The Island of Madagascar, off the southeastern coast of Africa, is home to dozens of species of lemurs—and almost all of them are disappearing very quickly due to habitat loss and illegal hunting. But the most critically endangered of all of Madagascar’s lemurs is the greater bamboo lemur (Prolemur simus), also known as the broad-nosed gentle lemur. Fewer than 100 greater bamboo lemurs remain in the island’s southeastern and south-central forests, and they continue to be threatened by illegal hunting as well as habitat loss due to logging and the burning of forests for agricultural purposes.
