Northern and a south-eastern population. The latter is situated foremost in the Danube countries and holds about 650 White-tailed Sea Eagle pairs, of which almost 200 are ecologically dependent on the river Danube and its remaining alluvial floodplain. The goal of this Action Plan is to secure a Viable population of the Whitetailed Sea Eagle along the Danube. Through national action and international co-operation, White-tailed Sea Eagle habitats are to be secured and major man-made threats are to be eliminated. The Danube is to be saved as the backbone for White-tailed Sea Eagles in South-Eastern Europe, acting as a source breeding subpopulation as well as an important wintering place for eagles coming from the north-east of the continent. The saving of this flagship and umbrella species along the Danube should be a best practice example for transnational conservation of species and habitats. Based on the recovery of this species, transnational co-operation of stakeholders should be built up.
