Habitat and Ecology [top]

Habitat and Ecology:This species can be found in xerophytic montane areas and pine-oak forest (Genoways 1971 in Dominguez-Castellanos and Ortega 2003). Weeds, low brush, cornfields, grass, and several trees compose the typical habitat of the Jaliscan spiny pocket mouse (Genoways 1973 in Dominguez-Castellanos and Ortega 2003). Some specimens were caught in the immediate vicinity of a highway (Dominguez-Castellanos and Ortega 2003). Current agricultural use has greatly modified the landscape (Genoways 1971 in Dominguez-Castellanos and Ortega 2003).

The biology and ecology of this species is poorly known.

Threats [top]

Major Threat(s): The species is reported as having a small range that is subject to increasing habitat disruption (Nowak 1999). The pine-oak forest in this region is severely fragmented due to timber extraction.

Conservation Actions [top]

Conservation Actions: This species is protected under Mexican Law (NOM-059-ECOl-2001).
