It occurs from the Front Range of Colorado through Utah, northern New Mexico and Arizona to the White Mountains of California along the Nevada border in the west. Bristlecone pine commonly occurs in small open groves on arid slopes, but it also grows in association with limber and ponderosa pines, white fir, Douglas - fir, and Engelmann spruce, generally above the 8000 -foot level. This tree has little economic value as a timber species, but does provide a protective and beautifying cover to the landscape. A newly -acquired interst in bristlecone pine stems from the discovery that these trees reach tremendous ages. -

Monsoon Passage Fact Sheet
Monsoon Passage Fact Sheet Safe haven stepping stones from the Mojave Desert to the Northern Great Basin East Pass a few years after a fire in the Clover Mountains of the southern Great Basin looking down into the Mojave’s Tule Desert © Louis Provencher/TNC Monsoon Passage The connected mountain ranges and wet valley bottoms of this natural highway provide desert tortoises, bighorn sheep, Cooper’s hawk, mule deer and other species escape routes from growing climate impacts, allowing them to find new homes where they can thrive. The region's name comes from being at the western edge of the summer monsoons that provide needed eastern-facing moisture to buffer rising temperatures and a pathway for species moving north. Imagine populations of raptors, small carnivores, small mammals, mule deer, bighorn sheep, passerine birds, insects, and plant species pushed northward or up and around mountains by warming temperatures and changes in precipitation patterns. Non-migratory species flow from the hot Mojave Desert ecoregion to the cooler Columbia Plateau ecoregion passing through the entirety of the Great Basin ecoregion is not easily guaranteed. There are less than five corridors of passably connected mountains ranges and wet valley bottoms that fully allow species movement within a viable thermal environment that may be viewed as steppingstones of safe havens. The Nevada Chapter is proposing one such thermal corridor in eastern Nevada titled Monsoon Passage. The corridor follows the Nevada-Utah border and is mostly in Nevada. For those familiar -

Conservation Management Strategy Coyote Springs Desert Wildlife Management Area
Conservation Management Strategy Coyote Springs Desert Wildlife Management Area Clark County, Nevada February 2007 EXECUTIVE SUMMARY The Mojave Desert population of desert tortoises has been declining since the 1970s and was declared threatened under the Federal Endangered Species Act (ESA) in 1990. Impacts of urban growth, agriculture, recreation, and other human activities—coupled with the rise of predators and disease—are thought to be the major causes of tortoise decline. Over the past 16 years, several attempts to define and implement specific Conservation Actions (CAs), strategies, and plans have been proposed to protect the tortoise and other species considered imperiled. Clark County and the U.S. Fish and Wildlife Service (USFWS) entered into the Multiple Species Habitat Conservation Plan (MSHCP) as a binding commitment to protect 78 species, including the tortoise, by providing a commitment to implement specific CAs. Subsequent to the MSHCP, a site-specific conservation management strategy (CMS) is required for each of four areas in Clark County known as Desert Wildlife Management Areas (DWMAs). The intent of the CMS is to guide management actions and to unite federal, state, and local agencies in coordinated, adaptive management for each DWMA. This document is a CMS for the Coyote Springs DWMA, which encompasses the Desert National Wildlife Refuge, Coyote Springs Investment, and Coyote Springs area of critical environmental concern (ACEC), and is almost entirely preferred desert tortoise habitat of creosote- bursage vegetation on gentle plains and bajadas. Along its northern boundary, a large residential and resort development has the potential to impact conservation efforts. Construction of roads and utility rights-of-way (ROWs), as well as increased human activity, may introduce serious threats to the future viability of desert tortoise populations in the DWMA. -
