On the basis of forest taxation data the presence of European ash in the Bardzkie Mountains area (central part of the Sudety Mountains) was analysed. This included the reckoning of the number of sites and the area covered by ash in various forest habitat types, age classes, altitude zones and on variously slanted and exposed mountain sides. The decline in the number of ashes in younger age classes and complete absence of trees older than 140 years have been noted. In the Bardzkie Mountains ash is the main species forming the forest on mountain riparian forest stands (a 43% participation in the area of forest of this type). Considering the number of specimens most ashes are scattered in mountain broadleaved forest. To the altitude of 650 m ash’ participation in the forest stand composition is stable (30% of analysed locations), but it occupies only 2.6% of total forest area.
The aim of the study was to discover habitat preferences of the forest dung beetle Anoplotrupes stercorosus (Scriba, 1791). Beetle specimens were collected using modified Barber traps in the Białowieża Forest, in 1999. In total, 14980 specimens of the forest dung beetle were collected. According to the obtained results, the optimal habitat types of the beetle in question included fresh broadleaved forest, fresh mixed broadleaved forest, fresh mixed coniferous forest, moist broadleaved forest and fresh coniferous forest. It was discovered that the beetle in question was more abundant in fresh forest habitats than in moist and boggy forest habitats or in alder swamp forests.
