Habitat and Distribution of the Ruffed Lemur,Varecia, North of the Bay of Antongil in Northeastern Madagascar

Abstract

Abstract: Here we present information on the conservation status of ruffed lemurs (Varecia) north of the Bay of Antongil in northeastern Madagascar. Two contiguous protected areas were recently established that traverse this region via blocks of forest connected by narrow forest corridors: the Masoala National Park, which expands further to the east, and the Makira Protected Area, which expands further to the west and northwest. The two extant ruffed lemurs, Varecia variegata and V. rubra, overlapped in this region historically and, on rare occasions, hybridized. As such, land north of the Bay of Antongil is a critical part of the ruffed lemur's northern geographic range. Habitat surveys and interviews with local informants were carried out in this region to determine the extent of suitable habitat for Varecia populations, to assess the extent of human exploitation of this genus, and to obtain data on the western and northern range limits of V. rubra. Interviews indicated that there are populations of V. ...
