One of the world’s biggest populations of greater bamboo lemurs (Prolemur simus)—sometimes known as the panda lemur—has doubled in just three years, giving conservationists new hope that the species can be kept from extinction. With the recent arrival of twenty babies, a community conservation project run by the Aspinall Foundation has boosted the local population to over 100 individuals in Andriantantely, one of Madagascar’s only surviving lowland rainforests. Greater bamboo lemurs are currently categorized as Critically Endangered, though they were once believed extinct until hidden populations were uncovered in the 1980s.
