This species is now restricted to Tortola, Virgin Gorda and Great Dog in the British Virgin Islands, having been extirpated from St. John in the U.S. Virgin Islands. It has been recorded from sea level up to 227m asl.
Habitat and Ecology
It is found in dry scrub forest in terrestrial bromeliads, and has not been recorded outside forested areas. Males call from near to the ground and terrestrial bromeliads; eggs are laid in bromeliads, and breeding is by direct development.
This species appears to be declining wherever Osteopilus septentrionalis spreads. The Great Dog population is somewhat distinct, extremely limited in range, and very susceptible to development there (Perry and Gerber, 2006).
Infrastructure development for tourism, human settlement, and road construction is a major threat. Rats and mongooses have also been introduced to the island and most likely pose a threat.
It was previously known from a protected area on St. John, and it may occur in Virgin Gorda Peak Forest Park. The habitat of this species on Tortola and Virgin Gorda requires improved protection, and there is also a need to control invasive predators. Further survey work is needed to determine the current population status of this species.
Red List Status
Listed as Endangered because its Extent of Occurrence is much less than 5,000km2, its area of occupancy is less than 500km2, its range is severely fragmented, and there is ongoing decline in the quality of its habitat in the British Virgin Islands.
