Overview

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

Peromyscus pseudocrinitus faces severe threats from habitat destruction due to agricultural expansion and urban development within its extremely limited range. The species' small population size makes it particularly vulnerable to stochastic events and genetic bottlenecks. Mining activities and infrastructure development have further fragmented the remaining suitable habitat, while invasive plant species alter the native vegetation communities this mouse depends upon.

Threat summary

Habitat

This critically endangered mouse inhabits arid shrubland and desert scrub ecosystems, typically favoring areas with sparse vegetation and rocky substrates. The species shows preference for specific microhabitats with particular soil types and elevation ranges within its restricted geographic distribution.

Frequently asked questions

Why is Coronados Deer Mouse classified as Critically Endangered?
Coronados Deer Mouse 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. Peromyscus pseudocrinitus faces severe threats from habitat destruction due to agricultural expansion and urban development within its extremely limited range. The species' small population size makes it particularly vulnerable to stochastic events and genetic bottlenecks. Mining activities and infrastructure development have further fragmented the remaining suitable habitat, while invasive plant species alter the native vegetation communities this mouse depends upon.
Where does Coronados Deer Mouse live?
Coronados Deer Mouse occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
