The passerines of agroforestry systems in Greece

This study is based on the review of the existing literature and is an attempt to define the various passerine species (Passeriformes) encountered in Greek agroforestry systems, classified in the various habitats and the requirements to cover their basic biological needs for survival and reproduction. Furthermore there is reference to the problems of the protection and management of agroforestry systems due to maintain biodiversity. From the 138 species occur systematically in Greece, 102 use agroforestry systems at different times of the year, spreading from sea level to the sub-alpine zone and are distributed throughout Greece.
