Craugastor nefrens

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Craugastor nefrens faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development in its limited montane 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 cool, moist conditions essential for this species' survival in cloud forest environments.

Threat summary

Habitat

This species inhabits montane cloud forests and humid pine-oak forests at elevations between 1,200-2,400 meters in the mountains of Guatemala and southern Mexico. It requires cool, moist microhabitats with abundant leaf litter and moss cover, typically found near streams or in areas with persistent fog and high humidity.
