The Hispaniolan dry forests are a tropical dry broadleaf forest ecoregion on the island of Hispaniola (split between the Dominican Republic and Haiti).
[1] The dry forests are found mostly on the southern and western portions of the island of Hispaniola, covering portions of both the Dominican Republic and Haiti.
[1] Plant communities include high dry forest and cactus scrub dominated by species of Prosopis, Pilosocereus, Hippomane, Cylindropuntia, Agave, and Bursera, as well as Melocactus lemairei.
Species found include Ricord's iguanas (Cyclura ricordii), rhinoceros iguanas (C. cornuta), Hispaniola racers (Haitiophis anomalus), and Barreras fanged snakes (Ialtris agyrtes).
A 2017 study found that extinct giant tortoises (Chelonoidis marcanoi) found on Hispaniola were specialists adapted to dry, open habitats and had a major role in shaping this ecoregion; following a decrease in the extent of these ecosystems after the end of the Pleistocene, these tortoises were restricted to refugia habitats up until their extinction.
