About the Mohave Ground Squirrel

The Mohave ground squirrel (Xerospermophilus mohavensis) is a species of ground squirrel found only in the Mojave Desert in California. The squirrel was first described in 1886 by Frank Stephens of San Diego. It is listed as a threatened species under the California Endangered Species Act, but not under the federal Endangered Species Act. The IUCN lists this species as near threatened.

The Mohave ground squirrel measures about nine inches from nose to tail and feeds on leaves and seeds from February to July.

It can occupy Joshua tree woodlands, creosote scrub, saltbush scrub and mojave mixed woody scrub. Typical forage plants are those that meet nutritional and water content requirements. These can include shrubs such as winterfat, spiny... Wikipedia →
