There are few remaining examples of the shrub-steppe ecosystems that once flourished in Eastern Washington.  This 293-acre site contains some of the best examples of these ecosystems, such as the rare antelope bitterbrush/Idaho fescue community.  Spring wildflowers on Davis Canyon's sloping hillsides include blanket-flower, desert yellow-daisy, lupines, mariposa lilies, death camas, yellow bells, shooting star, prairie- smoke, and larkspur.  This site was designated a National Natural Landmark in 1986, in recognition of its nation-wide significance to natural area protection.  (Okanogan County)
