Scientific Name: Plectrohyla sagorum Hartweg, 1941

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2009-01-06
Assessor(s): Georgina Santos-Barrera, Luis Canseco-Márquez, Manuel Acevedo
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in Guatemala, El Salvador and Mexico.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species occurs on the Pacific slopes of the Sierra Madre del Sur de Chiapas, south-central Chiapas, Mexico, south-west to Guatemala and again in northern El Salvador (not mapped here), from 1,000-2,050m asl.
Countries occurrence:
Native:
El Salvador; Guatemala; Mexico
Additional data:

Population [top]

Population:It is abundant in two localities in the Cuchumatanes, Guatemala. It is very rare in Mexico, where it is known from a single locality. Only one specimen is known from El Salvador.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This stream-breeding amphibian exists only in cloud forests.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The main threat to the species is habitat loss due to deforestation and transformation of the original forest habitats in both southern Chiapas and Guatemala for agriculture, logging, timber plantations, and human settlement. Since this is a relatively high-elevation, stream-breeding species, chytridiomycosis is a potential future threat, and has already led to declines in other species in this genus in Central America.

Conservation Actions [top]

Conservation Actions: It is present in the Reserva de la Biósfera El Triunfo (Mexico) where a well-preserved forest still exists, but is not known from any protected areas in Guatemala, and there is a need for improved protection of suitable habitats for this species. Further survey work is needed to determine the status of populations in Mexico and El Salvador, and to assess the risk posed by chytrid.
