Hispaniolan dry forests

The Hispaniolan dry forests is a tropical and subtropical dry broadleaf forests ecoregion located in the Neotropic biogeographic realm, covering Central and South America, the Caribbean, and southern portions of Mexico, spanning approximately 15,446 km². Classified under the WWF ecoregion code NT0215, 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 Hispaniolan dry 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 Hispaniolan dry forests contributes to the broader biodiversity patterns of the Neotropic realm.

Geographic Distribution

The Hispaniolan dry forests extends across Dominican Republic and Haiti. This geographic range places it within the Neotropic realm, one of the eight major biogeographic divisions of the world.

Notable Species

The Hispaniolan dry forests supports a range of wildlife, including Aaron'S Rod (Verbascum thapsus), African Rice (Oryza glaberrima), Apple Snail (Pomacea glauca), Argyle apple (Eucalyptus cinerea), arizona-cypress (Cupressus arizonica), Aroma (Dichrostachys cinerea), Awnless Barnyard Grass (Echinochloa colonum), Beauty Of The Night (Mirabilis jalapa), and 42 more species.

Conservation

Like many tropical and subtropical dry broadleaf forests ecosystems, the Hispaniolan dry 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.
