Nowadays, a great deal of discussion is made worldwide about the conservation of the biodiversity. In most cases, both the changes in the ecosystems and decline in biodiversity are due to human activities. In the Mediterranean region, the present habitat diversity has been the result of the temporal presence of humans through traditional activities that leaded in a great heterogeneity in the natural environment. In Greece, the intensification of human activities during the last decades resulted in a great degradation of the ecosystems and shrinking of the available habitats for many species of plants and animals. One of the few remaining natural areas is the National Park of Dadia-Lefkimi-Soufli where the high ecological quality of the environment supports many species of plants and animals, especially many raptor species in high population levels. The ecosystems are complicated units including many species in different spatial levels with varying habitat demands. Knowledge on the appropriate management of the National Park’s forests is necessary to safeguard both wood production and raptors’ biodiversity conservation in this area. The aim of this study was the study of the effect of environmental factors on the nesting habitat selection of diurnal birds of prey coexisting in the area of the National park. In this area coexist 18-20 species of breeding birds of prey. The species studied were Black Vulture (Aegypius monachus), Booted Eagle (Hieraaetus pennatus), Lesser-spotted Eagle (Aquila pomarina), Goshawk (Accipiter gentilis) and Buzzard (Buteo buteo). All nest on trees and in high population levels. Their body sizes result in special needs for particular habitat types. We also studied the Black Stork (Ciconia nigra), which is not a raptor species but coexists in the same habitats with the above mentioned birds of prey. The habitats of the area are characterized by a great heterogeneity. The environmental factors and their spatial distribution were analysed using Geographical Information Systems (GIS) that ...
