Craugastor trachydermus

Declining

Overview

Craugastor trachydermus is a species of frog in the family Craugastoridae. It is endemic to Guatemala and only known from its type locality, Xiacam in the Sierra de Santa Cruz, Izabal Department, where the type series was collected in 1989. The species might already be extinct. However, specimens collected some 10 km (6.2 mi) from the type locality might belong to this species.

Craugastor trachydermus 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 Guatemala and southern Mexico. It requires cool, moist microhabitats with abundant leaf litter and is typically found near streams or seepages in well-preserved forest areas.

Frequently asked questions

Why is Craugastor trachydermus classified as Critically Endangered?
Craugastor trachydermus is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Craugastor trachydermus 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.
Where does Craugastor trachydermus live?
Craugastor trachydermus occurs in Guatemala. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Craugastor trachydermus?
The main threats to Craugastor trachydermus are 1.1, 2.1, 3.2, and 5.3. The full IUCN-classified threat record for this species is detailed on the species page.
