The collared brown lemur, scientifically known as Eulemur collaris, is a species of lemur native to Madagascar. Here’s a description of its distribution:

1. Madagascar: Collared brown lemurs are found exclusively on the island of Madagascar, which is their native and only habitat. Within Madagascar, they are distributed across various regions of the island, particularly in the eastern rainforests and deciduous forests.

Collared brown lemurs inhabit a range of forest types, including lowland rainforests, montane rainforests, and dry deciduous forests. They are arboreal, meaning they spend most of their time in the trees, where they forage for leaves, fruits, flowers, and other plant materials.

Like many lemur species, collared brown lemurs face threats from habitat loss due to deforestation, logging, and agriculture. Additionally, they are sometimes hunted for bushmeat. Conservation efforts are underway to protect their remaining habitats and ensure the survival of this species.
