Situated on the spectacular Columbia Plateau, these large preserves are protecting open skies, dramatic geology and fascinating desert species in this region. Totaling more than 30,000 acres, these are some of the Nature Conservancy’s largest preserves in Washington, offering incredible geological scenery such as Ice Age floods-carved coulees, pothole lakes, haystack boulders, waterfalls and dunes. These preserves provide habitat for resident species in need of protection, including the sage grouse, Columbia sharp-tailed grouse, pygmy rabbit, Washington ground squirrel and 14 of the 15 bat species found in Washington.

This region is an important example of Washington’s shrub-steppe, which historically comprised almost a third of the state’s entire land mass. Currently, more than two-thirds of this habitat has been lost to development. Through management of these preserves, The Nature Conservancy is working to ensure the long-term conservation of shrub-steppe habitat and its native species. Our efforts include partnering with public and private landowners to advance the long-term conservation of functional shrub-steppe habitat; collaborating with agencies, farmers and ranchers to support viable populations of resident grouse and pygmy rabbit; and working with partners, researchers and volunteers to monitor plants and wildlife.

These preserves are open year-round and offer a variety of beautiful sites to explore! View wildflowers on the Monument Hill Trail during spring, listen for bats at Dutch Henry Falls during summer evenings and visit McCartney Creek Meadow to observe its birds. Help keep this region safe for wildlife by leaving your canine companions at home, not removing plants or animals from the preserves and staying established trails.
