Peromyscus dickeyi
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Peromyscus dickeyi faces severe threats from habitat destruction due to agricultural expansion and urban development on San Pedro Nolasco Island. The species' extremely limited range makes it vulnerable to introduced predators, particularly feral cats and rats that compete for resources and prey on juveniles. Climate change poses additional risks through altered precipitation patterns affecting the island's fragile desert scrub ecosystem.
Habitat
This endemic deer mouse inhabits the arid desert scrub and rocky outcrops of San Pedro Nolasco Island in the Gulf of California, Mexico. The species occupies areas with sparse vegetation dominated by cacti and drought-resistant shrubs, typically at elevations below 300 meters.
