Vogrin, M. (Hajdina (Slovenia))
In 1998 survey on breeding birds was carried out on a sample plot of 13.3 ha in the beech-spruce forest on Dobrovlje Karst Plateau in the Kamnik-Savinja Alps. 25 species were breeding within a mapping plot, reaching a density of 62.4 pairs per 10 ha. Looking at the overall abundance, Regulus regulus and Parus ater possess together 31 percent of all territories. Number of migrants presented with one species only was very low. The most numerous group according to its biomass was a group of species that nests in the crown with 75.5 percent. The breeding bird assemblage near Kraple farm has a composition of species and its density similar to assessed associations in other parts of Dobrovlje Plateau. According to Sorensen and Rekonen Index the similarity of bird assemblages depends also on geographical position and latitude.
