Madagascar dry deciduous forests

The Madagascar dry deciduous forests is a tropical and subtropical dry broadleaf forests ecoregion located in the Afrotropic biogeographic realm, covering sub-Saharan Africa and the southern Arabian Peninsula, spanning approximately 151,560 km². Classified under the WWF ecoregion code AT0202, this region represents a distinct ecological community shaped by its unique combination of climate, geography, and evolutionary history.

Climate and Vegetation

This ecoregion experiences warm with a pronounced dry season lasting several months. The dominant vegetation consists of deciduous or semi-deciduous broadleaf trees that shed leaves during the dry season. These conditions create the foundation for the ecological communities found within the Madagascar dry deciduous forests.

Ecological Significance

These forests support lower species density than their moist counterparts but harbour many endemic species adapted to seasonal drought. Fire plays an important ecological role in maintaining forest structure. The Madagascar dry deciduous forests contributes to the broader biodiversity patterns of the Afrotropic realm.

Geographic Distribution

The Madagascar dry deciduous forests extends entirely within Madagascar. This geographic range places it within the Afrotropic realm, one of the eight major biogeographic divisions of the world.

Notable Species

The Madagascar dry deciduous forests supports a range of wildlife, including Abalone (Haliotis unilateralis), African dogstooth grass (Cynodon transvaalensis), African jointgrass (Hemarthria altissima), African senna (Senna didymobotrya), ambatch (Aeschynomene elaphroxylon), American Black Nightshade (Solanum americanum), American carpet grass (Axonopus compressus), Andaman Redwood (Pterocarpus dalbergioides), and 42 more species. Among these, 1 species is classified as threatened on the IUCN Red List, underscoring the conservation importance of this ecoregion.

Conservation

Like many tropical and subtropical dry broadleaf forests ecosystems, the Madagascar dry deciduous forests faces threats from conversion to agriculture, fire regime changes, and cattle ranching. Conservation efforts in this ecoregion focus on habitat preservation, sustainable land management, and protecting corridors that connect fragmented habitat patches.
