Jico Deer Mouse

Habromys simulatus

Declining

Overview

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

Habromys simulatus faces severe population decline due to extensive deforestation and agricultural conversion throughout its limited montane forest range in Mexico. The species' specialized habitat requirements make it particularly vulnerable to forest fragmentation, as it depends on mature cloud forest ecosystems that are rapidly disappearing. Climate change poses an additional threat by altering the temperature and moisture conditions essential for maintaining the cloud forest environment this mouse requires.

Threat summary

Habitat

This species inhabits montane cloud forests and pine-oak forests at elevations between 1,800-3,000 meters in the mountains of central Mexico. It requires mature forest with dense canopy cover and high humidity levels typical of cloud forest ecosystems.
