Sierra Juarez Treefrog

Sarcohyla sabrina

Declining

Overview

Sarcohyla sabrina, also known as the Sierra Juarez treefrog, is a species of frog in the family Hylidae. It is endemic to the northern slopes of Sierra de Juárez in northern Oaxaca, Mexico. The specific name sabrina is Latin for river nymph and refers to the close association of this species with streams.

Sarcohyla sabrina faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development in its limited montane forest range. The species is particularly vulnerable to chytrid fungal infections, which have devastated amphibian populations throughout Central America. Climate change poses an additional threat by altering the temperature and humidity conditions essential for this cloud forest specialist.

Threat summary

Habitat

This species inhabits montane cloud forests and pine-oak forests at elevations between 1,200-2,400 meters in the Sierra Madre Oriental of Mexico. It requires humid microhabitats with permanent water sources for breeding, typically found near streams and temporary pools within dense forest canopy.
