Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(iii,v) ver 3.1

Date Assessed: 2006-01-31
Assessor(s): Manuel Acevedo, Eric Smith
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Critically Endangered because its Extent of Occurrence is less than 100km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in eastern Guatemala, and a projected decline in the number of mature individuals from the effects of chytridiomycosis.
Previously published Red List assessments:
2004 Endangered (EN)

Threats [top]

Major Threat(s): The major threats to this species include habitat loss due to expanding agriculture, wood extraction, and human settlement, and water pollution. Chytridiomycosis is also a potential threat, and declines due to the disease have already been detected amongst other species of this genus in Guatemala (Mendelson et al. 2004).

Conservation Actions [top]

Conservation Actions: This species has not been found in any protected area, though one has been proposed within its range. In view of the severe risk of chytridiomycosis, the status of this species should be closely monitored, and ex-situ populations might need to be established.
