The western woolly lemur is listed as endangered due to its very limited habitat. It is confined to a small area of dry forest in western Madagascar — and even within this small area, suitable habitat is very fragmented. They mostly live in Ankarafantsika National Park, where I saw this young western woolly on a night hike back in 2007.
