Overview

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

Ixalotriton parvus faces severe threats from habitat destruction due to agricultural expansion and logging activities in its limited montane forest range. The species' extremely restricted distribution makes it particularly vulnerable to local environmental changes, while climate change poses additional risks by altering the cool, humid conditions essential for its survival. Water pollution from agricultural runoff and human settlements further degrades the pristine stream habitats this salamander requires for reproduction.

Threat summary

Habitat

This critically endangered salamander inhabits cool, humid montane forests at elevations between 1,800-2,400 meters in the Sierra Madre Oriental of Mexico. It requires pristine mountain streams and adjacent leaf litter in cloud forest environments with consistent moisture and stable temperatures.
