Threats [top]

Major Threat(s): This species is threatened by habitat loss due to agriculture and pastureland expansion, charcoal production and wood harvesting. Although it has been found in disturbed areas it is always associated with forest pockets.

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for this species. Further research into its distribution, abundance, and population trends should be carried out to have more knowledge about how the threats are impacting the species. It is found in Sierra de Bahoruco National Park but currently it is ineffective in protecting the forest against deforestation. Effective protected area management is needed to ensure the survival of this and other species on Hispaniola.
