Assessment Information [top]

Red List Category & Criteria: Critically Endangered A2ae; B2ab(i,ii,iv,v) ver 3.1
Year Published: 2010
Date Assessed: 2008-12-19
Assessor(s): Ariadne Angulo
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Critically Endangered because of a drastic population decline, estimated to be more than 80% over the last three generations, inferred from the apparent disappearance of most of the population (no individuals have been reported over the last 20 years), perhaps due to a combination of any of these factors: climate change and/or chytridiomycosis, limited distribution, habitat destruction, forest fragmentation, and high habitat specialization. Its Extent of Occurrence is also less than 10km2.
2008 Critically Endangered
2004 Critically Endangered
1996 Data Deficient

Population [top]

Population: This species has not been seen since 1981, and it is now possibly extinct. Extensive surveys of suitable habitat have failed to find any individuals. It has clearly undergone a catastrophic decline.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species has been recorded from bromeliads (terrestrial and arboreal) in forests and open and rocky areas. It is known to be a live-bearing species, giving birth to 1-3 young, unique amongst members of the genus.
Systems: Terrestrial

Threats [top]

Major Threat(s): While the cause(s) for decline in this species remain(s) unknown, suspected factors include habitat destruction, forest fragmentation, limited distribution (10 km2), high habitat specialization, slow reproduction, climate change, chytridiomycosis and introduced predators.

Conservation Actions [top]

Conservation Actions: The range of this species includes Carite Forest Reserve, which is a well-managed protected area. Further surveys are needed to relocate this species and determine whether or not it might still survive in the wild. In view of the severe risk of chytridiomycosis, surviving individuals might need to form the basis for the establishment of an ex-situ population.
