Assessment Information [top]

Red List Category & Criteria:

Critically Endangered D ver 3.1

Year Assessed:

2008

Assessor/s

Álvarez-Castañeda, S.T., Castro-Arellano, I. & Lacher, T.

Evaluator/s:

McKnight, M. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)

Justification:
Listed as Critically Endangered (Possibly Extinct) because this species has not been recorded since 1986 despite exhaustive surveys and it might already be extinct. Should this species be located, it is likely to be very few in number. Over the past 20 years its habitat has been completely destroyed for agricultural activities, and this species is very specific to these deep agricultural soils.

History:

1996	–	Endangered (Baillie and Groombridge 1996)
1994	–	Endangered (Groombridge 1994)
1990	–	Endangered (IUCN 1990)
1988	–	Endangered (IUCN Conservation Monitoring Centre 1988)

Population [top]

Population:	There is no information on population or abundance. This species has not been recorded since 1986, despite exhaustive surveys. This species may be extinct.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	This species is found on cactus-covered slopes and in contiguous areas with short vegetation and little topographic relief; the southern populations inhabit floodplains and relatively flat areas bordered by mesas and hills. It uses burrows that are not located under vegetation. The species apparently possesses a high affinity for flat land and a lack of tolerance for cultivation. It is nocturnal. Young are born during several months of the year, but the peaks appear to be in winter and spring (Best and Lackey 1985).
Systems:	Terrestrial
