Berenty Reserve, Private natural reserve in Toliara Province, Madagascar.

Berenty Reserve is a protected area in southern Toliara Province with gallery forests along the Mandrare River and expansive spiny forest habitats filled with endemic plants and animals. A network of walking trails connects different forest zones and provides access to varied woodland ecosystems.

Berenty Reserve was created in 1936 as part of a 1,000-hectare block of residual spiny forest, together with Bealoka and Rapily, within Henry de Heaulme's former sisal plantation. The primatologist Alison Jolly began her lemur research there and published several books on the reserve.

The site serves researchers as a field station where they document and observe the behaviors of ring-tailed lemurs and other species in their natural setting. Visitors can witness this work firsthand and learn about the ecological characteristics of this region.

The reserve lies about a two-hour drive from Tôlagnaro (Fort Dauphin) on the southeast coast. Accommodation is available in the forest, and a set of forest trails leads through the spiny forest. It attracts more visitors than any other nature reserve in Madagascar.

The reserve lies within a 1,000-hectare block of residual spiny forest that also takes in Bealoka and Rapily, on the land of Henry de Heaulme's former sisal plantation. The correct genus name of the tall spiny trees is Alluaudia. Alison Jolly published several books about Berenty.
