Jawbone - Butterbread ACEC This vast Area of Critical Environmental Concern (ACEC) lies in the region where the Sierra Nevada grades into the Tehachapi Mountains. It includes all of the Jawbone Canyon – Cross Mountain Area and abuts Red Rock Canyon . The Jawbone – Butterbread – Dove Spring – Lone Tree Canyon complex contains a highly diverse faunal assemblage. Vegetation in the eastern portion is dominated by creosote bush scrub with Larrea tridentata and salt-bush, Atriplex spp. There is some Joshua tree woodland with Yucca brevifolia and, in the upper canyon drainages, juniper, Juniperus californica. In the southern portion the area is dominated by chaparral with scrub oak, Quercus turbinella, big sage, Artemisia tridentata, mountain mahogany, Cercocarpus intricatus, and buckwheat, Eriogonum fasciculatum. Pinyon pine, Pinus monophylla, and gray pine, Pinus sabiniana, occur in the higher portions in the west. Several rare plants are found here including Chorizanthe spinosa, Hemizonia arida, Phacelia nashiana, Pholisma arenarium and Petalonyx nitidus. Animals are numerous and abundant. Of note are the reptiles, of which 38 species have been observed including the desert tortoise, Gopherus agassizi, chuckwalla, Sauromalus obesus, Western blind snake, Leptotyphlops humilis, Mojave patch-nosed snake, Salvadora hexalepis mojavensis, Mojave glossy snake, Arizona elegans candida, Mojave shovel-nosed snake, Chionactis occipitalis, and Mojave rattlesnake, Crotalus scutulatus. Over 160 species of birds have been recorded in the area including such species as golden eagle, Aquila chrysaetos, prairie falcon, Falco mexicanus, yellow-billed cuckoo, Coccyzus americanus, California quail, Lophortyx californicus, Gambel's quail, Lophortyx gambelii, and mountain quail, Oreortyx pictus. Among the mammals present are such larger species as desert kit fox, Vulpes macrotis, bobcat, Lynx rufus, badger, Taxidea taxus, mountain lion, Felis concolor, black bear, Ursus americanus, and California bighorn sheep, Ovis canadensis californiana. Integrity: Portions of the area have been virtually denuded of vegetation and severely compacted by off-road-vehicle activity, particularly in Jawbone Canyon. The more inaccessible portions and higher parts are relatively undisturbed. Use: Research, educational, observational. Some private. May 1982 Kern |
