This species has a restricted range in the western Massif de la Selle in Haiti and the Sierra de Baoruco in the Dominican Republic, Hispaniola. Its altitudinal range is from sea level up to 1,061m asl.
Habitat and Ecology
An inhabitant of closed mesic broadleaf forests, as well as shade-grown coffee and cacao plantations, this is a very specialized burrowing species, with males calling from constructed underground chambers and the eggs being laid underground.
It can be locally uncommon and is patchily distributed.
The main threat to this species is habitat loss: the forest of Baoruco is severely threatened by expanding agriculture and cattle grazing, even within Parque Nacional Sierra de Baoruco.
Although it occurs in Parque Nacional Sierra de Bahoruca and Parque Nacional Sierra Bahoruca Oriental in the Dominican Republic, there is a need to greatly strengthen and improve the management of these protected areas to ensure more effective protection of the broad-leaf forest habitat within these areas.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in Hispaniola.
