California Pronghorn Bodie-Wassuk Migration Stopovers

Metadata Updated: January 22, 2026

The Bodie-Wassuk pronghorn (Antilocapra americana) herd contains migrants, but this herd does not migrate between traditional summer and winter seasonal ranges. Therefore, annual ranges were modeled using year-round data to demarcate high use areas instead of modeling the specific winter ranges commonly seen in other ungulate analyses in California (for example, see the “Casa Diablo Mule Deer” section of this report). Though the Bodie-Wassuk pronghorn aren’t traditional migrants, much of the herd displays a somewhat nomadic migratory tendency, moving between the Bodie Hills east of U.S. Highway 395 in California to a basin west of the Wassuk Range between Aurora Crater and Corey Peak in Nevada. A few collared individuals moved as far north as the Gray Hills, staying west of the Wassuk Range, and one collared individual moved as far south as the Alkali Valley. This herd prefers low sagebrush (Artemisia arbuscula) habitat followed by big sagebrush (Artemisia tridentata) communities. Pronghorn were reintroduced just north of Mono Lake beginning in the 1940s as well as to the Adobe Valley in the 1980s, but low fawn recruitment due to marginal habitat quality, a lack of permanent water availability, abundant wildlife exclusion fencing, and the expansion of pinyon-juniper woodlands and invasive cheat-grass (Bromus tectorum) into preferred native shrub and forb habitats has prevented population growth. The current estimate is stable at <150 animals (Taylor, 2011). Additional conservation concerns for the herd include human activities, such as off-highway vehicle use and proposed mining, as well as an increasing wild horse population. These mapping layers show the location of the migration stopovers for pronghorn (Antilocapra americana) in the Bodie-Wassuk population in California. They were developed from 102 migration sequences collected from a sample size of 18 animals comprising GPS locations collected every 4 hours.
