Conifer forests in a glade-like setting are present over much of these potential additions. Other areas feature steep narrow canyons with year-round streams with abundant streamside vegetation. The potential additions to this world-famous wilderness include the headwaters of Alamo and Piru Creek. This area is habitat for ten sensitive species including the coast horned lizard, endangered arroyo toad, California red-legged frog, southwestern willow flycatcher, least Bell’s vireo, Mount Pinos onion, and prairie falcon, among others. Other animal species found here include black bear, mule deer, bobcat, and mountain lion. As with other potential additions, it provides important habitat for the California condor. The additions would add to the existing Sespe Wilderness, which contains the Sespe Condor Sanctuary.
