Scientific Name:	Charadrahyla nephila

Assessment Information [top]

Red List Category & Criteria:	Vulnerable B1ab(iii) ver 3.1
Year Published:	2004
Assessor/s:	Georgina Santos-Barrera, Luis Canseco-Márquez
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Contributor/s:
Justification: Listed as Vulnerable because its Extent of Occurrence is less than 20,000km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in Oaxaca and Veracruz, Mexico.

Geographic Range [top]

Range Description:	This species is known from Sierra de Juárez and Sierra Mixe, north-central Oaxaca, Mexico. A specimen has also been collected from Los Tuxtlas, Veracruz, Mexico, but this record is in doubt. It probably occurs more widely than records suggest. It occurs at elevations of 680-2,256m asl.
Countries:	Native: Mexico

Population [top]

Population:	This is a common species.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It inhabits mesic cloud forest, and is commonly found in or near streams and low vegetation, and presumably breeds in streams.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	The high rate of disturbance of the cloud forest is the main threat to this species. Tadpoles have been found in southern Mexico with loss of keratinised mouthparts, suggesting that chytridiomycosis might be involved.

Conservation Actions [top]

Conservation Actions:	The range of this species does not include any protected areas, and urgent protection of the forests along the Sierra de Juárez and Sierra Mixe is required. The species is in need of close population monitoring, particularly if chytrid is shown to be a genuine threat.
