The zoological gardens united in AEECL are coordinating the European Endangered Species Programmes (EEP) for the:
Blue-eyed black lemur (Eulemur macaco flavifrons)
Crowned lemur (Eulemur coronatus)
Red-bellied lemur (Eulemur rubriventer)
in the framework of the European Association of Zoos and Aquaria (EAZA). These programmes aim at establishing self-sustaining captive populations of the species which can serve both as model populations to learn more about the species’ biology as well as reserves for possible future reintroduction projects.
