I surveyed the Anaovandrano River Watershed to assess whether large tracts of primary lowland rain forest still occur there and to what extent red ruffed lemurs (Varecia variegata rubra) populate the interior of the Masoala Peninsula. These data permit an informed estimate of the remaining population size for this subspecies. I located large tracts of primary lowland rain forest in the interior, but fragmentation has begun. Red ruffed lemurs appear to be less dense in the interior than they are in remaining lowland coastal rain forest. I estimate the remaining population size to be between 29,682 and 51,115 individuals. Breeding population size is substantially smaller, probably <14,841 individuals.
