Thorius grandis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Thorius grandis faces severe population decline due to extensive deforestation and agricultural conversion throughout its limited montane cloud forest range in Mexico. The species' extremely restricted distribution makes it particularly vulnerable to habitat fragmentation, while climate change threatens to shift the cool, humid conditions essential for this moisture-dependent salamander. Chytrid fungal disease, which has devastated amphibian populations across Mesoamerica, poses an additional existential threat to remaining populations.
Habitat
Thorius grandis inhabits montane cloud forests at elevations between 2,000-3,000 meters in the Sierra Madre Oriental of Mexico. These salamanders require the cool, consistently humid microhabitats found under logs, rocks, and leaf litter in pristine cloud forest environments.
