Opis:: The objective of this study was to estimate the edge effect on the species richness in agriculturally maintained forest-grassland boundaries of coniferous forest and to determine how species respond to a forest edge. We hypothesised that species number, cover of herbs and mosses is higher in the edge, and species penetrates from nearby grasslands into forest interior. The study was conducted in the Southwestern Lithuania. The edge effect on overall herbaceous species composition of coniferous forests was evaluated by Canonical Correspondence Analysis. The species richness of herbs and mosses in the coniferous forest was highest in the forest edge and declined towards interior. The highest decrease in the number of species occurred within 0 to 5 m to the edge. The highest cover of herbs and mosses was in the forest edge and decreased towards the forest interior. CCA biplot showed a good correlation of overall species composition and the distance to the forest edge. Distribution of species along edge to interior gradient depended on the species response to different ecological factors. Ellenberg value of light was higher in the edge. Ellenberg value of nitrogen was higher in the forest interior.

Opis:: Forest edges generally represent a very important element of ecological stability. The goal of this paper is to classify the types of anthropogenic forest edges in the area of Starohorské Mountains and to analyze anthropogenic impacts on the selected attributes of forest edges. We evaluated the attributes of a biocomplex, type of forest edge, its structure, consistence, species composition and other factors. The differences in environment variables and anthropic impact were influenced by singularities in the composition and species variability of vegetation. In the monitored areas we defined seven types and four subtypes of forest edges according to its vertical and horizontal structure. With the help of detrended correspondence analysis (DCA) we also interpreted organization relevés and species by gradients of environment variables, and with the help of canonical correspondence analysis (CCA) we tested their statistical significance. From the results of our research, there is a clear tendency for high diversity of living species in the forest edge. Environmental variables interpreting the highest volume of species variability are the altitude and transect position.

forest edge
Opis:: The study presents the Geographic Information System created to analyse spatial distribution of wind-induced damages in forest stands of the Tuchola Forest, northern Poland, and in the vicinity of Toruń. It was used in several forest complexes mainly on the territory of the following Forest Districts in the Tuchola Forest: Woziwoda, Przymuszewo and Czersk, as well as in the Bory Tucholskie National Park. The following Forest Districts were analyzed in the vicinity of Toruń: Gniewkowo, Golub-Dobrzyń, Dobrzejewice and Toruń. The damages in Tuchola Forest were caused mainly by hurricanes in 26th of December 1999 and 22nd of June 2000. The dates of hurricanes caused the largest damages in the vicinity of Toruń were 17th of July 2001 and 28th of October 2002.
