Ornithological survey of lowland forest fragments, with special reference to the biotope characteristics

The Author studied the composition of the bird communities in 25 forest fragments in the vicinities of Tiszavasvári. Nesting of 41 species has been documented, the pair numbers showing significant variability among sites. Correlation analysis was applied to identify the parameters influencing the composition of the avifauna - area of the forest fragment, its circumference, shape, tree species composition, tree trunk diameters, distance to the nearest forest fragment, and length of tree-rows within a radius of 800 m have been taken into consideration. Only the area and tree-rows within 800 m showed significant correlation with the species composition. The study has unequivocally demonstrated that in deforested agricultural regions such tree-stands - even if but 1-2 hectare in size - are of considerable importance for the preservation of forest bird species, and their natureprotection value should not be neglected.

Key words: forest fragment, bird community, Tiszavasvári, Hungary
