Madagascar succulent woodlands
The Madagascar succulent woodlands are a xeric shrublands ecoregion in southwestern and central western Madagascar. They are threatened by various human activities. Geography. The succulent woodlands are found in the southwest and centre-west of Madagascar, in the rain shadow region that receives less moisture than the east and the Central Highlands. The climate is tropical and dry, with rainfall ranging from 575 to 1,330 mm per year, and a marked dry season from May to October. To the north, the succulent woodlands make a transition into the Madagascar dry deciduous forests, while to the south, they  border the even drier Madagascar spiny thickets and to the east, the Madagascar subhumid forests. Flora. The vegetation is similar to the dry deciduous forests to the north, but includes more dry-adapted, xerophytic species. Forests, reaching in height, contain trees and shrubs of the families Burseraceae, Euphorbiaceae, Fabaceae, and Sapindaceae. Notable endemics include two species of baobab, "Adansonia za" and "A. grandidieri" (near threatened and endangered, respectively), and succulents in the genus "Pachypodium". Fauna. Between 60 and 90 bird species and eight lemur species are found in the ecoregion and a number of mammals, frogs, and reptiles are endemic  to the area. A notable lemur species is the endangered Madame Berthe's mouse lemur, the world's smallest primate. Threats and conservation. The Madagascar succulent woodlands are threatened by burning, logging (which impacts species such as the endemic tree "Hazomalania voyroni"), cattle and goat farming, and hunting of several mammals. Protected areas include Zombitse-Vohibasia National Park, Andranomena Reserve, Kirindy Mitea National Park, and Kirindy Forest.
