This Database is currently being updated, expanded and migrated to a new platform. The sifaka lemur (Propithecus verreauxi) has been studied at the Bezà Mahafaly Special Reserve in southwest Madagascar since 1984. The Yale Peabody Museum hosts the Sifaka Database, under a collaborative agreement with the School of Agronomy, University of Antananarivo. The Database includes monitoring information on over 900 individuals. The purpose of the Database is to support research, serve as a resource for teaching, and contribute to the conservation of biodiversity in and around the Bezà Mahafaly Special Reserve. The Reserve is the focus of a longstanding, community-based conservation partnership. Additional information about partnership activities can be found on its website here.
