    Opis:
    The calamity windstorm in November 2004 caused dramatic changes of land cover in the Tatra Mountains. The bora have destroyed then more than 12,000 ha of forest and principally affected the habitat structure in the Tatra National Park. The aim of this contribution is to quantify changes in forest fragmentation in 2000 and 2006. We present forest fragmentation maps related to the years 2000 and 2006. The CORINE Land Cover data layers CLC 2000 and CLC 2006 converted to raster format were used as the input data in the process of forest fragmentation assessment. Forest pixels were classified according to fragmentation indices measured within the surrounding landscape as the forest core, forest patch, forest edge, and perforated forest. Decrease of the compact forest areas (forest core) by about 9% was recorded. On the other side, increased percentage of disrupted forest areas was observed. Decrease of the area of the CLC forest classes (classes 311, 312 and 313) on land cover maps from 2000 and 2006 was connected with an increased number of transitional woodland/shrubs polygons (CLC class 324). These results suggest a temporary fragmentation with possible forest regeneration. On the other hand, forest destruction in the National Park facilitated the development of travel and tourism (new hotels, ski parks, etc.). An increased number of construction sites (CLC class 133) indicate that an urban sprawl associated with a permanent forest fragmentation can be also expected in the future.

    Landscape Changes
    Opis:
    Landscape and human are the constituents of the natural surroundings in which changing occurred temporally and spatially. The relationship between landscape and environment is not seen by a singular framework or a bare structure. A landscape has different functions and characteristics, when meet specific requirements, then set an ecology in giving context. Every landscape has its own scenario based upon the dimension of human and its kinship with them. Man are the ecosystem managers, the landscape features provide a road map and built human ecology. Development is occurring by landscape change, change of environment and the kinship between human and landscape, study of these phenomena provide us a theoretical framework to assess the man land relationship as is done in this case study. This paper aims to describe how, each individual in a particular environment is participating in change of the landscape. The influence of human is a magnitude of actions upon the landscape and this magnitude shape the local landscape. The paper discussed through a brightness on the dynamics of landscape change in the 21st century due to globalization and modern dimensions and presents us a complex web of human with non-human relationship of ecology, economy and history, which alter the landscape. This paper concluded a reflection of cultural values on physical environment and landscape change to build environment and human ecology.

    Opis:
    Urbanization directly affects the existing infrastructure, landscape modification, environmental contamination and traffic pollution especially if there is lack of urban planning. Recently, the rapid urban sprawl has resulted in less developed green areas and has devastating environmental consequences. This study was aimed to study the past urban expansion rates and Measure LST from satellite data. The Land use land cover (LULC) maps of years 1996, 2010, 2013, and 2017 were generated using Landsat satellite images. Four main classes i.e. water, urban, bare land and vegetation were identified using unsupervised classification with iterative self-organizing data analysis (isodata) technique. The LST from satellite thermal data can be derived from different procedures:atmospheric, radiometric calibrations and surface emissivity corrections, classification of spatial changeability in land-cover. Different methods and formulas were used in the algorithm that successfully retrieves the land surface temperature to help us study the thermal environment of the ground surface. To verify the algorithm, the land surface temperature and the near-air temperature were compared. The results showed that, From 1996-2017 urban areas increased to about considerable increase of about 48%.few areas of city also shown in reduction in LST from year 1996-2017that actually began their transitional phase from rural to urban LULC.Mean temperature of city increased averagely about 1ºC each year in the month of October. The green and vegetative areas witnessed a decrease in area while higher number of pixels increased in urban class.

    Opis:
    The trees of parks and gardens support many species, the survival of urban-dwelling species mainly bird species. Birds amongst other species provide a wide range of environmental and social functions to cities and urban dwellers. The present study aims to know bird diversity in two parks as bioindicator of automobile air pollution exposure, landscape changes and/or human interactions. The study areas were selected as per heavily-populated neighborhoods, nearby office buildings, nearby roads and continuous vehicular movements, human interactions as visitors, where high levels of human disturbance are common. The study was carried out at 2 sampling stations viz (i) Elliot park and (ii) Agri-horticulture Society. The bird species diversity was studied by qualitative and quantitative assessment. Indices were Species richness, Index of Dominance, Relative abundance, Shannon-Wiener Diversity Index and Evenness Index for birds for all selected sites were calculated using the statistical formulae. The present results as bioindicators bird species clearly indicate that the bird species are very few in numbers in both the parks. When comparison made between both the parks, it was observed less number of bird varieties (16 types) in Elliot park than varieties (9 types) more less in number in Agri-horticulture society. This study is a preliminary assessment of bird diversity but further researches are needed in relation to biochemical and genetic damage study as well as air pollution load by using instruments. In the present study it was concluded that the less numbers of birds and their different diversity indices were found a decreasing trends, though there no attempt has been made on physico-chemical properties of present air pollutants. The less number of varieties of bird species are as tolerant bioindicators, which may be due to the vehicular pollution and/or human interference and/or landscape changes due to nearby neighborhood blocks, office and residential buildings, continuous movement of vehicles etc.

    Opis:
    The article aims to identify areas of historical, cultural, and landscape values that are located in the suburban area of Warsaw and which may play an essential role in stabilizing the urban ecosystem of Warsaw in the future. Since it turns out that the most effective form of preserving these values is to take them under legal protection, the article shows good and bad practices in this area, identifying the most significant threats and indicating opportunities and scenarios worth considering for the future. Finally, the purpose of the article is to draw attention to the importance of spatial and scenic connections, emphasizing the importance of the surrounding landscape, which was once an immanent feature of, e.g. suburban estates. The hypothesis is that in the face of progressing climate change and melting natural resources, it is worth paying attention to the importance of all urban ecosystem elements, even smaller ones, because they are a component of a larger whole and are required for ecological balance. Existing resources should be strengthened and protected, and new places for protection should be sought. Such sites may be the former foregrounds, the immediate surroundings of monuments, which in the past functioned as larger compositions and should be protected as such.

    Opis:
    For the good established landscape planning landscape protection and landscape management actions have to take into consideration the actual conditions of the landscape elements. Earlier we dealt with the stability of the landscapes (Kerényi, Csorba, 1996), recently started to investigate the most important factors, which are endangers the proper functioning of the landscapes. Results are calculated for 229 microregions of the country, which are elements of the official landscape hierarchy of Hungary described in the Cadastral of Microregions of Hungary. The average size of the microregions are 100-500 km2. There are certain factors among which some have already elaborated, and others are being worked on yet. Degree of ecological fragmentation of the microregions by roads, railway lines and settlements was determined during the last year. In the case of large settlements the extent of inner parts, traffic intensities of the roads was taken into account, while in the case of railroads it was taken into consideration whether railway lines are single or double tracked. Results were purified using a weighting, where the location of the protected natural areas compared to the situation of the given settlement, roads or railroads was taken into consideration. In the calculations it was taken into account as well that the agglomeration processes of the large settlements may restrict the ecological gates and corridors of the migration of plant and animal species. From the series of maps on natural threats on microregional level, the map of the hazards of drought is presented first. The map gives a definite answer to the question, in which microregions is profitable to establish irrigation systems; and how high is the uncertainty of the rate of their utilization. Global warming, however, may modulate the map resented here remarkably in the next decades. Microregions that have been classified into transition categories with moderate or medium level of drought hazard may fall into categories of serious hazard of drought in the future. A synthesizing map has been completed by summing the seven datasets of the indicator group of natural hazards and the weighting of the subsets. Landscape planning is strongly affected by tendencies of macro economy on the present land use structure. EU agricultural policies have just started to affect strongly on Hungarian land use structure, therefore attempts have been made in order to forecast their impacts. Present Hungarian land use structure has been compared to priorities of the EU. Prospective shifts in land use structure have been determined for the 35 regions of Hungary. According to the 8-10 factors mentioned above, we shall have a detailed database to evaluate the microregions of Hungary in order to characterize the most threatened landscapes, and the most dangerous impacts on the landscape functioning.

    Badania prowadzono przez dwa sezony 1996 i 1998 roku. Mszyce odławiano metodą pułapek chwytnych Moerickego w czterech typach środowisk nieużytkowanych rolniczo, sąsiadujących z polami uprawnymi: miedzy, przydrożu, zakrzewieniach śródpolnych i skraju lasu, w trzech miejscowościach. Stwierdzono występowanie dwóch podstawowych typów przebiegu sezonowej dynamiki liczebności mszyc w środowiskach nieuprawnych krajobrazu rolniczego. Pierwszy z nich charakteryzował się występowaniem dwóch wyraźnych szczytów liczebności mszyc wiosną i jesienią oraz znacznym jej obniżeniem w okresie lata. Taki przebieg liczebności obserwowano w przypadku dominacji jednego lub kilku gatunków różnodomnych. Drugi typ charakteryzujący się wysoką liczebnością mszyc w ciągu całego sezonu wskazywał na dominację jednego lub kilku gatunków jednodomnych.

    Opis:
    large cities such as Warsaw. The functional and spatial changes in the neighbouring areas of the Polish capital perfectly illustrate what is also happening in other metropolises. Unfortunately, not only the main city itself but also the neighbouring municipalities experience investment pressure. This process consumes more and more areas and favours their irrational spatial and functional development, which has its negative environmental effects. In the face of threats that result from climate change, instead of looking for solutions that are logistically and technologically complicated, resources that are still available around large cities can be used. Undoubtedly, in addition to natural landscape areas, such areas may be agricultural areas. Instead of re-qualifying them, their potential can be used in creating an eco-resilient suburbs system, which is also the ecological base of the main city. The aim of the article is to draw attention to the condition, resources and adaptation possibilities of rural areas in the suburbs of Warsaw, which, like other large Polish cities, needs new ecological solutions. The study used the Statistics Poland (Główny Urząd Statystyczny) data and conclusions resulting from the literature review on the studied issue, as well as analysis of planning documents.

    Opis:
    Long-term territory sustainability is an essential prerequisite for its utility properties. The given principle applies universally. Its importance was enhanced especially in the industrial landscape and industrial agglomerations. Prerequisite for the sustainability of the area is balanced state of aquatic ecosystems, their protection and recoverability in different natural cycles. The Czech Republic is dependent on their own resources of surface and groundwater due to the fact that a relative roof of Europe does not have any significant water inflow into its territory from neighboring countries. With the changing climatic conditions around the world including Europe we can expect at least a number of decades to a lack of water to a different technological or energy utilization. Restrictions on the amount of water for implementation are reflected in industrial agglomerations necessary reduction in water consumption, at least periodic character. The given condition must be prepared by the infrastructure that is already in the preventive phase development scenarios of solutions, depending on the potential threat of water scarcity in the subject region. The following article deals with this issue in question not only in terms of natural hazards, but also in terms of what the potential risks creating industrial landscape on aquatic ecosystems and suggests what means and ways to minimize threats to make them acceptable in the trend of long-term state environmental sustainability.
    Długoterminowa stabilność terenu jest warunkiem koniecznym jego wykorzystania. Zasada ta ma znaczenie uniwersalne. Znaczenie stabilności wzrosło szczególnie w krajobrazie przemysłowym i aglomeracjach przemysłowych. Warunek wstępny do zrównoważonego rozwoju obszaru jest zrównoważony stan ekosystemów wodnych, ich ochrona i możliwość odzyskania wody w różnych cyklach naturalnych. Republika Czeska jest uzależniona od własnych zasobów wód powierzchniowych i podziemnych ze względu na fakt, że nie ma znacznych dopływów wody na jej terytorium z sąsiednich krajów. Wraz ze zmieniającymi się warunkami klimatycznymi na całym świecie w tym w Europie możemy spodziewać się przynajmniej kilku dziesięcioleci niedostatku wody do wykorzystania technologii lub energii. Ograniczenia ilości wody do konsumpcji znajdują odzwierciedlenie w koniecznej redukcji ilości zużywanej wody w aglomeracjach przemysłowych. Infrastruktura musi zostać przygotowana na możliwe ograniczenia, w zależności od potencjalnego zagrożenia niedoborem wody w badanym regionie. W artykule omówiono tę kwestię nie tylko pod kątem zagrożeń naturalnych, ale także pod względem potencjalnego ryzyka tworzenia krajobrazu przemysłowego w ekosystemach wodnych. Przedstawiono środki i sposoby minimalizowania zagrożeń, aby były akceptowalne w aspekcie długoterminowej równowagi środowiskowej państwa.

    Opis:
    In the Powidzki Landscape Park, there are 150 peatlands of a total area of 1,250.2 ha. On its edge, brown coal strip mines are in operation, causing deep land drainage that resulted in a drastic (up to 5 m) lowering of the water table in lakes and accelerated peatland disappearance. To determine the extent of the process, a comparison was made of the types of surface soil layers and their ash content in 20 peatlands determined in 1957–1965 and in 2017. They are located in the farmland lying the closest to the strip mine, Jóźwin IIB, and in woodland lying further away. The results were compared with those for a peatland in Skulsk, which was not affected by the negative impact of the strip mine. Fen peat, occurring there about 55 years ago has largely turned into grainy moorsh. In the 20–50 cm layer, an ash content has grown almost twofold, while in part of the peatlands organic soils have changed into mineral and organic-mineral ones. The greatest changes have occurred in the farmland. In all Park peatlands, grasslands have contracted threefold, while the area of forests and woodlands has grown fivefold. Today, about 10% of the peatland area is taken up by arable land of which there was none before.
    W Powidzkim Parku Krajobrazowym znajduje się 150 torfowisk o obszarze 1250,2 ha. Na jego obrzeżu prowadzona jest odkrywkowa eksploatacja węgla brunatnego powiązana z głębokim odwodnieniem terenu. Spowodowała ona drastyczne obniżenie lustra wody (do 5,0 m) w istniejących tu jeziorach i przyśpieszyła proces zanikania torfowisk. W celu ustalenia jego zakresu porównano określone w latach 1957–1965 i w 2017 r. rodzaje i popielność powierzchniowych warstw gleby w 20 torfowiskach. Leżą one najbliżej odkrywki Jóźwin IIB położonym regionie rolniczym i w dalej położonym regionie leśnym. Wyniki porównano z torfowiskiem w Skulsku, na które kopalnia negatywnie nie oddziałuje. Występujące ok. 55 lat temu torfy niskie w większości przekształciły się w mursz ziarnisty. W warstwie 20–50 cm nastąpił blisko dwukrotny wzrost popielności, a w części torfowisk gleby organiczne przekształciły się w gleby mineralne i organiczno-mineralne. Największe zmiany wystąpiły w regionie rolniczym. We wszystkich torfowiskach na terenie Parku trzykrotnie zmalał obszar użytków zielonych i pięciokrotnie wzrosła powierzchnia lasów. Obecnie 10% ich powierzchni zajmują grunty orne, których uprzednio nie było wcale.

    Opis:
    This paper presents results of abundance field research, distribution and habitat and phytocoenotic preferences of Trisetum sibiricum on the Gutowo Meadows (Urszulewo Plain, NE Poland), in a locality outside the continuous range of distribution. The species grown in wet, not used meadows, in places overflooded by beavers, partially afforested. The research was carried out in 2013 and the results were compared with analogical data from 2000–2002. Currently a higher abundance of species (circa 1600 tufts), a larger area of the locality (circa 2.5 ha), larger phytosociological spectrum and a larger share of hygrophilous species in species composition of the examined phytocoenoses was revealed. In 2013 a share of Trisetum sibiricum was noted in 12 plant communities from seven classes (Phragmitetea australis, Scheuchzerio-Caricetea nigrae, Bidentetea tripartiti, Molinio-Arrhenatheretea, Artemisietea vulgaris, Alnetea glutinosae and Querco-Fagetea), and in 2000–2002 – only in seven plant communities from three classes (Scheuchzerio-Caricetea nigrae, Molinio-Arrhenatheretea and Artemisietea vulgaris). Formerly the species was listed mainly in phytocoenoses of Angelico-Cirsietum oleracei and currently most often in phytocoenoses of Junco-Molinietum.
