Species Range
The Stephen's kangaroo rat's entire geographic range, estimated at 2870 sq km (1100 sq mi), is centered in the San Jacinto and Perris Valleys of western Riverside County, California, USA, with minor extensions south into San Diego County and north into San Bernardino County. It is known to inhabit annual grassland with sparse perennial vegetation in the San Jacinto Valley and adjacent areas of western Riverside and northwestern San Diego County. A previously unknown population of the kangaroo rat was discovered in the Ramona Valley, San Diego County, in October 1997.
