RMSE = 0.92 and (d = 0.97).

Opis:
The increase of interest in golf playing, observed in recent years in Poland, is a reason for the growing demand for building new golf courses. It generates the need for creating an assessment methodology for the solutions used when designing and realizing golf courses. Turf value is a crucial component that affects games quality, therefore valuation of turf is very important (Turgeon, 2004). However, for many players also important are landscape values, which create a setting for playing golf. For this reason, creating a separate, universally used methodology of valuation the golf course landscape is an important aspect. The present paper shows the methodology of golf course landscape assessment by the example of the Toya Golf & Country Club – Wroclaw at Krzyżanowice. The assessment presented includes five aspects: compatibility of the golf course with the surroundings (compatibility of trees and water plants, architectonics and influence on surroundings), the harmony of design and performance (analysis of the landscape dominants used, of view axis, selection of colors and use of helioplastics), the vertical and habitant variety that includes an assessment of distribution of obstacles on a golf course, functionality (play safety and universality) and originality of solutions applied in a golf course. The aspects mentioned are assessed using a point scale and the final value is the sum of partial values.

Opis:
In Chernihiv Polesie Solidago canadensis most often grows in ruderal communities of the Berteroëtum incanae association. Characteristic plant species of the Artemisietea vulgaris class have been found in many phytocenoses with Solidago canadensis. A typical ruderal community dominated by S. canadensis was found, in which characteristic species of the xero-mesophytic ruderal vegetation of the Onopordion acanthii are well represented. Initial communities with the S. canadensis coverage of 25 to 60% in combination with the species of this order and the characteristic species of other high syntaxa were found. Most of them are the transformed meadow phytocenoses of the river floodplains and less often – the psammophytic phytocenoses of pine terraces. The process of ruderalization of meadow ecosystems as a result of the invasion of S. canadensis in Chernihiv Polesie was revealed. This process is especially pronounced on the loess islands, where meadows change into semiruderal grasslands and herblands of the Convolvulo arvensis – Agropyrion repentis alliance. S. canadensis invasion leads to xerophytization and unification of the floodplains meadow phytocenoses grassland. The course of these processes is accelerated by anthropogenic pressure on ecosystems and has irreversible consequences. S. canadensis rarely occurs in the Koelerio–Corynephoretea canescentis class psammophytic communities.

The organic sediments at the Cheremoshnik site (the centre of the East European Plain) have been reinvestigated by pollen and macrofossil analysis in order to gather more detailed information on vegetation dynamics during the Late Pleistocene Glacial/Interglacial transition (boundary between OIS 6 and OIS 5e). Two phases of vegetation can be determined: an earlier forest substage ("warm") and a later ("cold") substage, when the forest communities were reduced in their area. There are probably some similar features between the succession of vegetation at the end of Dnieper (Saale) cold epoch and during the Valdai (Weichselian) Late Glacial (Alleröd and Younger Dryas).

Opis:
Expansion of invasive species can be clearly seen all over Poland. Foreign tree and herbaceous plant species are effectively taking over more and more habitats competing with native vegetation. This phenomenon is strongly pronounced in the areas subject to strong anthropogenic pressure. The presence of invasive plants replacing the native vegetation is a threat for biodiversity and ecological balance. The research carried out by the authors between 2011 and 2017 on selected sites (comparatively: urban and open spaces, including a 600 ha park and a 10 km long forest strip along a river) confirms the pressure exerted by invasive species irrespective of the natural conditions of a particular site or its type – in each case it is most prominent in areas where vegetation is not properly maintained or where it is not maintained at all. The research was based on the dendrological inventories and phytosociological assessments. The inventories were used for a detailed assessment of both the condition and structure of treestands, including accounting for invasive species. Phytosociological assessment can, among others, form a basis for forecasting ecological stability of individual plant communities. Uncontrolled expansion of invasive species, especially in the areas of strong anthropogenic pressure, may cause unfavourable natural succession and in consequence – destabilisation of ecological system in a given area.

Landslide is one of the most common natural disasters in Indonesia. In Lut Tawar Lake, specifically the cliff side, the landslide event occurs almost daily. Mitigation effort becomes a necessity following the fatality cases it causes. This study aimed to identify landslides and suitable mitigation for the case of Lut Tawar’s lake cliff. A combined approach of landslide survey and image interpretation with field validation was used. In addition, local vegetation surrounding the case area was identified from the survey and interview process. The results showed there are in total 37 landslide points in the study area. The conducted analysis showed the landslide was mainly caused by land use change from forest to a plantation, slope, particularly in the cliff area that was carved for road development, the volcanic geology of Bukit Barisan mountain, rainfall intensity, and the equatorial rainfall characteristic of the study area. The results also suggest the finest solution for landslide mitigation, namely the eco-engineering approach, a revegetation method using the local vegetation. Local vegetation comprises multiple strata, of which grass in the below strata, shrubs in the middle strata, and trees in the upper strata, constitute a shield for the lake cliff. Within this structure, government and community can cultivate these plants in the surrounding lake area.

Opis:
The study has been carried out at the Biebrza Basin in Poland. The investigation aimed at finding the best vegetation index characterising different marshland habitats. The various indices were calculated on the basis of all considered spectral bands of low spatial resolution satellites as SPOT/VEGETATION, ERS-2/ATSR, and NOAA/AVHRR. The GEMI and EVI index calculated from SPOT/VEGETATION images was the best for distinguishing vegetation classes. The best correlation between LAI measured at the ground and the derived indices was with GEMI and EVI index. Soil moisture values calculated from ERS2/ SAR well characterised distinguished marshland humidity classes.
Biebrzański Park Narodowy został założony w 1993 roku w celu ochrony unikalnych walorów przyrodniczych bagiennej doliny rzeki Biebrzy. W wyniku panujących warunków wodnych oraz morfologii terenu na obszarze tym wykształcił się największy w Polsce ekosystem torfowisk niskich i wysokich. Na skutek zmian w użytkowaniu rolniczym oraz z powodu budowy kanałów odwadniających, ten unikalny naturalny ekosystem bagienny został zachwiany. Zmienione warunki wilgotnościowe doprowadziły do degradacji gleb torfowych i w konsekwencji do zmiany szaty roślinnej. Obecnie istnieje potrzeba monitorowania niekorzystnego dla środowiska procesu osuszania bagien, a jedynie możliwą do zastosowania na tak dużą skalę metodą, jest metoda teledetekcji. Badania skoncentrowano na obszarze zlokalizowanym w Basenie Środkowym Biebrzy, na którym do tej pory przeprowadzono wiele eksperymentów naukowych, i dla którego zgromadzono wiele informacji niezbędnych do realizacji niniejszego przedsięwzięcia. W opracowaniu uwzględnione zostały dane satelitarne i naziemne archiwalne pochodzące z lat 1995 i 1997 oraz dane otrzymane w trakcie trwania badań lat 2000–2002. Wykorzystano dane satelitarne otrzymywane w optycznym i mikrofalowym zakresie widma elektromagnetycznego. Z zakresu optycznego (Landsat ETM, ERS-2.ATSR, SPOT VEGETATION, NOAA/AVHRR) zostały wyznaczone wskaźniki roślinne charakteryzujące powierzchnię ze względu na stopień uwilgotnienia i fazę rozwoju roślin. Poprzez klasyfikację obszaru wyróżniono łąki na różnych rodzajach siedlisk. Klasyfikowane były zdjęcia wykonane przy użyciu skanerów Thematic Mapper (TM) i Enhanced Thematic Mapper (ETM+) pracujących na satelitach z serii Landsat oraz zdjęcia mikrofalowe wykonane przy użyciu urządzenia SAR umieszczonego na satelicie ERS-2. Przy klasyfikacji wykorzystano wyniki badań terenowych. Z danych mikrofalowych zarejestrowanych przez satelitę ERS-2 obliczono współczynnik wstecznego rozpraszania i wyprowadzono algorytmy wyznaczania wilgotności gleby. Wyznaczono również związek pomiędzy poszczególnymi klasami wilgotności gleby a wskaźnikami roślinnymi uzyskanymi z różnych satelitów oraz wyznaczono obszary, na których zaszły największe zmiany wilgotności. W wyniku przeprowadzonych analiz wybrano następujące wskaźniki roślinne: ARVI, EVI, GEMI, MI, NDVI, których wzory podane są poniżej: ARVI = ( NIR - BLUE ) / ( NIR + BLUE ) EVI = 2.0 * ( NIR - RED ) / ( 1 + NIR + 6 * RED - 7.5 * BLUE ) GEMI =⋅[η * ( 1 - 0.25η ) - ( RED - 0.125 )] / [ 1 - RED ], η = [ 2 * ( NIR2 - RED2 ) + 1.5 NIR + 0.5 RED ] / 9 NIR + RED + 0.5 ] NDVI = ( NIR - RED ) / ( NIR + RED ) MI = ( SWIR - RED ) / (SWIR + RED ) gdzie: ARVI – Atmospherically Resistant Vegetation Index, Kaufman i Tanre, 1992; EVI – Enhanced Vegetation Index, Liu i Huete, 1995; GEMI – Global Environment Monitoring Index, Pinty i Verstraete, 1992; MI –Medium Infrared Index, wyprowadzony przez autorów, 2002; NDVI – Normalized Difference Vegetation Index, powszechnie używany od dawna. Wskaźniki roślinne łączą dane teledetekcyjne z biofizycznymi charakterystykami powierzchni czynnej, a w szczególności z powierzchnią projekcyjną liści, akumulowaną radiacją w procesie fotosyntezy, biomasą, i gęstością pokrycia roślinnością. Istnieje duże zainteresowanie rozwijaniem i wprowadzaniem wciąż nowych indeksów ze względu na ich związek z wieloma cechami roślinnymi, a równocześnie nie czułych na osłabiający wpływ gleby i atmosfery. Pozostaje jednak nadal aktualne, jakie cechy roślin wpływają na wartość wskaźnika, dla jakich warunków dany indeks może być zastosowany, jak również z jaką dokładnością mogą być poszczególne parametry roślinne obliczane. Wskaźniki roślinne, ze względu na łatwość ich obliczania bez konieczności stosowania dodatkowych danych, znalazły zastosowanie w rolnictwie do prognozowania plonów, ustalania terminów nawodnień. Istotnym elementem pracy było znalezienie takich wskaźników roślinnych obliczanych ze zdjęć satelitarnych wykonanych w optycznym zakresie widma, które pozwoliłyby na dokładne szacowanie wskaźnika powierzchni projekcyjnej liści tzw. LAI. Wskaźnik ten jest niezbędny do szacowania wilgotności gleby ze zdjęć mikrofalowych, gdyż odzwierciedla szorstkość badanej powierzchni roślinnej. Analiza zmian wilgotności gleby umożliwiła wyznaczenie obszarów o zróżnicowanym uwilgotnieniu i opracowanie metody jej monitorowania na obszarach bagiennych. Najsilniejszą zależność otrzymano dla wskaźników EVI i GEMI obliczonych z danych satelitarnych SPOT VEGETATION (R2 = 0.81), najsłabszą dla wskaźnika GEMI obliczonego z danych NOAA/AVHRR (R2 = 0.41). Wyprowadzone na podstawie analizy statystycznej algorytmy o najwyższych korelacjach mogą być zastosowane do szacowania wskaźnika LAI dla roślinności bagiennej.

W pracy oceniono rekultywację leśną na zwałowisku odpadów po wydobyciu węgla kamiennego KWK „Brzeszcze” w Brzeszczach. Wprowadzona na zwałowisko roślinność drzewiasta cechuje się dobrą żywotnością i jakością oraz spełnia liczne powierzone jej funkcje od ochronnych do krajobrazowych. Prawidłowy wzrost i rozwój wprowadzonych drzew w dużej mierze umożliwiła poprawnie wykonana rekultywacja techniczna, zwłaszcza nawiezienie odpowiedniej miąższości (40 cm) i jakości wierzchniej warstwy gleby.
The present study assesses the forest reclamation of the hard coal waste heap at the “Brzeszcze” hard coal mine in Brzeszcze. The arborescent vegetation introduced at the waste heap is characterised by good vitality and quality and it fulfills its numerous functions, from protective to landscape ones. To a large extent, the proper growth and development of the introduced trees has been made possible by the correct execution of technical reclamation, particularly bringing the surface soil layer (40 cm) with proper volume and quality.

Opis:
Forest fires influence significantly on the natural environment, forest management and economy. Therefore, it is very important to predict the susceptibility of the object to damage caused by fire. There are a lot of vegetation indexes obtained from the satellite images which are used to forecast the fire hazard. The aim of the study is to verify which vegetation index is the most appropriate to foresee the fire intensity. The study was carried out for the fi res which occurred in Greece in August 2007. The analyzed area had 190 000 ha. MODIS data were used in the study. The paper presents the results of the correlation analysis for some of vegetation indexes: NDVI – Normalized Difference Vegetation Index, NDII - Normalized Difference Infrared Index, NDWI – Normalized Difference Water Index, GVMI – Global Vegetation Moisture Index, SRWI - Simple Ratio Water Index, SIWSI(6,2) – Shortwave Infrared Water Stress Index and indexes of fi re intensity: BAI – Burned Area Index and NBR – Normalized Burn Ratio. The analysis shows that the vegetation condition is only one of the many factors which control the forest fire intensity. The correlation between vegetation and fire intensity indexes varies depending mainly on weather condition; especially maximum wind speed and the content of water vapour and secondarily on the type of vegetation cover. The most suitable vegetation indexes to predict the fi re intensity resulted to be the NDII and SIWSI(6,2), which present Pearson correlation of 0,66. The correlation is usually better for the BAI fi re intensity index then for the NBR. The only exception is the case of forest.

Soybean is a photophilic and thermophilic plant with short-day photoperiodism. Therefore, special attention should be paid to proper seed sowing in soybean agriculture practice. The aim of the experiment was to evaluate soybean response to different seed sowing time points. The main plots were three sowing dates scheduled each year at about 10-day intervals (19/04/2016, 29/04/2016, 9/05/2016, 13/04/2017, 24/04/2017, 2/05/2017, 16/04/2018, 27/04/2018, 7/05/2018). Subplots were three soybean varieties: Aldana, Merlin and Lissabon. Weather conditions varied in years and had an effect on the study results obtained. The early date of sowing reduced plant density before harvest in comparison with later sowings. The growing season of plants shortened as the sowing date was delayed. The early sowing date increased the number of pods per plant and thousand seeds weight (TSW) in relation to the optimal time point. Protein content in seeds was significantly higher after sowing the seeds in a delayed period compared to the early date. The early sowing date increased the content of phosphorus and potassium in the seeds. The yield of seeds, protein and fat did not vary depending on the sowing date. However, they varied in the successive years of research. In 2017, plots with a delayed sowing date gave a significantly higher seed yield compared to the early date. The early variety Aldana yielded significantly lower than the mid-early varieties Merlin and Lissabon. The low SPAD index (soil plant analysis development) and high LAI index (leaf area index) were determined in the variety Lissabon.

Opis:
The increase in demand for food and the need to predict the impact of a warming climate on vegetation makes it critical that the best tools for assessing crop production are found. Chlorophyll fluorescence (ChlF) has been proposed as a direct indicator of photosynthesis and plant condition. The aim of this paper is to study the feasibility of estimating ChlF from spectral vegetation indices derived from Sentinel-2, in order to monitor crop stress and investigate ChlF changes in response to surface temperatures and meteorological observations. The regressions between thirty three Sentinel-2-derived VIs, and ChlF measured on the ground were evaluated in order to estimate the best predictors of ChlF. The r-Pearson correlation and polynomial linear regression were used. For maize, the highest correlation between ChlF and VIs were found for NDII (r=0.65) and for SIPI (r=-0.68). The weakest relationship between VIs and ChlF were found for sugar beets. Despite this, it should be noted that the highest correlation for sugar beets appeared for EVI (r=0.45) and S2REP (r=0.43). The results of this study indicate the need for a synergy of low and high resolution satellite data that will enable a more detailed analysis for estimating fluorescence and its relation to climatic conditions, environmental aspects, and VIs derived from satellite images.

Opis:
Remote sensing from unmanned aerial systems (UAS) has been gaining popularity in the last few years. In the field of vegetation mapping, digital cameras converted to calculate vegetation index (DCVI) are one of the most popular sensors. This paper presents simulations using a radiative transfer model (libRadtran) of DCVI and NDVI results in an environment of possible UAS flight scenarios. The analysis of the results is focused on the comparison of atmosphere influence on both indices. The results revealed uncertainties in uncorrected DCVI measurements up to 25% at the altitude of 5 km, 5% at 1 km and around 1% at 0.15 km, which suggests that DCVI can be widely used on small UAS operating below 0.2 km.

Opis:
Many terrestrial pollen profiles from Poland (and a few pollen records from other parts of Central Europe) show the end of the last interglacial (Eemian, MIS 5e) to have been characterized by climatic and environmental instability. This is expressed by a strong, rapid cooling in the middle part of the pine phase ending this interglacial (E7 regional pollen assemblage zone), and then a re-warming at the very end of this phase, immediately before the transition to the glacial conditions of the last glaciation (Vistulian, Weichselian, MIS 5d). We have characterized the regional distribution of these climatic fluctuations in Poland on the basis of isopollen maps prepared for the Eemian Interglacial based on palynological data from 31 Polish pollen profiles. These maps show unequivocally that the intra-interglacial cooling at the end of the Eemian Interglacial was a transregional phenomenon, which was reflected very clearly by a temporary openness of vegetation across the whole of Poland. It was associated with a distinct decrease in pine forest areas and an increase in birch forests and open communities of cold steppe type with a domination of Artemisia. The pronounced climate and environment instability during the last phase of the Eemian Interglacial may be consistent with it being a natural phenomenon, characteristic of transitional stages. Taking into consideration the currently observed global warming, coinciding with a natural cooling trend, the study of such transitional stages is important for understanding the underlying processes of climate change.

Opis:
The heat resistance of vegetation at landfills is worth investigating for the determination of the optimal species for the biological reclamation phase. Insufficiency of experimental data on comparative stability of the stems and roots make it difficult to draw definitive conclusions about the heat resistance of the organs of the plants. It should be noted that many scientific works are devoted to the thermal stability of cultivated and agricultural plants. The reason is that the temperature conditions should be taken into account when growing vegetables, fruits and mushrooms. However, the heat resistance of weeds, specifically in landfills, has not been investigated thoroughly enough. Increased substrate temperatures at the landfill site, which are caused by the burning of waste, alter the microclimate, cause the greenhouse effect, and contribute to the climate change. The aim of the work was to investigate the heat resistance of 5 most common plant species that have evolved in the landfills of the Western Ukrainian Forest-Steppe District (Ukraine). The plant specimens were collected at the Lviv, Rava-Ruska and Chervonograd landfills. The heat resistance of landfill vegetation was determined according to the Matskov method during 2015–2018. The following materials, reagents and equipment were used for the experiments: green leaves of 5 species of the investigated plants (weeds) – wormwood (Artemisia vulgaris), absinthium (Artemisia absinthium), city goosefoot (Chenopodium urbicum), common burdock (Arctium lappa), dooryard plantain (Plantago major); 0.2 N hydrochloric acid; heated bath, thermometers, pipettes, petri dishes, crystallizers, electric hot plate, marker. The experiments were conducted in triplicate. During the investigation of the heat resistance of the landfill vegetation, it was found that the most stable species are wormwoods (Artemisia) in all areas of the landfill, and the least heat-resistant is city goosefoot. The temperature of 70–80°C is detrimental to all of the tested plants. It was found that the lowest heat resistance is characteristic of the plants that develop at the foot of landfills.

Opis:
The movement of water on flood areas depends mainly on the geometric parameters of vegetation, which as a dynamic factor causes a high changeability of flow conditions during the year. The actual ecological trend, whereby there is a tendency to leave the plants in the floodplain, imposes the necessity on engineers to develop accurate methods of determining the effect of vegetation on what used to be once a commonly occurring flood risk. According to the report on national security risk, elaborated by the Government Security Centre, flooding is the most common such risk. This is most likely to occur among all the risks included in the National Crisis Management Plan and brings the greatest number of negative effects. In order to mitigate the negative phenomena related to floodplains, the methodology and calculation of the average flows, using the Maninng and Darcy-Weisbach models is presented.

Drogi są liniowymi elementami krajobrazu pochodzenia antropogenicznego. Ich integralność z otoczeniem zależy m.in. od roślinności. W ostatnich latach nasilają się głosy nawołujące do wycinki przydrożnych drzew, gdyż stanowią one zagrożenie dla kierowców, a przecież wg Ustawy z dnia 21 marca 1985 r. o drogach publicznych główną funkcją zieleni przydrożnej jest szeroko rozumiana ochrona. Jednak znaczna część poboczy w Polsce porośnięta jest jedynie przez roślinność określaną przez GDDKiA jako „niska zieleń przydrożna”. Warto zatem rozważyć w jakiej kondycji znajduje się owy element szaty roślinnej. W latach 2014-2015 przeanalizowano projekty zieleni przydrożnej przy drogach ekspresowych budowanych w województwie mazowieckim i lubelskim, co umożliwiło waloryzację i przedstawienie struktury.

Opis:
In turbulent flow, the Reynolds stress provides an understanding of the shear dispersion within the flow. Turbulence can be said to have an effect equivalent to the Reynolds shear stresses and are indicators of turbulence transport. This paper examined the characteristic of vertical Reynolds Shear stress in a patchy heterogeneous open channel using two experimental conditions for flexible and rigid vegetation interaction with gravel bed. The results show the value of vertical Reynolds stress decreases downstream along the channel section and as the distance from change in roughness increases. This is attributed to the effects of the bed roughness configuration (due to the preceding vegetated bed roughness) on the vertical Reynolds stress distribution. However, the position of maximum vertical Reynolds stress is located near bed over the vegetated zone. This provides an indication that the vegetated bed serves as the primary source of turbulence for the flow.

Opis:
Small, astatic ponds are important features of post-glacial landscape, which support heterogeneity and biodiversity of agricultural areas. In the presented research we explored differences in hydrochemistry and plant cover of 20 small ponds located in Northeastern Poland, characterized by diverse age and developed in differently managed areas. According to our research, though changes in water level are under direct influence of water balance in the catchment, to which belonged the ponds, their hydrochemistry seemed to be shaped by processes at the level lower than the catchment scale. Age of the ponds appeared to be an important factor influencing density and species composition of vegetation developed on the studied ponds.
Badania prowadzono przez dwa lata na małych zbiornikach wodnych w krajobrazie porolnym w Mazurskim Parku Krajobrazowym. Wybrano 20 zbiorników podzielonych na trzy grupy różniące się wiekiem, stopniem odizolowania i sposobem zagospodarowania otaczających je terenów. Regularnie monitorowano właściwości chemiczne wody w zbiornikach. W celu oszacowania różnic w pokrywie roślinnej zbiorników wykonano zdjęcia fitosocjologiczne metodą Brauna-Blanqueta. Wykazano, że nowopowstałe zbiorniki istotnie statystycznie różnią się od starych poziomem wody, jej odczynem i zawartością jonów wapnia. Najwyższy poziom wody zarejestrowano w starych zbiornikach położonych w otoczeniu półnaturalnych wilgotnych łąk, największą wartość pH i największe stężenie jonów wapnia – w nowopowstałych zbiornikach. We wszystkich badanych grupach zbiorników poziom wody i wartości badanych parametrów chemicznych podlegały zmienności sezonowej. Roczna dynamika właściwości chemicznych wody nie wykazywała związku z fluktuacjami poziomu wody. Parametry chemiczne wody w starych zbiornikach położonych wśród pól uprawnych nie różniły się od notowanych w starych zbiornikach położonych na obszarze łąk półnaturalnych. Na nowopowstałych zbiornikach dominowały zbiorowiska charakterystyczne dla otwartej toni wodnej. Brzegi młodych zbiorników charakteryzowały się znacznym udziałem błotnistych, luźno pokrytych roślinnością powierzchni. Różnorodność flory młodych zbiorników, wyrażona liczbą gatunków oraz współczynnikiem Shannona- Weavera, była istotnie mniejsza niż w starych zbiornikach. Zbiorniki stare na półnaturalnych łąkach cechował duży udział gatunków charakterystycznych dla rzędu Molinietalia caeruleae W. Koch 1926 oraz dla związku Magnocaricion Koch 1926. W grupie tych zbiorników zarejestrowano największe wartości wskaźników różnorodności biologicznej. Na starych zbiornikach otoczonych polami uprawnymi dominowały pałkowiska Typha latifolia. Zaobserwowano także liczne gatunki charakterystyczne dla siedlisk przekształconych przez człowieka (gatunki ruderalne, chwasty).

Opis:
The paper presents palynological data from Bieganin, a village located near Kalisz, Central Poland, where organic sediments were deposited in a subglacial trough dating from the Wartanian Glaciation. The succession of vegetation is characteristic of the Eemian Interglacial. The pollen diagram indicates six local pollen assemblages: B1-Pinus-Betula, B2-Betula-Pinus-Ulmus, B3-Quercus-Corylus, B4 -Corylus, B5-Carpinus-Tilia-Polypodiaceae, B6-Pinus-Picea which correlate well with regional pollen assemblages obtained by Mamakowa (1989b) and Tobolski (1991). The plant succession in Bieganin started in the beginning of the Eemian (zone E1) and ended with the development of coniferous forest (zone E6). The profile does not include the final zone, E7, of the interglacial.

Opis:
W pracy przedstawiono wyniki badań nad zastosowaniem zintegrowanych danych z lotniczego skanowania laserowego (ALS) oraz zobrazowań satelitarnych (GeoEye-1) w celu automatycznego kartowania roślinności (obiektowa analiza obrazu) oraz generowania wskaźników przestrzennych 3D opisujących w sposób syntetyczny strukturę roślinności. Utworzone wskaźniki charakteryzują zróżnicowanie pionowe roślinności wysokiej (VDI – Vegetation Diversity Index) oraz objętość wypełnionej przez nią przestrzeni (FR – Filling Ratio, V2A – Volume to Area). Ponadto opracowany został wskaźnik VV2BV (Vegetation Volume to Built-up Volume) wyrażający stosunek objętości roślinności do objętości (kubatury) budynków. Wskaźnik ten stosowany może być do przyrodniczej waloryzacji obszarów zabudowanych.
The paper presents results of studies on the application of integrated data from airborne laser scanning (ALS) and satellite imagery (GeoEye-1) for the automatic mapping of vegetation (object-oriented image analysis) and to generate 3D spatial indices describing the structure of the vegetation. Created indices characterize the vertical diversity of vegetation (VDI – Vegetation Diversity Index) and the amount of space filled by vegetation (FR – Filling Ratio, V2A – Volume to Area). In addition, the VV2BV index (Vegetation Volume to Built-up Volume) is expressing the ratio of volume of vegetation to volume of buildings. This indicator can be applied for valorization of built-up areas.

Opis:
The paper discusses the issues associated with the geoecological rendition of high mountains, taking as a basis the authors’ studies of interrelations between relief and vegetation. The fundamental prerequisites for these studies are presented, with emphasis on the fact that the relation between the two elements is indirect and takes place via the intermediary of the habitat. With respect to the scales, both spatial and temporal, applied in the study of landscape, it is established that the majority of relations between vegetation and relief is analysed on the micro-scale, and much less frequently on the meso-scale. Application of areal methods in respective studies provides the possibility of determining the measure of relation between the elements considered. The linear methods (like, e.g., the catena method) allow for grasping the gradient differentiation of the spatial patterns on high mountain slopes. It was established that the main source of problems with landscape representation of high mountains is the mosaic character of the landscape structure. Due to this, even though the interrelations between the elements of the environment – including relief and vegetation – are distinctly visible, they have not been made precise enough with the mathematically defined dependencies, which make development of models of structure and functioning of high mountain slopes more difficult.

Teren zalewowy jest to pas ziemi leżący wzdłuż cieków wodnych, porośnięty często łęgowymi zespołami roślinnymi związanymi funkcjonalnie z wylewami rzeki i stanowiący strefę przejściową do ekosystemów roślin grądowych. Bardzo często roślinność występująca w tym pasie złożona jest z roślin jednorocznych, krzewów oraz drzew, o różnej wysokości i charakteryzujących się różnym zagęszczeniem. Część z tych obszarów wykorzystywana jest rolniczo jako pastwiska i łąki, z których można uzyskać paszę dla zwierząt. Na podstawie dokumentacji fotograficznej terenów zalewowych i badań terenowych przeprowadzanych w powyżej zbiornika Jeziorsko wykazano istotne różnice w sposobie zagospodarowania w analizowanych przekrojach dolinowych. Znacznie mniejszy rozwój roślinności krzewiastej, a właściwie jej brak obserwuje się na obszarach wykorzystanych do wypasu bydła.
Flood plains are a specific sedimentary environment. They constitute a natural clarifier tank and filter for rivers carrying various impurities including: heavy metals and biogenic elements, which are transported during floods and floods. Much of these pollutants are accumulated on the river bank called a bufferstrip. It comprises a strip of land lying along the watercourses, often overgrown with riparian plant associations related functionally to the flooding of the river and forming a transition zone ecosystem of oak-hornbeam forest plants. The vegetation found in this strip is very often made up of annual plants, shrubs and trees of different heights and characterized by diversified density. Some of these areas are used for agriculture as pastures and meadows, providing animal feed. On the basis of aerial photographs, maps and studies, significant differences in the way development in the analyzed part of valley is shown. Much smaller growth of shrubs of a complete lack thereof is observed in the areas used for grazing cattle. Despite the favorable conditions (access to water and light), the continuous grazing on vegetation by animals did not develop in a manner threatening the reduction of floodplains bandwidth.

Opis:
The water regime is the main factor contributing to the formation of landscapes in the river deltas of arid zones, any fluctuations in which lead to a change in the integral hydromorphic landscape. After the construction of the Kapshagai reservoir, the anthropogenic load on the ecosystem of the Ili River delta increased, as a result of which degradation processes, such as drying out and salinization, intensified. In the short term, this phenomenon may lead to the desertification of about 1 million ha of land in the modern river delta. In this regard, the main goal of this study is to look at the processes of desertification in the modern delta of the Ili River, using remote sensing data, which allows for quick identification of the long-term dynamics of degradation processes. For this, the authors used satellite data from Landsat 1–5 MSSS and Landsat 8OLI satellites for 1979 and 2019 and soil analysis data obtained through the ground (field) surveys. Using regression analysis of space and soil data, predictors for interpreting space images were identified and maps of landscape drying and soil salinization were compiled, reflecting the changes that have occurred over the past 40 years. As a result, it was found that in 2019, compared to 1979, the area of landscapes covered with vegetation had decreased by 12% and there was a transformation of hydromorphic landscapes into salt marshes and solonetzes. Over the past 40 years, the volume of non-saline soils has decreased by 41.3% and the volume of saline soils has increased to varying degrees. That is, at present, on the territory of the modern delta, a difficult land improvement situation has developed associated with the cessation of spring and summer floods due to the intensive water use at the Chinese and Kazakh sides.

The development of reconstructed woody vegetation on coal mine dumps during the trajectory of reclamation was explicitly investigated by means of a rehabilitation technique. However, limited information is available about the composition of herbaceous species during the ecosystem re-development on mine dumps. The present study attempted to assess the composition of herbaceous vegetation beneath plantation stands of four native woody species on the coal mine spoil in a dry tropical environment. After a thorough survey of the study site, a total of 44 species of herbaceous plants belonging to 14 families were recorded. Among the recorded plant families, the Poaceae contributed the highest number of species (18) across all ages of all plantation stands. The biodiversity parameter such as species richness exhibited an increasing trend with age under plantation stand of T. grandis only, while the rest of the plantations showed a decreasing trend. In terms of the similarity index, the plantation stands of A. procera and T. grandis were closer to each other while A. lebbeck and D. strictus were farthest apart. However, the highest IVI was recorded in the seedling of A. lebbeck under the planted stand of A. lebbeck while lowest of Rungia repens (2.85) under A. procera stands at 17th-year of age. In conclusion, the plantation age, dominant tree species, and species specificity have a significant impact on the development of herbaceous vegetation beneath the plantation stand of four native woody species.

Opis:
Land degradation, including pasture lands is one of the global problems. Currently, one of the most urgent problems of the West Kazakhstan region is the preservation and restoration of the vegetation cover of pasture lands. To date, large areas of the region have been occupied by agricultural land. Several main reasons negatively affect agriculture, one of which is land degradation associated with anthropogenic impact in terms of the irrationality of land use. Thus, to preserve the biodiversity of the pastures of the West Kazakhstan region, it is necessary to fully study the projective cover of the vegetation, determine the dominant plant species, and also monitor the condition of pastures to prevent land degradation on time by conducting land and forest improvement activities. The study aimed to carry out a phyto-ecological assessment of degraded pastures of the Karatobinsky district of the West Kazakhstan region using geoinformation technologies and field study results. The paper presents the results of desktop decoding of high-resolution satellite images and ecological profiling of the studied territories. Decoding features of landscape types allowed making a preliminary map of landscape contours. The use of this technique makes it possible to monitor the condition of degraded pasture lands in a short time and justify the organization of pastures with a regulated grazing system in the study area.

Doświadczenie przeprowadzono w latach 1997–1999 na plantacji dwuletniej. Badano wpływ terminu zbioru na plon świeżego ziela, powietrznie suchego ziela oraz powietrznie suchych liści szałwii lekarskiej (Salvia officinalis L.) odmiany ‘Bona’. Plantacja została założona każdorazowo w roku poprzedzającym badania poprzez sadzenie rozsady szałwii w ostatniej dekadzie maja (w 1996, 1997 i 1998 roku). Rozsadę posadzono w rozstawie 30×40 cm. Surowiec zebrano w dwóch terminach: w maju i we wrześniu. Wykazano istotny wpływ terminu zbioru na plon świeżego ziela szałwii lekarskiej w drugim roku użytkowania plantacji. Plon świeżego ziela uzyskany we wrześniu był większy (190,2 dt·ha⁻¹) aniżeli w maju (104,7 dt·ha⁻¹). Również zawartość olejku eterycznego w surowcu szałwii (liść, ziele) zebranym w drugim terminie (wrzesień) była większa niż w pierwszym (maj).

The effect of time of harvest on yield of fresh herb sage and yield of air dry herb, yield of air dry leaves sage. The experiment was conducted with sage two-year old. Sage transplants were planted in distance 30×40 cm. The plant material was harvested twice – in May and in September. Harvest date hat significant influence on the weight of fresh sage herb. Yield of fresh sage herb in September was bigger (190.2 dt ha⁻¹) than yield of fresh sage herb in May (104.7 dt ha⁻¹). The percentage quantity of the essential oil in the herb and leaves of sage was depended on the harvest date. The herb and leaves of sage in September had bigger the percentage quantity of the essential oil than in May. The percentage quantity of the essential oil in the leaves of sage, witch was collected in September amounted above 1.5%.

In this article the author argues that in the works of Camus people are particularly associated with vegetation. Joanna Roś analyzes the selected passages from the three literary works by Albert Camus, successively proving that: in The first man the fun with a palm tree is a symbol of passion for life, which is inextricably linked with nature as a model of survival; in Happy death vegetation teaches the hero that what would dishonor him as a man is the desire of death, denial of life; and Camus, presenting in The Minotaur or The Stop in Oran this city as a place where vegetation is masked, shows how this space devoid of vegetation urges a man to seek a counterbal-ance in a wild nature.

Opis:
Wyróżnienie i identyfikacja obiektów wojskowych maskowanych i nie maskowanych jest głównym celem wojskowego rozpoznania obrazowego. Rozpoznanie obiektów może odbywać się przy wykorzystaniu technik hiperspektralnych, które umożliwiają tworzenie stycznych, nierozłącznych i bardzo wąskich zakresów rejestracji. Pozyskane w ten sposób zobrazowania w zakresie VIS oraz NIR, mogą być wykorzystane w celach rozpoznania na różnych poziomach szczegółowości. W dobie rozwijających się technik rozpoznawczych pojawiła się potrzeba prowadzenia rozpoznania w czasie rzeczywistym, dlatego też prowadzono badania nad wykorzystaniem wskaźników wegetacyjnych (jak np. NDVI) w celu wyróżnienia obiektów sztucznych z naturalnego tła. W artykule przedstawiono prace doświadczalne związanie z doborem odpowiednich scen hiperspektralnych dla wybranego wskaźnika wegetacyjnego. Analizy dokonano na podstawie obrazów hiperspektralnych roślin naturalnych i sztucznych. Istnieje potrzeba prowadzenia dalszych prac badawczych nad doborem optymalnego zakresu, w którym występują największe różnice pomiędzy charakterystykami odbiciowymi wyróżnianego obiektu i tła. Jednocześnie zastosowanie filtru elektrooptycznego VIS ograniczyło zakres badań do 400-720nm.
As part of this study, the authors have created a set and provided the methodology for acquiring hyperspectral data in terrestrial conditions. The set is based on a monochromatic digital camera with an optoelectronic tuneable filter. In the era of developing reconnaissance techniques, there is a need for conducting such surveys in real time. The systems used to capture imagery in real time (or close to real time) should assure a shortest possible time of hyperspectral image acquisition as well as its digital processing. For the European theatre of operations vegetation is usually the typical natural background. Therefore studies were carried out on the use of vegetation indices (e.g. NDVI) in object recognition from a natural background. The article presents research regarding the process of selecting appropriate hyperspectral scenes for a given vegetation index. The analyses were carried out based on hyperspectral images of real and artificial plants. The imagery was acquired at the Military University of Technology in Warsaw, with the use of the hyperspectral system created. Based on the results described in this paper, it is safe to say that it is possible to acquire and process images which can be used in the recognition of artificial objects against a natural background in almost real time, with the use of a hyperspectral technique. There is a need to continue research into the selection of a most appropriate band in which the difference between the object sought and its background are maximised. The use of an electrooptical tuneable VIS filter has limited the analysed range to 400-720nm. Using a NIR tuneable filter instead of the VIS filter would broaden the analysed range to 650-1000nm.

Opis:
This research aims to discover the potential of hyperspectral remote sensing data for mapping mountain vegetation ecosystems. First, the importance of mountain ecosystems to the global system should be stressed due to mountainous ecosystems forming a very sensitive indicator of global climate change. Furthermore, a variety of biotic and abiotic factors influence the spatial distribution of vegetation in the mountains, producing a diverse mosaic leading to high biodiversity. The research area covers the Szrenica Mount region on the border between Poland and the Czech Republic - the most important part of the Western Karkonosze and one of the main areas in the Karkonosze National Park (M&B Reserve of the UNESCO). The APEX hyperspectral data that was classified in this study was acquired on 10th September 2012 by the German Aerospace Center (DLR) in the framework of the EUFAR HyMountEcos project. This airborne scanner is a 288-channel imaging spectrometer operating in the wavelength range 0.4-2.5 μm. For reference patterns of forest and non-forest vegetation, maps (provided by the Polish Karkonosze National Park) were chosen. Terrain recognition was based on field walks with a Trimble GeoXT GPS receiver. It allowed test and validation dominant polygons of 15 classes of vegetation communities to be selected, which were used in the Support Vector Machines (SVM) classification. The SVM classifier is a type of machine used for pattern recognition. The result is a post classification map with statistics (total, user, producer accuracies, kappa coefficient and error matrix). Assessment of the statistics shows that almost all the classes were properly recognised, excluding the fern community. The overall classification accuracy is 79.13% and the kappa coefficient is 0.77. This shows that hyperspectral images and remote sensing methods can be support tools for the identification of the dominant plant communities of mountain areas.

Polska
Opis:
The aim of this study was to characterise the flora and plant communities in the Moryńskie Hills, Poland. A total of 45 transects and 23 phytosociological relevés were established. Plant communities were identified based on the description of the test patch of the vegetation cover. The paper presents floristic analyses of vascular plants, which includes the taxonomic affiliation of species, their life forms according to Raunkiaer, and the species share in the geographical and historical groups. The results have been compiled and presented in tables and graphs, with a brief discussion. The non-forest communities occupy the largest area: xerothermic swards, meadows and pastures and to a lesser extent, scrub communities. Forests are represented by a riparian slope elm-ash wood Violo odoratae-Ulmetum minoris.

Opis:
The paper presents the first syntaxonomic classification for juniper wood communities in Tajikistan with some remarks on their environmental gradients. A total of 119 relevés were sampled between 2015 and 2021 using the seven-degree Braun-Blanquet cover-abundance scale. They were classified by a modified TWINSPAN method. Diagnostic species were identified using phi coefficient as a fidelity measure. Detrended Correspondence Analysis (DCA) was used to determine relationships between samples, vegetation units and major gradients in species composition. Plant communities have been divided into two main groups. The first one is a west Irano-Turanian wood of Juniperus polycarpos var. seravschanica of the Pamir-Alai mountane belt. It occurs in two variants depending mainly on the aspect and precipitation. The second juniper wood type in Tajikistan is a stand of Juniperus pseudosabina. It prefers the northern slopes and north-eastern ranges of the Pamir-Alai and slightly lower elevations. Both juniper wood types are highly distinct in terms of species composition, especially in the moss layer, and have therefore been assigned to different classes: Pino-Juniperetea (Juniperetum seravschanicae) and Juniperetea pseudosabinae (Carici turkestanicae-Juniperetum pseudosabinae). The main factors determining the species composition of the studied associations are latitude, growing season precipitation, annual range of air temperature and precipitation of coldest quarter. Our study has shown that there are two very distinct vegetation types of the juniper wood groves in Tajikistan, which reflect the main phytogeographical division between the provinces of Turkestan and Central Asia.

Opis:
The purpose of the described research was an attempt to estimate the leaf area index (LAI) parameter describing the structure of the vegetation based on the Landsat 5TM satellite imagery and field measurements made with the use of an optical plant canopy analyzer. The study was carried out in north-eastern Poland in the Biebrza river valley within the boundaries of the Biebrza National Park during the growing season of the year 2007. There were 13 spectral indices given in the literature known to be correlated with the LAI. The highest coefficient of determination and the highest correlation coefficient were obtained for the normalized difference vegetation index (NDVI) and the soil adjusted vegetation index (SAVI) indices for the wetland areas in the Biebrza river valley. The field measurements of the leaf area index and its spatial representation on satellite image show that the vegetation of natural river valleys is characterized by high spatial and seasonal variability. The study of the LAI on such large natural areas that are extensively used also requires knowledge of the methods of land use and the application of individual agrotechnical measures.

Opis:
The vegetation cover of the Głuszec stream valley was investigated. The article presents a list of 294 recorded species of vascular plants from 65 families and, also, 47 plant associations from nine classes, from three dynamic vegetation circles: Carici elongatae-Alnetum, Fraxino-Alnetum and Querco- -Ulmetum minoris. Six types of vegetation complexes were documented. Their phytocoenotic structure was shown in a table containing relevés made in sigmassociations. The preliminary results of research on the dynamics of Dactylorhiza incarnata population, occurring in one of meadow complexes, were presented. The Głuszec stream valley was recognised as the region of exceptional natural plant cover within the city of Poznań and proposed to be incorporated into the green network of the Poznań Agglomeration. The valley was also included in the agri-environmental program. An active protection of grassland ecosystems is achieved by adhering to the requirements of this program and additional recommendations of an expert botanist.

Opis:
On the basis of the obtained expeditionary data, the authors performed a comprehensive analysis of the ecosystems’ modern transformation in the studied area. In the course of the analysis, the authors found that at the present stage there have been quantitative changes (depletion of natural resources) in used landscapes, along with them, there are changes in qualitative characteristics (accumulation of resources). Now, against the background of vegetation and soil degradation, ways of their restoration are observed. New combinations of degraded and self-recovering ecosystems have emerged. Based on the analysis of the current state of different ecological systems and their relationships, the authors determined the possibilities of the dynamics of their combinations functioning by stages. This will make it possible to give a more reliable forecast of the ongoing processes in the ecosystems of the Republic of Kazakhstan.

Opis:
W rolniczym krajobrazie ważną funkcję pełnią powierzchnie wyłączone z użytkowania, czyli siedliska marginalne (wyspy środowiskowe). Są to zarówno obiekty linearne: miedze, śródpolne skarpy, brzegi cieków i lasów, pobocza dróg i polne drogi, jak i wyspy ekologiczne: oczka śródpolne, małe torfowiska, niewielkie zadrzewienia, ekstensywnie użytkowane łąki i murawy. Obiekty te charakteryzują się znacznie większą różnorodnością biologiczną niż otaczające je pola lub intensywnie użytkowane łąki. Można je uznać za ostoje roślin i zwierząt. Florę gminy Uniejów tworzą 623 rodzime i trwale zadomowione gatunki roślin naczyniowych. Na siedliskach wyłączonych z użytkowania stwierdzono 319 gatunków. Najbogatszymi florystycznie obiektami są pobocza dróg, które zasiedla 128 gatunków, a najuboższymi – niewielkie płaty ciepłolubnych muraw z 75 taksonami. Najwyższy wskaźnik naturalności (64,4%) cechuje florę małych mokradeł, a najniższy – flory miedz śródpolnych i poboczy dróg. Wyspy środowiskowe mogą być chronione w formie użytków ekologicznych oraz w ramach systemu rekompensat finansowych, zachęcających rolników do ich utrzymywania w zakresie programów rolnośrodowiskowych.
Marginal habitats (ecological islands), i.e. areas of land isolated by natural or artificial means from the surrounding land and not in agricultural use, fulfil an important function in agricultural landscape. They include linear objects, such as balks, boundary strips, paths and side spaces, forest edges, or river and stream banks, as well as non-linear objects, such as small peatbogs, clumps of trees, or extensively used meadows. Such objects are characterized by much greater biological diversity than the surrounding fields or intensively used meadows. They can be regarded as refuge for plants and animals. Marginal habitats can be protected in the form of ecological grounds or under the system of financial compensations, providing incentives for farmers to maintain them.

Opis:
In spite of modern trends in the development of the eastern Polesye flora, the relict have been preserved in the aquatic ecotopes of Europe, including eastern Polesye. The paper highlights the peculiarities of the distribution in the region of three aquatic Tertiary relics preserved by the Bern Convention. According to the results of a field research, the degree of a modern rarity of the aquatic relict species in eastern Polesye was established, in particular, a very rare species (Aldrovanda vesiculosa), a moderately rare species (Trapa natans) and a relatively rare species (Salvinia natans). The current distribution of these relict species in the region has been positively affected by the increase in the values of maximum temperatures and isotherms of the summer months. A negative impact is made by the abrupt changes in the hydrological regime and the growth of anthropogenic eutrophication of reservoirs. Aldrovanda vesiculosa eliminates with minor changes in living conditions; Salvinia natans is the most tolerant to anthropogenic factors, but shows annual fluctuations in numbers; Trapa natans is stable distributed and has a tendency to expanding of its populations. The relics are the dominants of the Salvinio–Spirodeletum (polyrrhizae), Lemno Utricularietum vulgaris, Spirodelo–Aldrovandetum vesiculosae, Trapetum natantis and Trapо–Nymphoidetum (peltatae) communities.

Air pollution in our surrounding is increasing day-to-day due to urbanization and industrialization. In this report the effect of air pollution on vegetation was investigated. Polluted and non-polluted sites were chosen and comparative study was done on the climatic factors, level of pollution and their effects on vegetation of these areas. Plants found in the polluted area showed stunted growth, chlorosis and scars on stem and leaves. These were the effect of obnoxious gaseous elements which were found in elevated level in the polluted area. Pollen viability of the plants growing in the polluted area was lower than that of non-polluted site. This study portrays a clear view of adverse effects of air-pollution on plants.

Opis:
Multiproxy data (pollen, plant macrofossils, 14C dates and loss-on--ignition measurements) obtained from the Bevardis and Verpstinis lakes in the Labanoras area (East Lithuania) were used to reconstruct a vegetation history and to reveal major environmental features during post-glacial time. Biostratigraphical data indicates ongoing sedimentation in Verpstinis Lake since the final stages of the AllerÝd. The pollen data shows that Pinus-dominated forest flourished during the AllerÝd, while the Younger Dryas was characterized by open shrub/herb/grass vegetation with highly abundant Juniperus. These are evidences of severe climatic conditions in the area. The 14C data suggests that sedimentation started in Bevardis Lake with the onset of the Holocene. Picea immigrated into the Verpstinis Lake surroundings in the Late Glacial, just before 11 500 cal yr BP according to the palynological evidence. The expanding deciduous taxa, e.g., Corylus (ca. 10 200-10 000 cal yr BP), Alnus (8200-8000 cal yr BP), and broad-leaved species with Ulmus (ca. 10 000 cal yr BP), Tilia (7700-7400 cal yr BP) and Quercus (5200 cal yr BP), formed a dense mixed forest where Picea appeared at 7300-6800 cal yr BP. Both diagrams show only negligible human impact. It seems that natural factors were responsible for the formation of vegetation cover and environment in the study area throughout the post-glacial.

Celem pracy było zbadanie wpływu promieniowania ultrafioletowego (UVC) na wzrost, rozwój i plonowanie roślin ziemniaka (Solanum tuberosum L). Obiektem badań były 132 rośliny ziemniaka średnio późnej odmiany Jelly, których wegetacja przebiegała pod osłoną tunelu foliowego. W doświadczeniu wykorzystano autorskie stanowisko do naświetlania materiału roślinnego ultrafioletem. Sadzeniaki przed umieszczeniem w glebie naświetlono promieniami ultrafioletowymi przez czas 1, 10, 60 min przy stałej odległości promiennika UVC od dna komory 0,7 m. W trakcie okresu wegetacji oceniano tempo wschodów, kwitnienia i zamierania łętów, określano długość i liczbę łodyg, a po zbiorze określono strukturę plonu każdej rośliny. Stwierdzono istotny wpływ ultrafioletu na rozwój części nadziemnej roślin ziemniaka. Obliczenia statystyczne wykonano przy założonym poziomie istotności α=0,05.
The aim of the paper was investigation of ultraviolet radiation (UVC) impact on the growth, development and cropping of potato plants (Solanum tuberosum L). 132 potato plants of medium late cultivar Jelly, vegetation of which was carried out under the plastic tunnel constituted the research object. The author's stand for irradiation of plant material with ultraviolet was used. Seed potatoes, before placing them in the soil, were radiated with ultraviolet rays for 1,10,60 minutes at the constant distance of UVC radiators from the bottom of a chamber - 0.7 m. During vegetation period the rate of germination, flowering and withering of haulms, length and number of stems was determined and after harvesting the yield structure of each plant was determined. Essential impact of ultraviolet on the development of aboveground part of potato plants was reported. Statistical calculations were carried out at the assumed level of significance α=0.05.

Na terenie Równiny Wełtyńskiej występują silne wiatry. W związku z tym wszelkie zadrzewienia, zmniejszające ich siłę, powinny być chronione lub chociażby nie niszczone. Celem badań było określenie zróżnicowania aktualnego stanu szaty roślinnej śródpolnych zadrzewień grupowych w zależności od gatunku dominującego w drzewostanie. W latach 1996-2001 przeprowadzono prace terenowe na gruntach ornych Równiny Wełtyńskiej - badano skład gatunkowy zadrzewień grupowych. Na niewielkiej powierzchni tych obiektów (średnio 0,019 ha) oznaczono 144 gatunki roślin naczyniowych (w tym 20 drzew i 26 krzewów). Spośród drzewostanu najliczniejsze były zadrzewienia powstałe z nasadzeń z: brzozą brodawkowatą (Betula pendula Roth), jesionem wyniosłym (Fraxinus excelsior L.) oraz topolą osiką (Populus tremula L.) - 54%. Najwięcej zadrzewień znajdowało się w pobliżu dróg (77%), rzadziej stromych zboczy (20%), a sporadycznie w wilgotnych zagłębieniach terenu (3%). Wśród 16 stwierdzonych zbiorowisk dominowała roślinność łąkowa (43% - Arrhenatheretum elatioris, Sileo otitis-Festucetum, zbiorowisko z perzem właściwym (Elymus repens), kostrzewą łąkową (Festuca pratensis), barszczem syberyjskim (Heracleum sibiricum) i Poa pratensis-Festuca rubra) oraz nitrofilna (40% - Anthriscetum sylvestris, Convolvulo arvensis-Agropyretum repentis, Urtico-Aegopodietum podagrariae, Lamio albi-Conietum maculati, zbiorowiska z ostrożniem polnym (Cirsium arvense), pokrzywą zwyczajną (Urtica dioica), rzadziej szuwarowa (13% - Phalaridetum arundinaceae, Phragmitetum australis), a sporadycznie zaroślowa (9% - zbiorowisko z trzcinnikiem lancetowatym (Calamagrostis canescens) oraz z niecierpkiem pospolitym (Impatiens nolitangere). Roślinność łąkowa i nitrofilna była najliczniejsza, szczególnie zbiorowisko z perzem właściwym (Elymus repens) - 24% - i Anthriscetum sylvestris - 22%.
Strong winds blow on Wełtyń Plain and for this reason every woodlot that may decrease the wind power should be protected, or at least not destroyed. The main goal of the study was to recognize present floral and phytosociological differentiation of the mid-field woodlots in relation to the dominating species in tree stand. In 1996-2001 arable lands of Wełtyń Plain were studied to analyse floral composition of woodlots. 144 species of vascular plants were found on the small areas (average area was 0,019 ha) of mid-field woodlots. Common birch, European ash and aspen poplar were most frequent in tree stands (54%). Most woodlots were of anthropogenic origin (except for woodlots with Alnus incana, A. glutinosa and some with Populus tremula). Roadside woodlots were most common (77%) and those near the steep escarps - rather rare (20%). Woodlots in wet depressions constituted 3% of analysed woodlots. There were 16 communities, including 43% of meadow vegetation (e.g. - Arrhenatheretum elatioris, community with Elymus repens), 40% of nitrophilous plants (e.g. - Anthriscetum sylvestris, Urtico-Aegopodietum podagrariae), 13% of marshlands (Phalaridetum arundinaceae, Phragmitetum australis) and 9% of shrubs (community with Calamagrostis canescens, Impatiens nolitangere). Meadows and nitrophilous communities were most frequent, especially the community with Elymus repens and Anthriscetum sylvestris.

Opis:
Considering plant-to-soil pathways, decomposition of vegetative fluxes such as litter and litterfall is one of the important processes that adjust the carbon cycle and nutritional elements in the formation of a forest's organogenic horizon. However, there is little information available on this subject, and the fractional structure (amount, type and interrelation) of organic matter also seems to receive little attention. Using 7 different vegetative samples, a field study was performed over 3 years to find the relation between phenolics content and mass losses in the subarctic region (N66° and E31°). In addition, climate effects on this relation were investigated. The data obtained from this field study testify that (i) an intensive loss of organic matter occurred in active parts of various litterfalls and (ii) leached phenols were related with mass losses (decomposition rates) of vegetative fluxes (litterfalls and litters) to the soil. The statistic analysis suggests that (iii) total mass losses of samples (except litter) were connected with both the temperature sum and the precipitation sum, and (iv) phenolics losses also had a similar trend in different kinds of litterfall.
