California’s 891 pronghorn records belong to two pieces of the state’s wide-open country. Carrizo Plain National Monument, in San Luis Obispo County’s grassland, holds the single largest cluster, while Lassen, Modoc, and Plumas counties carry the sagebrush plateau herds of the far northeast.
Built for distance, not cover
A pronghorn survives on open ground, where its enormous eyes and unmatched speed, the fastest sustained running of any North American land mammal, take the place of hiding cover. That is why California’s record hugs the two landscapes that still offer such room. Carrizo Plain National Monument and neighboring California Valley keep the last big sweep of San Joaquin grassland, while the northeast’s sagebrush flats, including Ash Creek Wildlife Area, resemble the pronghorn’s Great Basin heartland more than anything else in the state.
A spring of fawns and green forage
Records climb from March and crest in May and June, the season when fresh growth draws herds onto open flats and does give birth, usually to twins, out on the range. Young fawns lie low for their first weeks, so a spring pronghorn is often a motionless shape in the grass until it is old enough to run with the herd. Counts ease through late summer and reach their low in December.
Status in California
NatureServe ranks the pronghorn S3, Vulnerable, in California, a long step down from its global G5 standing, reflecting how little of the state’s original open range remains. The species is native here, and USGS NAS does not list it as nonindigenous.
