Found in the moist lowland and monane rainforest. Brown Lemurs are tree dwelling and spend most of their time in the upper layers of the forest. Restricted to north-eastern Madgascar. Destruction of the rainforest in north-eastern Madagscar by slash-and-burn agriculture is the primary threat to the White-fronted Lemur. Hunting and trapping for food or the pet trade also pose a significant threat to this Lemur in many parts of its range.
