Restoring Lands and Waters

Oregon Natural Desert Association sustains and enhances the health of Oregon’s high desert through stewardship and restoration.

While much of our wild terrain is beautiful and pristine in many ways, human actions over time have negatively impacted some areas. ONDA takes a holistic approach to conservation in Oregon’s high desert, pairing intensive on-the-ground stewardship with efforts to protect large landscapes. ONDA partners with land management agencies, private landowners, and tribal entities to undertake long-term restoration projects to improve land, waterways, wildlife and communities in Oregon’s high desert.

ONDA leads four main types of stewardship work:

  1. River and Stream Restoration
  2. Upland Restoration
  3. Wildlands Monitoring
  4. Trail Maintenance

Read on to learn about what’s involved with each type of work and to learn about the wild places where we’ve made a long-term commitment to restoration.

Found only in North America, where it is the most common wildcat, the bobcat takes its common name from its stubby, or “bobbed,” tail. The cats range in length from two to four feet and weigh 14 to 29 pounds. Bobcats mainly hunt rabbits and hares, but they will also eat rodents, birds, bats, and even adult deer.

Latin name: Lynx rufus fasciatus



What defines Oregon’s high desert?

What defines Oregon’s high desert?

Bounded by the Cascade Mountains to the west and the Blue Mountains to the north, Oregon’s high desert covers approximately 24,000 square miles. Annual rainfall in the high desert varies from 5 to 14 inches. The average elevation is 4,000 feet; at 9,733 feet, the summit of Steens Mountain is the highest point in Oregon’s high desert. The terrain of the high desert was mostly formed by a series of lava flows that occurred between 30 and 10 million years ago.

Stewardship Trips

ONDA works with hundreds of volunteers, students, seasonal field technicians, and nonprofit partners to get great work done. Our stewardship trips provide plenty of natural history education and opportunities for exploration, allowing volunteers to deeply connect with these landscapes. And, did we mention that these trips are lots of fun?

River and Stream Restoration

ONDA has always paid close attention to the health desert rivers and streams because these waterways are the lifeblood of Oregon’s high desert.  Add in the changing desert climate — less rain, warmer temperatures and stronger storms — and our riparian restoration work has taken on greater urgency.

From planting trees along stream banks to building low-profile structures that mimic beaver dams, each action is part of a thoughtful restoration approach that is guided by the best available science.

Our aim: Cool, clear, and enduring waters that support thriving populations of fish, wildlife and people

Upland Restoration

Across Oregon’s desert lands, barbed wire fences once used for livestock fragment the landscape. Many of these fences no longer serve a purpose and can harm wildlife. ONDA and partners have removed hundreds of miles of fence from the land. Where barriers are needed, we convert barbed to safer smooth wire. With each fence project we complete, ONDA supports wildlife and restores natural beauty to the land.

Our aim: Giving wildlife safe passage through the landscape


Featured projects

Wildlands Monitoring

ONDA’s wildlife survey volunteers help to monitor Greater Sage-Grouse leks or other sensitive species such as raptors and mule deer on trips that are conducted in cooperation with the U.S. Fish and Wildlife Service and the Oregon Department of Fish and Wildlife.

ONDA’s wilderness inventory volunteers collect critical information that helps ONDA document the conditions found in proposed wilderness areas. Participants collect GPS referenced photos to demonstrate that the area meets the requirements of wilderness: naturalness, opportunities for solitude and primitive recreation, and scenic and wildlife value.

Our aim: Providing high-quality data that wildlife agencies can use while managing sensitive species and  identifying wild lands that are suitable for wilderness designation

Featured projects

Trail Maintenance

ONDA’s trail maintenance work is focused on improving access to stretches of trail in the Fremont National Forest and on Steens Mountain that overlap with the Oregon Desert Trail. Working in partnership with the Forest Service and other local community groups, we are addressing critical safety concerns and promoting conservation in the region.

Our aim: Helping people connect deeply with the high desert landscape through muscle-powered recreation and gain a sense of responsibility for desert public lands
