The mountainous terrain has deep, winding, open and expansive canyons, many of which contain springs with extensive riparian vegetation. This area is a transition zone between the Great Basin, Mojave Desert and Sierra Nevada ecoregions. Vegetation varies considerably with a creosote desert scrub community on the bajadas, scattered yuccas, cacti, annuals, cottonwood and oak trees in the canyons and valleys and a juniper-pinyon woodland with sagebrush and digger/gray pine on the upper elevations.
Wildlife includes mule deer, golden eagle and prairie falcon. Evidence of occupation by prehistoric peoples has been found throughout the wilderness.
The Pacific Crest Trail passes through the wilderness along the crest and western side.
Area restoration
Starting in 1992, an ongoing effort to restore the environment in both the Kiavah and Owens Peak wilderness areas is being conducted by the University of California, Davis, Student Conservation Corps. By March 1997, 15 miles (24 km) of closed roads had been restored by relieving soil compaction with hand tools or a dozer-drawn ripper, installing waterbars, placing vertical mulch (woody debris and rocks) and scarifying disturbed area surfaces to increase water absorption and seed collection. Despite continued monitoring, illegal off-highway vehicle (OHV) use is a problem in some areas.[3]
