The Madagascar bioregion, part of the Madagascar & Eastern Afrotropics subrealm located in the Afrotropics realm, is separated from the African continent by the Mozambique Channel dominated by humid tropical forests in the east, drylands in the south, and dry forests in the north. 

The bioregion contains eight ecoregions—Madagascar Humid Forests (17), Madagascar Subhumid Forests (18), Madagascar Dry Deciduous Forests (32), Madagascar Ericoid Thickets (83), Ile Europa and Bassas Da India Xeric Scrub (96), Madagascar Spiny Thickets (99), Madagascar Succulent Woodlands (100), Madagascar Mangroves (114)—with a total land area of more than 59 million hectares, making it the fourth largest island in the world. 

Due to the island’s physical isolation, it shelters extraordinary biodiversity with nearly 15,000 plant species, four-fifths of which are found nowhere else on Earth. It also has 300 bird and 260 reptile species, the majority of which are endemic. The lemur is the keystone mammal of the island, with over 100 species recorded.

The Madagascar bioregion is part of the Madagascar & Eastern Afrotropics subrealm and is made up of eight ecoregions: Madagascar Dry Deciduous Forests [1], Madagascar Subhumid Forests [2],  Madagascar Humid Forests [3], Madagascar Succulent Woodlands [4], Madagascar Spiny Thickets [5], Madagascar Mangroves [6], Madagascar Ericoid Thickets [7], Ile Europa and Bassas Da India Xeric Scrub [8].
