The aim of the paper is the estimation of hydrological conditions occurring on the area of Przemkowsko- Przecławskie Wetlands in the proposed water management scenarios, which are implemented to restore natural values of the wetland environment .In each of the scenarios, the operation parameters of hydraulic structures were changed, causing the potential increase of ground water alimentation to the wetland area. Common and recognized ground water flow model MODFLOW was used to calculate ground water levels for each scenario and to study the long –term effect of restoration measures on Przemkowsko – Przecławskie Wetlands. Following hydrological characteristics were analysed: mean of the mean ground water levels, inundation frequency, mean ground water amplitude and mean low ground water levels. These characteristics were modeled for the long-term period 1964-1985 for unsteady flow conditions and were compared with the values adopted from intact, reference wetlands. It was proved, that slowing down the outflow of ground water (scenario 1) didn’t provide hydrological conditions desired for the maintenance of swampy habitats. The combination of outflow slow down and restriction of ground water abstraction by existing pumping stations (scenario 2) didn’t guarantee the maintenance of desired values of hydrological characteristics for a swampy habitat as well. The realization of the proposed scenarios enables to keep proper conditions for wet and moist habitats. The management policy for Przemkowsko - Przeclawskie Wetlands should then be directed at the development of those habitats, providing broad realization of environmental protection goals.

The invasiveness of Robinia pseudoacacia, one of the most invasive alien tree species in the agricultural landscapes of Central Europe, was studied in relation to its colonization of various soil and habitat types. The study area was a traditional agricultural landscape in Goričko Landscape Park (Slovenia), a hilly region, where half the territory is covered by forests and where R. pseudoacacia is also common. Habitat mapping in the field with a resolution of two meters was applied and further elaborated in GIS. It revealed 1307 patches colonized by R. pseudoacacia and belonging to 11 habitat types, covering 0.6% of the total study area. The most widespread were pure R. pseudoacacia stands, representing 69% of the total patch area. R. pseudoacacia is also abundantly present in small woodlots (19%) and in lowland and collinar riverine willow scrub (6%). The patches vary little in fractal dimension; the elongation index is highest in lowland and collinar riverine willow scrub, stream ash-alder woods and mixed stands. The most frequently invaded soil is pseudogley, with more than 38% of the total surface, followed by 21% for fluvisol and 17% for eutric cambisol. We confirmed that distance from nearest woodland is important, since almost 32% of the invaded patches are found at a distance of 1–100 meters from closed woodland.

Habitat edges are regarded as important components of heterogeneous landscapes. Diverse theories exist about the diversity and functional role of edges, and no generalisation have been possible so far, thus case studies are important for better understanding the landscape scale processes. Forest management highly modified the structure and tree species composition of the European forests. The sylvicultural intensification resulted in the rise of the proportion of non-native, intensively managed forest stands. In the present study we explore the response of spider and ant assemblages to forest stand type and the edge effect between native poplar and non-native conifer plantations in Hungary. We applied pitfall traps to sample the ground-dwelling spiders and ants. Four plots consisting of the two forest types and the transition zones between them were selected. Five transects for each replicated plot were sampled. We identified the significant indicator species of the different habitat types. We found significant differences in the species richness (i.e. number of species) of ants and spiders of the different habitat types. We detected intermediate spider species richness at the edge indicating that edges separate a higher quality habitat from one that has lower resource quality; however, the species richness of ants was the highest at the edge and did not differ between the two forest types. The positive impacts of edge was found due to presence of generalist and grassland species at the edge and presumably edges separate patches that provide complementary resources also increasing the number of ant species.Our results indicate that forest type affects the species compositions of ground-dwelling spiders and ants. Our study also shows that habitat type had a major effect on the species richness and composition of spider and ant assemblages, suggesting that local forestry management plays a crucial role in preserving the native invertebrate fauna of forests.

Determining ecological corridors is crucial for conservation efforts in fragmented habitats. Commonly employed least cost path (LCP) analysis relies on the underlying cost matrix. By using Ecological Niche Factor Analysis, we minimized the problems connected with subjective cost assessment or the use of presence/absence data. We used data on the wolf presence/absence in Poland to identify LCPs connecting patches of suitable wolf habitat, factors that influence patch occupancy, and compare LCPs between different genetic subpopulations. We found that a lower proportion of cities and roads surrounds the most densely populated patches. Least cost paths between areas where little dispersal takes place (i.e., leading to unpopulated patches or between different genetic subpopulations) ran through a higher proportion of roads and human settlements. They also crossed larger maximal distances over deforested areas. We propose that, apart from supplying the basis for direct conservation efforts, LCPs can be used to determine what factors might facilitate or hinder dispersal by comparing different subsets of LCPs. The methods employed can be widely applicable to gain more in-depth information on potential dispersal barriers for large carnivores.

Presence of plant species, associated with ancient forests (continuous existence >200 years) can be used for assessing woodland biodiversity. The aim of this study is to specify which plant species, included in the ancient forests plant species list, can indicate old woodlands in parks and what plant features are characteristic for certain habitat types. Richest in ancient forest plant species are those fragments of woodlands, which have existed continuously for at least 120 years, and their fragments suffered least from human pressure during that time, whereas recent woodlands are characterized by a small share of ancient forest indicator species and domination of nitrophilous species. Investigated plants usually propagate vegetatively, their seeds are of a small size and they have regularly, densely set leaves. Plants associated with ancient woodlands are good indicators of woodland continuity in parks so they can be used for age assessment in these areas. Accumulation of such plants can be a useful criterion in parks evaluation. Proposed idea of sustainable management of a park space, including selection of areas of a great ecological value, can be a chance to preserve woodland biodiversity.

To study variation in the diet of the raccoon dogNyctereutes procyonoides Gray, 1834 in northern Belarus, 3299 scats were sampled from 18 localities differing in habitat quality. In one of the 18 localities, the dietary study was conducted for nine years. The data obtained was analysed according to seasonality, between-year difference, family specificity and habitat influence. In northern Belarus, the raccoon dog was found to be a generalist predator with omnivorous and opportunistic feeding habits. Their diet was highly variable, but a common trait was specialization on carrion in winter and on berries in late summer. Beside carrion and berries, the other seasonally important food items were frogs, insects, plant matter, mammals, and birds. The diet varied between seasons and habitats. In the warm season, habitat factors, such as type of soil (clay or sand), proportion of lakes and open grassy marshes, seemingly determine the food supply for raccoon dogs, and thereby influence the diet of individuals. The obtained results on dietary variation of raccoon dogs can be used in detailed analysis of the impact of this introduced species on native fauna and its role in functioning of vertebrate communities.

Late spring/summer depth and velocity conditions of 16 ‘functional habitats’ were investigated in lowland rivers. The habitats significantly associated with shallower, faster areas were 'submerged, fine-leaved macrophytes' (20-40 cm deep, >0.45 ms-1) and 'macroalgae' (10-30 cm, >0.60 ms-1). 'Cobbles' were associated with slightly slower, shallower conditions (0-20 cm, 0.45 ms-1), 'gravels' with slower conditions again (around 0.15 ms-1, depths from 0-30 cm). The slowest velocity class (0-0.05 ms-1) was associated with 'silt' (depths 20-70 cm), ‘marginal plants' (0-20 cm deep), 'emergent macrophytes' (10-80 cm deep), 'submerged, broad-leaved macrophytes' (40-110 cm deep), 'floating leaved macrophytes' (40-150 cm deep) and a second mode of ‘macroalgae’ (145-180 cm deep). The factors thought to be behind these findings are discussed.
