The influence of intersections and dead-ends of line-corridor networks on the breeding bird distribution

Folia Zoologica

Abstract

The breeding bird communities in four networks of line corridors were studied during the period 1993-1996 with the aim to characterise the influence of intersections and dead-ends of corridors on the breeding bird distribution. The results of this study show that species richness and number of territories in line-corridors depend on the vegetation volume, width and distance of the section from the nearest intersection or dead-end. Moreover, the abundance of corridor-dependent species is influenced not only by the distance of the section from the nearest intersection or dead-end, but also by the section type. Sections adjacent to intersections support more territories of corridor-dependent species. In our study we recorded increasing number of territories of nightingale, blackcap, whitethroat, lesser whitethroat along with the decreasing distance of sections from dead-ends or intersections. Territories of great tit and icterine warbler were more common in sections adjacent to intersections. Only one species (tree sparrow) was associated with sections adjacent to dead-ends.
