This species has a restricted and fragmented range in central Jamaica, where it has been recorded from 120-880m asl.
Habitat and Ecology
It is found in bromeliads in pine and deciduous forests. Eggs are laid in bromeliads. It was thought not to have a call until recently as it does not have a vocal sac, but it actually does vocalize by means of vibration. It is restricted to old growth forest, and is not tolerant of disturbance of its forest habitat.
This species appears to be less common than Osteopilus wilderi.
Deforestation is a major threat throughout its range, primarily for agriculture, human settlement, development for tourist activities, and selective logging.
It is known from a few forest reserves, but these do not guarantee the species' long-term protection, and increased management of these reserves, and improved habitat protection, are necessary.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its range is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat on Jamaica.
