Critical habitat for the Peninsular bighorn sheep (Ovis canadensis).

Critical Habitat for the Peninsular Bighorn Sheep (Ovis canadensis) Approximately 875,613 acres (354,343 hectares) in Riverside, San Diego, and Imperial counties in southern California were proposed on July 5 as critical habitat for this endangered population of bighorn sheep. It inhabits the Peninsular Mountain Ranges from the San Jacinto Mountains south to the Volcan Tres Virgenes Mountains in Baja California, Mexico. The sheep occur mostly on open slopes in the hot, dry desert regions where the land is rough, rocky and sparsely vegetated. During the dry months, the sheep tend to gather near sources of water.
