The Ramsar Site includes the four surrounding watercourses (the Sahabe, Sasomanga, Sahamaloto and Anony) and their catchment areas. The wetlands are linked to the Indian Ocean by the Maningory River. The Site is an excellent representative example of the natural wetlands of the eastern Madagascar biogeographical region and includes nine of the twenty inland wetland types identified in the Ramsar system of classification, as well as seven of the ten human-made wetland types. The Site is the only natural habitat of the critically endangered Lac Alaotra bamboo lemur (Hapalemur alaotrensis, known locally as bandro) which is the only primate species in the world that lives exclusively in reed beds. The wetlands surrounding the lake have local cultural significance.
