Sierra Nevada

The Sierra Nevada is an icon of American wilderness and must-visit attraction for tourists worldwide. Tragically, its status has not made it immune to environmental degradation.

Yosemite and Sequoia National Parks and towering Mount Whitney are only a few of the natural wonders in the Sierra Nevada. Extending 400 miles north-to-south, including 12 million acres of federal public land, the Sierra Nevada mountain range’s size is matched only by its diversity, marked by regal granite spires, sapphire lakes and venerable forests.

Threats to the Sierra Nevada: Development, mining, logging, illegal roads and outdated land management threaten these stunning wildlands, as well as the recreation opportunities and economic benefits they provide to the region.

In the Sierra Nevada, The Wilderness Society is focused on winning protective designations for wildlands and improving federal forest restoration and management plans.

Assuring the Sierra Nevada’s future legacy

Wilderness designation

Sierra Nevada is known for Yosemite, Sequoia and other popular destinations. But many of its wild lands still need permanent protection. The Wilderness Society works towards preservation that would secure this American national treasure and outdoor legacy for generations.

Expanding public land holdings

We are working on federal funding to expand the Sierra’s public land holdings. These land purchases would help this region avoid development and would conserve the most critical wild lands.

Wise land planning and habitat restoration

To keep the Sierra Nevada forests wild, The Wilderness Society supports management plans that increase and restore habitat, protect potential wilderness and consider climate change.

Both wise future management and on-the-ground restoration projects ensure that the Sierra Nevada stays wild. The Wilderness Society’s California team is focused on both of these goals and is working with the Forest Service and local partners to accomplish this.

Forest planning

The Wilderness Society is working with the US Forest Service to improve their national forest management plans. Our initial focus will be on the Sierra, Inyo and Sequoia national forests. Our goals are to:

  • Augment wildlife habitats.
  • Protect potential wilderness.
  • Diminish severe wildfire threats.
  • Factor in climate change.

Restoring the land

A project to restore 37,000 acres in the Dinkey area of the Sierra National Forest will restore watersheds, improve habitat and help local communities with jobs. The Wilderness Society is working with the US Forest Service to improve their national forest management plans.

Improving Forests

The Wilderness Society improves the ecological health of Sierra Nevada forests when we identify illegal, eroding roads and trails – and convert them back to the wild.

Many illegal, user-created dirt roads and trails snake through these forests. As they disintegrate, they cause erosion and pollute rivers, which provide more than half of California’s water. We work to restore the health of these forests by identifying roads for future reclamation.

A network of eroding roads

More than 9,000 miles of unauthorized roads have been created by off-road drivers in California’s national forests. Many of these dirt routes and trails leave behind gouged-out meadows and eroded scars in the forest.

In the Sierra Nevada, these illegal or eroding roads pollute essential streams and rivers. This area is a critical watershed that gives California 60 percent of its water.

Restoring the forests' ecological health

To restore the health of Sierra Nevada’s forests, these disintegrating and illegal roads must first be identified. Eventually these roads can be turned back to nature, rebalancing the Sierra’s critical forest habitat.

Eliminating unnecessary roads can also recover the forest’s natural sounds, enjoyed by both wildlife and people.

Our partners

The Wilderness Society’s California office is working with coalition partners in the Sierra Nevada to win new wilderness protection, assist with forest planning and restoration and improve forest health by identifying illegal or eroding roads that can be reclaimed. We are making important gains:

  • To preserve additional public wild lands.
  • Improve forest management plans.
  • Begin restoration projects.
  • Improve the ecological health of forests by identifying roads that should be reclaimed by nature.

Experience the Sierra Nevada

The Sierra Nevada is a breathtaking mountain range that spans 400 miles of California north-to-south spine, including 12 million acres of federal public lands. Visitors enjoy an incredible array of experiences, from hiking near Lake Tahoe to climbing 14,494-foot Mount Whitney.

Don and Barbara's story

Whether northern or southern, rural or urban, Californians of many different backgrounds say wild lands give them beautiful scenery, clean water and a chance to recharge their souls. After moving to California in the 1960s, Don and Barbara become outdoor recreationists and then conservation activists working to protect to the Sierra Nevada and other areas that they love.

    New legislation introduced today in the House and the Senate would undermine state and federal planning efforts, nearly complete, to conserve the greater sage grouse and perpetuate uncertainty faced by all westerners, according to The Wilderness Society. The following statement can be attributed to Chase Huntley, senior government relations director for The Wilderness Society.

    Authorization for LWCF runs out on September 30 2015.

    Today, Earth Day, the Senate Energy and Natural Resources Committee will hold a hearing on “reauthorization and potential reforms” to LWCF. Funded primarily by offshore oil royalties—not taxpayer dollars—the program has had strong bipartisan support since its enactment in 1964. The Wilderness Society strongly supports several bills to reauthorize LWCF including S. 890, S. 338 and H.R. 1814, now pending in Congress.

    Proactive, cooperative conservation measures could be a model for protections across the West

    The following statement can be attributed to Nada Culver, senior director of agency policy and planning for The Wilderness Society, regarding the Department of Interior’s decision to not add the bi-state greater sage grouse population to the Endangered Species List.
