The Mikea Forest (or ForĂȘt des Mikea) is a forested region of southwestern

, between Manombo and Morombe. More specifically, it stretches from Route Nationale 9 to the west coast and from Mangoky south to the Manombo River. It lies at the transition between dry deciduous forest, which is more common further north in Madagascar, and spiny forest, which is dominant in southwestern Madagascar. Its underlying geology is unconsolidated sand, and the region contains several freshwater lakes. The ForĂȘt des Mikea is one of the largest remaining continuous forest blocks in western and southern Madagascar, but it is not protected and it is threatened by human development. This transitional terrain is one of the least protected of Madagascar's habitats. This soil composition has resulted in a collection of plant and animal species, even distinct from adjacent vegetation on limestone. Small terrestrial mammals found here include the rodents '' Macrotarsomys bastardi'', '' Macrotarsomys petteri'', and the introduced
black rat The black rat (''Rattus rattus''), also known as the roof rat, ship rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus ''Rattus'', in the subfamily Murinae. It likely originated in the Indian subcontinent, but is n ...

''Macrotarsomys petteri'' and ''Microgale jenkinsae'' are unique to the forest and were only discovered in the 2000s. The popular

of bird in Madagascar, only two ('' Monias benschi'' and '' Uratelornis chimaera'') were not found in protected areas, but both were fairly common within the unprotected forests of Mikea. ''Monias benschi'' had an estimated population of 115,000, while the ''Uratelornis chimaera'' population was estimated at fewer than 15,000. A survey published in 2005 reported that 59 species of reptile were identified near the eastern shore of Lake Ranobe in the southern Mikea Forest, five of which were vulnerable. Some of these species include '' Matoatoa brevipes'', '' Oplurus fierinensis'', '' Furcifer antimena'', '' Furcifer belalandaensis'', '' Phelsuma standingi'', and '' Pyxis arachnoides''. The flora includes the baobabs '' Adansonia za'' and '' A. rubrostipa''. Between the 1960s and the 2000s,
