Ecoregions
Colorado Plateau Ecoregion

Sculpted into a fantastic redrock chaos, the area shared by Utah, Colorado, New Mexico, and Arizona is a product of wind, water, and time.

Still Rugged After All These Years

The Sierra Club seeks permanent protection for the Colorado Plateau's wildlife habitat, its limitless vistas, free-flowing rivers, native woodlands, and untouched wilderness

On Our Agenda

  • Confer federal wild-and-scenic protection on remaining free-flowing rivers.
  • Shift the region's economy away from resource exploitation to sustainable development.
  • Reform the Mining Law of 1872 to prevent the proliferation of new mines and reclaim abandoned mines.
  • Restrict or halt the importation of hazardous and radioactive waste from areas outside the Plateau.
  • Eliminate timber sales that threaten old-growth ponderosa pine stands; do away with subsidized timber sales in all national forests.
  • Protect the Grand Canyon by restricting development on its boundaries; restore its quietude by limiting the number of aircraft overflights.
  • Reform the U.S. Department of Agriculture's Wildlife Services program (nee Animal Damage Control) to prevent the wholesale slaughter of livestock predators.
  • Require federal and state agencies to evaluate the environmental impacts of all proposed development activities.
  • Protect riparian areas from livestock by requiring herd rotations, fencing, and temporary range closures.

The Land

This is desert canyon country. The Colorado River and its tributaries, the Green and the San Juan, have done much of the carving. Along the margins of the Plateau, high, volcanic tablelands rise to more than 11,000 feet, supporting spruce forests, aspen groves, and well-watered meadows. Stands of old-growth ponderosa pine cover mid-elevation slopes.

Population

About 785,000, of whom a sizable number are Native Americans (Ute, Kaibab-Paiute, Navajo, Hopi, Havasupai, Hualapai, Zuni, and Pueblo).

Economy

The extraction of uranium, coal, oil, and gas, along with grazing, electricity production, and logging are the mainstays. A lucrative service industry has emerged to accommodate a growing influx of recreationists.

Seven Hundred Years Ago

The Anasazi people, who had flourished in the Four Corners area for hundreds of years, began to abandon their adobe pueblos and cliff dwellings, for reasons that remain unclear.

Nature Meccas

Bits and pieces of the dazzling puzzle that is the plateau have been afforded varying degrees of protection, notably Grand Canyon, Zion, Canyonlands, Bryce Canyon, Arches, Mesa Verde, and Petrified Forest national parks.

Superlatives

Unprotected canyons near Kanab in southern Utah hold the last relict riparian areas in the state, lush with hanging gardens, tall rushes and grasses, oak, maple, and Douglas fir. Near them is a fragile expanse of coral-pink sand dunes dotted with green islands of ponderosa pine.

Popular Play

Many rafters are drawn by some of the continent's wildest whitewater. Thousands of backpackers, dayhikers, car campers, mountain bicyclists, and rock climbers explore the terrain each year.

Enviroclimate

Some residents--notably miners and ranchers--resent "outside interference," and environmentalists and local wilderness advocates have been hanged in effigy or received death threats. Yet eight out of ten Utahns agree it's important to designate additional wilderness in their state.

Conservation High

In 1956, the Sierra Club, led by David Brower, defeated a proposal to dam the Yampa River at Echo Park in Dinosaur National Monument. In 1968: Brower and the Club prevailed in a campaign to stop dams in the Grand Canyon.

Conservation Low

In 1963 "the place no one knew"--Glen Canyon--was flooded behind a hydroelectric dam, creating the eyesore called Lake Powell. The Sierra Club had traded Glen Canyon, sight unseen, to save Dinosaur.

Progress

The Sierra Club recently played a lead role in developing the Utah Wilderness Coalition's model 5.7-million-acre Utah BLM wilderness proposal, and convinced former Representative Wayne Owens (D-Utah) to craft legislation containing most of the proposal's ideas. The Club also helped secure a BLM recommendation for wilderness designation for 75,000 acres in western Colorado, and it successfully appealed a BLM decision to deforest woodland in Utah's Henry Mountains. Recently the Club initiated a dialogue with the Utah Mountain Bicycling Association to establish mutually agreeable policies and standards for mountain-bike use and to begin a joint rider-education effort.

Biggest Threats

Mining, oil-and-gas drilling, logging, and ranching continue to degrade the ecoregion. Air pollution obscures scenic vistas. Dams reduce fish populations on the Colorado and other rivers. Roads for logging and tourism carve up ecosystems. Hazardous wastes, including radioactive tailings from uranium mines, contaminate water supplies. Vandals and pothunters plunder Anasazi ruins. Off-road vehicles rip up the terrain.

Celebrators

For many, the first name that comes to mind is Edward Abbey. With Desert Solitaire, the irascible iconoclast left such an indelible literary mark that many now refer to the region as "Abbey country."
