The breeding grounds of the endangered Eastern Imperial Eagle extend from south eastern Central Europe to Lake Baikal in Siberia. The European population is estimated at 1,100 to 1,600 breeding pairs. 

Populations in Eastern Europe are now highly fragmented. The aim of the project supported by VGP Foundation and led by NABU International, is to improve the conservation measures for the Eastern Imperial Eagle by transferring knowledge between existing conservation projects and closing knowledge gaps. The focus lies on the investigation of relevant factors for a recolonization of former habitats and the investigation of potential threat factors in the wintering areas.
