Situated on the spectacular Columbia Plateau, this large preserve is protecting open skies, dramatic geology and fascinating desert species in this region. Totaling more than 30,000 acres, this is one of the Nature Conservancy’s largest preserve in Washington, offering incredible geological scenery such as Ice Age flood-carved, steep-walled coulees, pothole lakes, haystack boulders, waterfalls and dunes as well as shrubs, grasses and wildflowers. This preserve provides habitat for resident species including the sage grouse, Columbia sharp-tailed grouse, pygmy rabbits and 14 out of 15 bat species reported in Washington.

This region is a great 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 agriculture or urban development. The Nature Conservancy has measures in place to ensure the long-term conservation of this habitat and its native species. Some of these measures include partnering with public and private landowners to advance the long-term conservation of 400,000 acres of functional shrub-steppe habitat, collaborating with agencies, farmers and ranchers to share knowledge in supporting viable populations of resident grouse and rabbits and working with partners, researchers and volunteers to develop a monitoring program for bat species and migrating birds.

This preserve is open year-round and offers 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 for birding.  Help keep this region safe and beautiful for everyone to enjoy, by leaving your canine companions at home, not removing plant or animal from the preserve and staying on the trail provided.

Listen and look for bats at Dutch Henry Falls during summer evenings.  Pacifiic treefrogs, Great Basin spadefoots, coyotes, great horned owls, poorwills, and canyon wrens are just a few of the other animals to listen for. Daytime visits may have western rattlesnake, gopher snake, and common garter snake sightings.
