False canyon mouse


The false canyon mouse or Coronados deer mouse, ("Peromyscus pseudocrinitus") is a species of rodent in the family Cricetidae. It is known only from Coronados Island, a small island in the Gulf of California, part of Baja California Sur, Mexico. The species is threatened by predation by feral cats, and the IUCN has assessed its conservation status as "critically endangered". The false canyon mouse grows to a total length of about including a tail of . The dorsal fur is greyish-black glossed with cinnamon

' by the International Union for the Conservation of Nature (IUCN), the IUCN conservation status for the species is 'vulnerable'. The name "Pseudomys" comes from the combined form of the Greek word "pseudes" (meaning "false") and the Latin word "mys" (meaning "mouse"), presumably because of the plains rat's puzzling similarities and differences to "true mice" in the genus "mus". The name "australis" comes from the Latin word "australis" (

A subsequent study gave cautious hope for a continuing recovery of the population from an all-time low of merely some dozens of pairs in the 1930s. Indeed, it appears as if the species' numbers have been underestimated in more recent years as an accurate census is difficult due to the rugged terrain of its island home. Consequently, the conservation status of this species was downgraded to vulnerable in

Island Conservation has therefore focused its efforts on islands with species categorized as Critically Endangered and Endangered on the IUCN's Red List. Working in partnership with local communities, government management agencies, and conservation organizations, Island Conservation develops plans for, and implements the removal of, invasive alien species, and conducts field research to document the benefits of the work and to inform future projects.

The conservation status of "N. mikei" is listed as Vulnerable on the IUCN Red List, based on an assessment carried out in 2000. This agrees with an informal assessment made by Charles Clarke in 2001, who also classified the species as Vulnerable based on the IUCN criteria. However, Clarke noted that since substantial populations of "N. mikei" lie within protected areas, they "are unlikely to become threatened in the foreseeable future".

Data deficient


A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance:
