Documentation of commercial and subsistence hunting of Critically Endangered black-and-white ruffed lemurs (Varecia variegata) in northeastern Madagascar.

Hunting of wild animals for meat and habitat loss are the main drivers of wildlife population decline around the world, and in tropical regions in particular. While Madagascar is a hotspot for biodiversity, hunting is widespread, mostly in form of subsistence hunting, while hunting for the pet trade is less often reported. We studied hunting of the Critically Endangered black-and-white ruffed lemur (Varecia variegata) in northeastern Madagascar. Using lemur surveys (102.7 km survey effort) and 54 semi-structured and seven key informant interviews, we assessed the local knowledge, hunting pressure, and the perceived and actual abundances of V. variegata in two hunting and two non-hunting villages. V. variegata was well known (> 83%) by the respondents but abundance estimates differed significantly between hunting and non-hunting villages, with 26% and 77% of respondents, respectively, estimating a high abundance of ruffed lemurs in the adjacent forests of the villages. Actual observations of V. variegata also differed strongly, in accordance to perceived abundances. Hunting was either done by trapping animals or by pursuit hunts. In both hunting villages, adult lemurs were used for direct meat consumption and juveniles for rearing for the later trade. Hand-raised V. variegata were reported to be sold for 38–71 USD on regional markets or 'delivered' directly to buyers. While wildlife hunting has been widely reported from all over Madagascar, commercial hunting, hand-rearing and trading adds a new dimension of threat towards these Critically Endangered lemurs. As such, the extent of the trade is a priority for future studies. [ABSTRACT FROM AUTHOR]
