Brown-streaked Salamander

Pseudoeurycea mixcoatl

Declining

Overview

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

Pseudoeurycea mixcoatl faces severe threats from habitat destruction due to agricultural expansion and urban development in its restricted montane range. The species' extremely limited distribution makes it particularly vulnerable to local environmental changes, while deforestation for cattle grazing and crop cultivation continues to fragment its cloud forest habitat. Climate change poses an additional threat by altering the moisture regimes essential for this salamander's survival.

Threat summary

Habitat

This salamander inhabits cloud forests and pine-oak forests in montane regions of central Mexico, typically found under logs, rocks, and leaf litter in moist microhabitats. It requires cool, humid conditions with consistent moisture levels characteristic of high-elevation forest ecosystems.

Frequently asked questions

Why is Brown-streaked Salamander classified as Critically Endangered?
Brown-streaked Salamander 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. Pseudoeurycea mixcoatl faces severe threats from habitat destruction due to agricultural expansion and urban development in its restricted montane range. The species' extremely limited distribution makes it particularly vulnerable to local environmental changes, while deforestation for cattle grazing and crop cultivation continues to fragment its cloud forest habitat. Climate change poses an additional threat by altering the moisture regimes essential for this salamander's survival.
Where does Brown-streaked Salamander live?
Brown-streaked Salamander occurs in Mexico. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Brown-streaked Salamander?
The main threats to Brown-streaked Salamander are 2.1, 2.3, 5.1, and 5.1.1. The full IUCN-classified threat record for this species is detailed on the species page.
