In the analysis of Black Stork nests spatial distribution an overlay approach in GIS was
used. The analysis was performed on three levels: 1 – level of general analysis of forests
structure in the entire study area (forestries level), 2 – level of separate breeding territories
(500m buffer zones around individual nests, see fig. 2) and 3 – level of individual nests
locations (spatial joining of attributes from forest plots to point layer of nest locations).

the Black Stork nests spatial distribution in relation to forest habitats.

In some previous studies, other researchers usually used bigger buffer zones around
nests (e.g. 2,8 km; [6, 10, 11]) to analyze forest structure there. We decided to use much
