This site is located on the northern bank of the Onilahy river, about 20 km south of Toliara. It is bordered in the west by rocky banks and humid sands and has a rugged micro-relief. A tributary of the Onilahy rises within the forest. The vegetation is composed of xerophilous bushland, dominated by Euphorbiaceae, with an open canopy (up to 4–5 m high).
See Box and Tables 2 and 3 for key species. Calicalicus rufocarpalis, a recently described species, is known only from this site and from the Mahafaly Plateau Forest complex (IBA MG070).
Pressure/threats to key biodiversity
Most of the bushland is intact, except along the road-edge, where it was significantly exploited in the past, especially for charcoal production. The risk of habitat destruction is currently low since the local population is composed of fishermen.
