Assessment Information [top]

Red List Category & Criteria: Endangered A4ae; B1ab(v) ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Ariadne Angulo
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Endangered because of a population decline estimated to be greater than 50%, over a ten year period including the past and the future, perhaps from the effects of climate change and/or chytridiomycosis; and because it also has an Extent of Occurrence less than 5,000km2, its distribution is severely fragmented, and there is continuing decline in the number of mature individuals, in Puerto Rico.

Population [top]

Population:Studies show that populations of this species are declining in both the higher and lower elevations of its range (R. Joglar pers. comm.).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a terrestrial species, occurring in mesic upland forest, and has not been recorded outside forest habitat. Males call from low vegetation, and breeding is by direct development.

Threats [top]

Major Threat(s): Although some habitat destruction is taking place (due to agriculture and infrastructure development for roads and human settlement), the primary reason for the observed declines is believed to be chytridiomycosis (acting in combination with climate change).

Conservation Actions [top]

Conservation Actions: It occurs in several protected areas, most of which are well managed. Further research is necessary to determine the reasons for the species' decline.
