Scope of the Wilderness Management Plan This plan provides the primary management guidance for the Muddy Mountains Wilderness. The plan also addresses some actions outside the wilderness area, including wilderness access and information provided to the public. This plan is jointly prepared by the Bureau of Land Management and National Park Service. Each agency has jurisdictional authority for separate portions of the wilderness. The plan is anticipated to address management over the next 10 years. The plan 1) identifies the conditions and opportunities which will be managed within the wilderness; 2) creates specific guidance for managing the resources and activities existing in the wilderness; and, Anniversary Narrows 3) preserves the area’s wilderness characteristics cumulatively identified as Wilderness areas provide a contrast to lands untrammeled quality, outstanding where human activities dominate the opportunities for solitude or a primitive form landscape.

It has occupied a criti- cal structural position in the western Cordillera since Mesozoic time. In the Cretaceous through early Tertiary, it stood just east and north of major fold and thrust belts and also marked the northern end of a broad, gently (~15o) north-plunging uplift (Kingman arch) that extended southeastward through much of central Arizona. Mesozoic and Paleozoic strata were stripped from the arch by northeast-flowing streams. Peraluminous 65 to 73 Ma granites were emplaced at depths of at least 10 km and exposed in the core of the arch by earliest Miocene time. Calc-alkaline magmatism swept northward through the northern Colorado River extensional corridor during early to middle Miocene time, beginning at ~22 Ma in the south and ~12 Ma in the north.

Determination of the areal distribution, geochronology, lithology, geochemistry, and internal stratigraphy of the TBS is important for its establishment as a reliable stratigraphic reference horizon for tectonic reconstructions of the extensional corridor during the middle Miocene.

The plan proposes to establish burro free areas within the park and to accept a certain amount of burro use in areas according to National Park Service prescriptions. The plan also proposes no range expansion or new use by burros, removal of burros from areas where they pose a resource threat or public safety hazard, and fencing sections of the park as opportunities arise. Summary of Environmental Impact and Adverse Environmental Effects: The adverse impacts to the ecosystems by feral burros would be eliminated or reduced to allow the recovery of park resources and to minimize or prevent burros from interfering with natural processes and the perpetuation of natural features and native species.

    Birds AMERICAN PEREGRINE FALCON Falco peregrinus anatum Covered Species Family Falconidae (Falcon Family) Gerald & Buff Corsi/CalPhoto Gerald & Buff Description: The American peregrine falcon is a medium-sized raptor, total length 41 - 51 cm (16 - 20 in.). Adults have a dark gray back and crown, dark bars or streaks on a pale chest and abdomen, and heavy malar (cheek) stripes on the face. Young birds, prior to first molt, are brownish above and underparts streaked vertically with brown. Nesting season from March to June; clutch size 3 - 4 eggs; incubation approximately 33 days; only 2 - 3 chicks hatch and fledge 42 days later. Diet: Peregrines prey almost exclusively on medium-sized birds (pigeons, doves, ducks, swifts, and others), and occasionally on bats. It hunts for its food by diving after the prey and catching it mid-air. Habitat: Peregrines inhabit mixed conifer, pinyon-juniper, sagebrush, lowland riparian, and grassland habitats, as well as agricultural and urban areas. Nests are shallow hollows in soil, rock ledges, small caves on high cliffs, old raptor nests, or tree cavities. These falcons also are known to nest on various man-made structures within the Las Vegas Valley. Range: Known throughout the southern half of North America. In Clark County, Nevada, known from the Spring Mountains, Desert National Wildlife Range, Logandale, Overton State Wildlife Management Area, and Newberry Mountains. Known to nest in the Black Mountains, Lake Mead area, and within the Las Vegas Valley area. Special Remarks: The American peregrine falcon was removed from the Federal list of endangered species on August 25, 1999; the species will be monitored for at least 13 years.
