Site description
This site lies c.10 km from Sakaraha and 130 km from Toliara, and consists of the Zombitse, Vohibasia and Isoky-Vohimena Forests, which cover a gently undulating terrain of dome-shaped sandstone hills. The Isalo massif lies to the east, and a calcareous plateau (820 m high) to the west—both are oriented north–south. The soil is sandy. The Fiherenana and Teheza rivers, tributaries of the Onilahy, rise within the Zombitse and Vohibasia Forests. The vegetation consists of dense deciduous forest and xerophilous bushland, dominated by Securinega, Malleastrum, Carissa and Teclea, with some emergents, such as Commiphora and Brachylaena. The xerophilous bushland is characterized by species of Euphorbia, Adansonia and Dialium.
