Cadiz Valley Description/Location: North of Hwy 62, south of Hwy 40 between the Sheep Hole mountains to the west and the Chemehuevi ACEC to the east.
Nationally Significant Values: Ecological: The Cadiz Valley contains an enormous variation of Mojave vegetation, from Ajo Lilies to Mojave Yucca. Bighorn, deer and mountain lion easily migrate between basin and range mountains of the Sheephole, Calumet Mountains, Iron Mountains, Kilbeck Hills and Old Woman Mountains with little or no human infrastructure limits.
Cultural: Remnants of the ranching, mining and railroad activities of the late 19th and early 20th century are evident in the presence of Route 66, old homesteads, cemeteries, stamp mill and mining sites located within the area.
Scientific: Geological studies occur along the Barstow‐Bristol trough a conspicuous west‐northwest trending physiographic feature which straddles the boundary between the Mojave and Sonoran tectonic blocks is adjacent to the area.
Mgmt. Plan/Date of Designation: New Proposal
Relevance and Importance Criteria: Relevant biological resources including wildlife and plant assemblages. The area is critical for bighorn sheep, Mojave fringed toed lizards, desert tortoise, burrowing owl and several bat species. Additionally, numerous rare and sensitive plants have major populations in the valley, making the area regionally significant.
Goals: Protect biological values, including habitat quality, populations of sensitive species, and landscape connectivity while providing for compatible public uses.

Alternatives: Under All Action Alternatives—This area (size and location vary between alternative, see table above and maps that follow) would be identified as an ACEC and/or Wildlife Allocation Area.
No Action – this conservation area would not exist, as it does not exist currently.
Objectives (desired future conditions)/Allowable Uses/Management Actions Resource Program Objective: Maintain or Improve condition of vegetation Vegetation (incl. special Management Action: Remove invasive plants, rehabilitate/revegetated status species) disturbed areas. Management Action: Protect populations of special status plants and rare natural communities.
Cadiz Dunes Psammophytic Plant Community UPA Special Status Species: Nelson Desert Bighorn Sheep Fish and Wildlife (incl. Management Action: Evaluate water sources and determine if artificial water special status species) sources should be developed. Special Status Species: Desert Tortoise Management Action: Maintain viable populations and connections between other ACECs and critical habitat. Special Status Species: Mojave fringed toed lizard Management Action: Maintain viable populations; ensure connectivity between occupied habitat Protect habitat and source of sand.
Objective: Provide for the use of a designated system of Ground Trails and Travel Transportation Linear Features to ensure access to the public for appropriate Management uses. Management Action 1: All legal open roads and trails will be signed including road or trail number/name. Management Action 2: All roads and trails identified as closed will be rehabilitated/restored. Management Action 3: Restore all undesignated roads or trails. Management Action 4: Provide routine maintenance of the designated roads and trails system including installation of routine signs, markers, culverts, ditches, water bars, barriers, gates, or cattle guards on/or adjacent to system roads and trails.
Objective: Consolidate resource management Rights of Way Management Action: Acquire all inholdings from willing sellers Not an allowable use. Renewable energy development is not compatible with Renewable Energy NLCS and ACEC unit values and criteria
Geothermal: Area is closed to geothermal leasing and development There are important salt and mineral deposits in dry lake beds within this Locatable Minerals region. Mineral Materials Open mineral entry w/ stipulations Non‐Energy Leasables
