Opis:
Modern multifunctional forest management needs indicators showing the state of forest environment. Commonly used solution is monitoring of the abundance of species with specific environmental requirements. This paper analyses the possibility of use of the biggest European woodpecker (Dryocopus martius) as forest management quality indicator. The black woodpecker resides in all types of forest sites. The species prefers big thick trees as a nest trees, its cavities were mainly made in birches Betula sp. in Western and Southern Europe, Scots pines Pinus sylvestris in Middle and Eastern Europe and aspens Populus tremula in Northern Europe. The black woodpecker, excavating large−sized breeding cavities, is defined as a key species due to the creation of breeding sites for large secondary cavity−nesters. Because of the breeding requirements, black woodpecker can also be treated as an umbrella species for organisms associated with old trees. The way of feeding of that species shows a strong connection with the availability of dead wood. The black woodpecker is a sedentary species, which means that it is highly depended on the structure of the forest and quickly responds to changes caused by forest management. Because of the habitat requirements and relationships with other species, as well as the wide geographical range, it is a good indicator species for multifunctional suitable forest management. It can also act as a keystone species for secondary cavity nesters and umbrella species for organisms associated with old, dying trees.

Opis:
The research investigates the possibility of applying Sentinel-2, PlanetScope satellite imageries, and LiDAR data for automation of land cover mapping and 3D vegetation characteristics in post-agricultural areas, mainly in the aspect of detection and monitoring of the secondary forest succession. The study was performed for the tested area in the Biskupice district (South of Poland), as an example of an uncontrolled forest succession process occurring on post-agricultural lands. The areas of interest were parcels where agricultural use has been abandoned and forest succession has progressed. This paper indicates the possibility of automating the process of monitoring wooded and shrubby areas developing in post-agricultural areas with the help of modern geodata and geoinformation methods. It was verified whether the processing of Sentinel-2, PlanetScope imageries allows for reliable land cover classification as an identification forest succession area. The airborne laser scanning (ALS) data were used for deriving detailed information about the forest succession process. Using the ALS point clouds vegetation parameters i.e., height and canopy cover were determined and presented as raster maps, histograms, or profiles. In the presented study Sentinel-2, PlanetScope imageries, and ALS data processing showed a significant differentiation of the spatial structure of vegetation. These differences are visible in the surface size (2D) and the vertical vegetation structure (3D).

Opis:
T he paper deals with the succession of basidiomycete macrofungi on abandoned farmland. T T he research was carried out in the unique complex of old fields of different age located on the southwest edge of the Białowieża old-growth forest (NE Poland). T T hese lands undergo spontaneous secondary succession leading to formation of a continental fresh pine forest. Regular observations of basidiomata in 16 permanent plots (11 plots of 1000 m2, 5 plots of 400 m2) representing initial, optimal and terminal stage of vegetation development from psammophilous grassland to a pine forest with 100-year-old tree stand were conducted for three years. Soil and vegetation analyses were also carried out as well as quantitative examination of ectomycorrhizae in root samples. T he series yielded 300 species of macromycetes (including 6 collective taxa) found in permanent plots plus 18 species outside the plots. T T he species composition, spatial distribution of sporocarps, and quantitative structure of fungal communities changed along the successional gradient. Increasing diversity of fungi resulted from persistence of species typical of open areas and species associated with younger trees, as well as accumulation of species associated with older trees and more developed stands. Some species typical of younger phases were replaced with species arriving later in the chronosequence. Species usually occurred long before and after attaining maximum abundance and frequency. Species associated with certain periods of vegetation development could be distinguished, as well as species accompanying the phytocoenoses regardless of their developmental stage. Patterns in structural changes of the fungal community, e.g., in number of species, abundance, frequency and production of carpophores, could also be recognised. T T hey were different in ectomycorrhizal and in saprotrophic fungi. T T he occurrence of the former was influenced mainly by the presence of symbiotic trees and their age, stand structure and soil properties, while occurrence of the latter was affected by microclimatic factors and by diversity of accessible substrates. Changes in fungal communities were consistent with vegetation changes, but were also specific to this group of organisms.

Opis:
The role of image classification based on multi-source, multi-temporal and multi-resolution remote sensed data is on the rise in the environmental studies due to the availability of new satellite sensors, easier access to aerial orthoimages and the automation of image analysis algorithms. The remote sensing technology provides accurate information on the spatial and temporal distribution of land use and land cover (LULC) classes. The presented study focuses on LULC change dynamics (especially secondary forest succession) that occurred between 1974 and 2010 in the Błędów Desert (an area of approx. 1210 ha; a unique refuge habitat – NATURA 2000; South Poland). The methods included: photointerpretation and on screen digitalization of KH-9 CORONA (1974), aerial orthoimages (2009) and satellite images (LANDSAT 7 ETM+, 1999 and BlackBridge – RapidEye, 2010) and GIS spatial analyses. The results of the study have confirmed the high dynamic of the overgrowth process of the Błędów Desert by secondary forest and shrub vegetation. The bare soils covered 19.3% of the desert area in 1974, the initial vegetation and bush correspondingly 23.1% and 30.5%. In the years 2009/2010 the mentioned classes contained: the bare soils approx. 1.1%, the initial vegetation– 8.7% and bush – 15.8%. The performed classifications and GIS analyses confirmed a continuous increase in the area covered by forests, from 11.6% (KH-9) up to 24.2%, about 25 years later (LANDSAT 7) and in the following 11 years, has shown an increase up to 35.7% (RapidEye 2010).

Opis:
Zespół Alopecuretum pratensis (Regel 1925) Steffen 1931, występujący na terenie Parku Krajobrazowego "Podlaski Przełom Bugu", scharakteryzowano na podstawie 50 zdjęć fitosocjologicznych, wykonanych metodą Brauna-Blanqueta. Każde zdjęcie opisano względnym pokryciem gatunków: charakterystycznych dla klasy; charakterystycznych dla siedlisk wilgotniejszych lub siedlisk suchszych; synantropijnych oraz drzew i krzewów. Obliczono również następujące wskaźniki Ellenberga: L - wskaźnik świetlny, F - uwilgotnienia, R - odczynu gleby, N - zawartości azotu w glebie. Parametry te syntetycznie opisano metodą GGE biplot (ang. "Genotype and Genotype-by-Environment interaction effects"). Wykres typu biplot umożliwił wytypowanie grupy niezaburzonych płatów zespołu Alopecuretum pratensis oraz płatów zaburzonych. Te ostatnie to albo fitocenozy występujące w siedliskach przesuszonych, w których odnotowano równocześnie zwiększony udział gatunków synantropijnych, albo fitocenozy zlokalizowane w siedliskach wyraźnie wilgotniejszych. Większość płatów zespołu Alopecuretum pratensis, zanotowanych na terenie Parku "Podlaski Przełom Bugu", wykształciła się w warunkach siedliskowych zbliżonych do optymalnych dla tego syntaksonu i została zaliczona do postaci niezaburzonej, co świadczy o jego dobrej kondycji. Metoda GGE biplot okazała się przydatna do oceny stanu zespołu Alopecuretum pratensis oraz określenia kierunków jego zmian.
The Alopecuretum pratensis association (Regel 1925) Steffen 1931 in the Bug Ravine Landscape Park was described by 50 relevčs with the use of Braun-Blanquet method. The aim of this study was to define the conditions and symptoms of degeneration of Alopecuretum pratensis. Each of the relevčs was described by the relative cover of: characteristic species of Molinio-Arrhenatheretea class, characteristic species of wetter and drier habitats, synanthropic species, tree and shrub species. The Ellenberg indicators (L - light, F - moisture, R - soil pH, N - soil nitrogen) were also calculated. Above mentioned parameters were described synthetically by the GGE biplot method (Genotype and Genotype-by-environment interaction effects). The graph designated the group of undisturbed and disturbed phytocenoses of Alopecuretum pratensis. The disturbed phytocoenosis were often located in drier habitats or in markedly wetter sites. In the first case it was associated with greater participation of synanthropic species. Summing up, most of the described phytocoenoses of Alopecuretum pratenis developed in conditions close to the optimal for that syntaxon and were classified as undisturbed, which indicated their good condition in the Bug Ravine Landscape Park. Selection of appropriate parameters of examined plant community allowed the use of the GGE biplot method for assessing the state of Alopecuretum pratensis and determining the directions of its change.

Opis:
In July, 1992, fire swept through the Jelonka Reserve (52o35'33"N; 23o22'10"E). Litter, herbs layer and juniper shrubs were razed and the tree trunks of Pinus sylvestris and Populus tremula damaged, which resulted in their death the following year. Five research plots of 25 m2 each were established in the post-fire area. The species present there and their degrees of coverage were listed on the Londo scale between 1993 and 2002. The calculation of average degrees of coverage for individual populations allowed for the establishing of a chronological pattern of post-fire succession. The following findings have been made: 1) the primary function in colonization belongs to species of guerilla strategy of growth whose dormant buds survived fire underground (Holcus mollis, Calluna vulgaris and Populus tremula) or phalanx strategy of growth (Corynephoms canescens); 2) the dominants of the initial succession stage are perennial grasses, not therophytes; 3) the spatial pattern of succession is influenced by the occurrence of H. mollis or C. canescens in a particular location; 4) the initial stage terminates with the occurrence and further growth of C. vulgaris clumps; the post-fire succession in the Jelonka Reserve attained a brushwood stage faster in comparison to secondary succession, formerly triggered by the cessation of cultivation on arable land.

Opis:
Agents causing damage to plant organisms like drought, folivore feeding, fungal pathogens, ground frosts have no significant effect on tree mortality if they occur individually, however their concurrent occurrence may lead to mass dieback of trees on a local scale. Changes in cell biochemistry of trees under the impact of stress factors enable development of fungal infections or facilitate insect attacks. This study presents examples of interactions between physiological changes (e.g. in production of enzymes, phenolic compounds, etc.) determining host plant resistance and pathogen or pest responses to these changes.

Opis:
Fires that are one of the most classic disturbance of plant communities have had a great impact on the development of Scots pine communities. Restoration of vegetation disturbed by fire in this type of community starts almost immediately after disturbance. The intensity of fire significantly influences the future composition of vascular plant species and also the rate of change. The aim of the study was to describe the effect of intensity of the surface fire on the forest floor vegetation response and to preliminary attempt to characterize the syndynamic processes occurring after the disturbance. The research was conducted in Scots pine forest Peucedano−Pinetum in the Kampinoski National Park (central Poland). We established 45 permanent study plots, including 17 not burnt (control) and 28 burnt ones. Each plot covered area of 100 m². On each plot at first we separated the areas which were not burnt, surface burnt and characterized by complete burnout of the organic horizon of the soil. Than we measured the thickness of this horizon. Additionally the volume of organic matter burnt within each plot was calculated. Vegetation was sampled using Londo scale in the year of fire (2015) and the year after (2016). We used DCA ordination and UPGMA classification methods. Recorded species were divided into forest and non−forest groups and additionally for trees and shrubs, and the others, containing dwarf shrub, herb, bryophyte and lichen species. The linear regression method was used to estimate the relationship between measured parameters, vegetation change and changes in the species richness of distinguished groups. Two processes of vegetation reaction were observed. The first was classified as regeneration and occurred within surface burnt plots. Its characteristic feature included the higher increase in forest species richness than in case of non−forest species. The other process was defined as secondary succession alike. It occurred on plots with highest burnout of soil organic matter horizon. The increase of richness of non−forest species predominated within it. The change between two processes is smooth and depends on the participation of area with complete burnout of soil organic horizon within plot. The results show, that more than one process of recovery of community can occur in the same site and it depends especially on the proportion of soil organic horizon area burnout.

Opis:
The research concerned the evaluation of the soil seed bank and herb layer diversity in the 60−year old secondary oak forest growing in the Kozubowski Landscape Park (Nida Basin, southern Poland). The aim of the studies was to determine the diversity, similarity and species structure of herb layer and soil seed bank within plots situated at different distances from the forest edge as well as to discuss the obtained data with the results of analogous research which were conducted in the natural oak forest in Białowieża (north−eastern Poland). 12 plots 20×20 m were situated in three zones from edge to the centre of the forest (P, S and L; fig. 1). A total of 134 species of vascular plants were recorded in the analysed herb layer (4800 m2). It was found that in the plots closest to the forest edge, both the Shannon’s diversity index and the average density of the herb layer species were significantly higher than on these located deeper in forest (fig. 2, 3). The soil seed bank contained a total of 2820 seeds belonging to 45 species. The density of the seed bank ranged from 1406/m2 (P) to 1061/m2 and 1057/m2 (S and L, respectively). The seed bank species richness showed a constant decrease from zone P to L (fig. 4). The Sörensen species similarity coefficient between the herb layer and the seed bank for the entire forest was 0.43. Although nearly 90% of the seeds of the whole bank belonged to the species present in the herb layer, the species structure of the above ground vegetation was clearly different from that recorded in the bank. It was found that over 66% of all seeds in the bank belonged to Poa nemoralis. A comparative analysis of the studied oak forest and natural oak forest of Białowieża showed: a similar number of forest species in herb layer per 100 m2, similarly high proportion of ancient forest species in the herb layer, much lower species richness of the seed bank as well as its density in the secondary forest. Our results also point to several times lower values of H’ Shannon−Wiener’s biodiversity index, both in the herb layer and the seed bank in comparison to the undisturbed Białowieża oak forest.

This study present species composition and potential of litter on carbon and nitrogen return in secondary mixed deciduous forest after shifting cultivation. The dominant species of trees were Haldina cordifolia, Albizia odoratissima and Lagerstroemia duperreana. The Important Value Index (IVI) values of trees were 132.91, 17.78 and 14.22, respectively. The pattern for the decomposition coefficients (k) was highest in the wet period (May–September) and lowest in the dry period (October–April). The carbon and nitrogen return patterns increased in the dry period (October– April) and decreased in the wet period (May–September). Carbon and nitrogen loss in the decomposing litter continually decreased during the decomposition process from the initial levels, with a final relatively rapid release in the wet period. Results from this study was understanding of community composition, litterfall production and litter decomposition for understanding potential of secondary mixed deciduous forest for balancing carbon for mitigating greenhouse gas effect in the local area.

Opis:
Ectomycorrhizal (ECM) fungi and their symbiotic associations with forest trees are among major drivers of key ecosystem functions such as carbon and nitrogen cycling, plant nutrient and water uptake from soil, plant-plant facilitation/competition and diversity regulation via common mycorrhizal networks. Through their functional traits and interactions with both abiotic and biotic environment, they also significantly affect the process of open land colonization by trees as well as vegetation succession coupled with soil and ecosystem development. Here we review the role of ECM fungi in the early primary and secondary succession following major anthropogenic disturbances. Based on the examples of mine spoils and post-agricultural lands, we demonstrate key ecosystem services provided by ECM fungi in the processes of forest restoration. We point out ecological mechanisms and adaptations which underpin ECM fungal community successional interactions, particularly life histories, dispersal, spatial structure, host preferences, and sensitivity to environmental filters. We emphasize the need of better understanding the role of ECM fungi in the forest restoration practice as it seems crucial for afforestation success and biodiversity rehabilitation. Thus, ectomycorrhizal traits should be a prime consideration in afforestation and carbon sequestration polices, sustainable forest management and biodiversity conservation practices.

Opis:
Characteristic features of European woodland include both a reduction in natural forest areas and an increase in former agricultural areas occupied by secondary woodland. The management of these areas is challenging in terms of nature conservation, agricultural and forestry management and policy. The aim of our study was to reconstruct the history and to document the current tree stand structure for a secondary oak-beech woodland in Hungary. Towards the end of the 1800s, this area which was once almost completely occupied by a continuous forest, had been transformed into a wood-pasture. As a result of its gradual abandonment, the closed forest stand of the pasture increased from 10 to 52% between 1963 and 2005. The most characteristic feature of this woodland is the abundance of large trees. Globally, the number of large and ancient trees is rapidly diminishing. Therefore preserving and maintaining such areas, where large trees could live, is an essential management task.

The size and diversity of seed banks was studied with the seedling emergence method. Species abundance (i), density (ii), number of species from different biological groups (iii) and distribution and mean LI value (iv) were analysed as the function of fallow land age. It was found that: (i) species diversity, number of species and ln of density are linear declining function of the fallow land age; (ii) for approx. 25 years the share of diaspores of identified species groups has been relatively similar. Seed banks of 40-50-year-old fallow lands are dominated by Calluna vulgaris, while the seed bank of the old fresh coniferous forest is dominated by dicotyledonous perennials and grasses; (iii) within the first 50 years of succession the persistence of seed banks measured by the Longevity Index increases gradually.

Opis:
Transformacja ustrojowa, jaka miała miejsce w Polsce ponad 20 lat temu, a także przystąpienie naszego kraju do UE, pociągnęły za sobą liczne zmiany, m.in. w rolnictwie (likwidacja PGR, porzucanie upraw roli, wolny rynek zbytu czy wzrost konkurencyjności producentów) oraz w gospodarce prowadząc do głębokich przemian społeczno – ekonomicznych. Skutki tych transformacji zauważalne są także w przestrzeni rolniczej, najczęściej w przemianach krajobrazu. Zmiany te mają zazwyczaj charakter procesu wtórnej sukcesji leśnej zachodzącej na działkach rolnych. Tempo wkraczania i rozszerzający się z roku na rok zasięg terytorialny wtórnej sukcesji, najczęściej nie jest przedmiotem zainteresowania odpowiednich agencji lub urzędów. Technologią, która może wspomagać określanie zmian ilościowych (powierzchni, liczby działek rolniczych podlegających zmianom) i jakościowych (typ sukcesji – zbiorowiska roślinnego) przebiegających w krajobrazie - jest lotnicze skanowanie laserowe (ang. Airborne Laser Scanning; ALS). Prezentowane w pracy badania objęły 79.87 ha gruntów rolnych wsi Tuklęcz (gm. Rytwiany, powiat Staszów, woj. świętokrzyskie). W pracach wykorzystano dane EGiB (PODGiK w Staszowie) oraz dane ALS w postaci 2 zestawów chmur punktów ALS o gęstości: 2 pkt/m2 (RZGW Kraków; XI.2009r.) oraz 4 pkt/m2 (ISOK; XI.2012r.). Detekcję wtórnej sukcesji leśnej przeprowadzono stosując 4 warianty różniące się wysokością roślinności (odpowiednio: 0.4m, 1.0m, 2.0m oraz 3.0m ponad wygenerowanym NMT). Uzyskane wyniki wskazują, iż w każdym wariancie, na 50% liczby działek z użytkiem rola („R”; 60.54% całego obszaru) koncentrowało się ponad 70% wtórnej sukcesji leśnej. W zależności od jej wysokości nad gruntem, pokrywała ona od 61.05% do 31.38% klasoużytku „R” oraz od 67.03% do 34.93% pastwisk („Ps”) co świadczy o dynamicznych przemianach zachodzących na tym terenie. Cykliczne pozyskiwanie danych ALS w odpowiednich porach roku (zestaw danych ISOK wykazywał znaczący brak informacji o zadrzewieniach liściastych gatunków) bądź też stosowanie alternatywnych technologii (np. stereo-matching ze zdjęć lotniczych czy zobrazowania radarowe), stwarza szanse na zarządzanie i monitorowanie zmian zachodzących na obszarach rolniczych w Polsce. Jest to istotne ze względu na sporządzanie miejscowych planów zagospodarowania przestrzennego czy też wdrażanie Krajowego Programu Zwiększania Lesistości (KPZL), zakładającego osiągnięcie poziomu 30% lesistości w Polsce w roku 2020 oraz 33% w roku 2050. Nie należy zapominać o ogromnym potencjale biomasy zgromadzonej na obszarach wtórnej sukcesji nie ujętej w bazach EGiB czy LMN PGL Lasów Państwowych a stanowiącej istotny czynnik w dobie handlu emisjami CO2 czy wdrażania dyrektyw UE o energiach odnawialnych.
Dynamic economic and social changes taking place for the past 20 years in Poland, effects often of such loss of extensive agriculture and abandonment of agricultural activities particularly on small and narrow plots, usually on the soils of poor grading. Even before the Polish accession to the EU, set-aside and fallow areas cover approx. 2.3 million ha (in 2002), but in subsequent years the area drastically decreased from 1.3 million ha (in 2004), by 1.0 million ha (2005) to 0.4 million hectares (2011). As a result of cessation of mowing meadows, grazing pastures and agricultural measures, we can observed the phenomenon of secondary forest succession (plant communities of a forest properties) leading to changes in land use and land cover classes structure. Recording changes in the agro-forestry space, update reference registers of the land and building (EGiB) and control granted to farmers subsidies (direct EU payments) requires an efficient and automated technology acquisition, processing and analysis of spatial data. In addition to the used by ARiMR (in the LPIS system) vector data and aerial orthophotomaps, there is still a need to strengthen the decision-making process such as update of current ranges of land-use classes. One of the GI technologies that could be a real breakthrough is the Airborne Laser Scanning (ALS). The study area cover 137.17 ha in the village Tuklęcz (commune Rytwiany, Staszów County, Świętokrzyskie Voivodeship). The EGiB geodata came from PODGiK in Staszów. They were two ALS point cloud data sets: one provided by the RZGW in Krakow (from airborne campaign Nov. 2009; density ~2 pts/m2) and the second from ISOK project (Nov. 2012; density ~4 pts/m2). The Terrasolid and FUSION (USDA Forest Service) and ArcGIS Esri software were used in the study. Detection of vegetation was carried out in 4 variants differ in the “height above ground” of the class "succession" (thresholds: from 0.4m, 1m, 2m and 3m). The results indicate that in each scenario (variant), in the area of arable land ("R")- class (covering 60.55% of the analyzed area) were over 70% of all detected secondary forest succession polygons, covering more than 50% of agricultural land. Secondary succession occupied from 31.38% to 61.05% the land-use "R" and from 34.93% to 67.03% of the land-use Pastures’ ("Ps"), which shows the high economic transformations taking place in the area. The use of wide-scale ALS data in Poland, has been made possible by the ISOK project assuming execution to the end of 2013 for an area of about 191.000 km2 of classified ALS point cloud (cloud density: 4 pts/m2 – Standard I for agricultural areas; 12 pts/m2 - Standard II for urban areas), digital terrain model (DTM) and the digitals (topographic) surface model (DSM). In addition, the aerial photographs are obtained in the ISOK project for coloring of ALS point clouds or for orthophoto generation purpose. Observed in the years 2002 -2010 decrease by 26% the number of farms in Poland (up to 1 ha area) is some indication that the problem of abandonment of agricultural land has not yet been closed. Regular ALS campaigns or the use of alternative technologies such as stereo-matching of aerial photographs or radar technologies, it gives a good chance to manage and monitor the changes in rural areas. This retrieved data can be used in the construction of development plans of communes or management plans of Natura2000, which largely depend on properly conducted agricultural economy (Special Protection Areas - SPA) means eg mowing overgrown meadows and pastures. On the other hand, since 1995, the National Afforestation Programme (KPZL) exist, which implies achieving 30% forest cover in Poland in year 2020 and 33% in year 2050.
