Population Trend:	Decreasing

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.
Systems:	Terrestrial
