Protect Grand Canyon Watershed

“Leave it as it is. You can not improve on it. The ages have been at work on it, and man can only mar it.” — President Theodore Roosevelt

Sandwiched between vistas of the Grand Canyon and two national monuments -- Grand Canyon Parashant and Vermilion Cliffs, lies the Grand Canyon watershed region. The heart of this proposed national monument is the North Kaibab Plateau, where the Colorado River carves the Grand Canyon and provides water for millions of people in Arizona, Nevada, and California, and further downstream to Mexico.

The Plateau is home to 22 sensitive plants and animals, some of which found nowhere else in the world, including the Kaibab squirrel. In addition, this area provides critical wildlife corridors for iconic wildlife such as mountain lions and mule deer, and important habitat for imperiled species such as the California condor and the desert tortoise.

Grand Canyon, an American icon and one of the seven natural wonders of the world, and its watershed deserve permanent protection.

Key threats to the area include the following:

  • Uranium mining—Existing and proposed uranium mining continues to threaten the water quality, wildlife, and intact habitat of the Grand Canyon watershed.
  • Lack of room to roam for wildlife—The region lacks safe habitat connections between Grand Canyon National Park and Grand Staircase-Escalante National Monument in Utah.
  • Logging of ancient trees—Lacking permanent protections, the old-growth ponderosa pine forests of the North Kaibab Plateau remain subject to destructive logging, threatening native wildlife diversity and climate resiliency.
  • Irresponsible off-highway vehicle use and high density of roads—The use of old roads causes soil loss and vegetation damage, affecting archeological sites and water sources, and separating wildlife from their habitat and invites uncontrolled and irresponsible off-highway vehicle use.
  • Unsustainable livestock grazing—One of the most pervasive threats to the region, domestic livestock grazing, leads to habitat degradation, shrub invasion, and soil erosion.

Protecting this region as a national monument would not only preserve the region’s ancient forests, protect corridors for migratory wildlife, and preserve thousands of archeological sites, it would also support clean drinking water, cultural heritage, and recreation.

Please ask President Obama to issue a declaration to protect the Grand Canyon's watershed as a national monument.
