Overview
sub-arid climate. Temperatures are highest on the west coast, with annual means of up to 30 °C (86 °F), while the high massifs have a cool climate, with a 5 °C (41 °F) annual mean locally. Geology features mainly igneous and metamorphic basement rocks, with some lava and quartzite in the central and eastern plateaus, while the western part has belts of sandstone, limestone (including the tsingy formations), and unconsolidated sand.[1]

Freshwater ecoregions
catchment
areas with a distinctive assemblage of species. In Madagascar, five ecoregions are distinguished:
- Madagascar Eastern Lowlands includes the lower humid-climate coastal plain of eastern Madagascar.[3]
- Madagascar Eastern Highlands includes the middle and upper catchments of Madagascar's eastern coastal rivers.[4]
- Northwestern Madagascar encompasses the westward-flowing South Mahavavy (Mahavavy du Sud).[5]
- Western Madagascar encompasses the drier western river basins, including the Manambolo, Tsiribihina, Mangoky, and Onilahy rivers.[6]
- Southern Madagascar encompasses the southern drainages of Madagascar, including the Mandrare, Manambovo, Menarandra, and Linta rivers, along with Lake Tsimanampetsotsa.[7]
Marine ecoregions
The seas around Madagascar are part of the Western Indian Ocean province in the Western Indo-Pacific realm. They are divided into two
marine ecoregions:[8]
- Southeast Madagascar
- Western and Northern Madagascar
