The breeding bird communities of the Kamienica watershed in Gorce National Park (The Carpatians, SouthernPoland)
Abstract:
The breeding com m unities of birds in the forests of the Kamienica watershed consist of 22-43 species with a total density of 31-75 pairs per 10 ha. Most abundant in this respect are the beechwoods, least rich in species are coniferous forests with the spruce on northern slopes. A very high species diversity (H´= 4.6 and 4.2) is observed in the avifaunas of the semi-natural alder-spruce fen and of the natural beechwood. The avifauna of the fen is ecotonal and transitional between a mountain and a lowland fauna. The evaluation of bird community structure has been based on the detailed mapping method. The point-count methods tested against it lowers the number of species increasing, at the same time, the bird density by at least 29%.
