ENTIAT SLOPES NATURAL AREA PRESERVE

Features Protected: Thompson’s clover and longsepal globemallow
Ecoregion:  East Cascades (Chelan County)

Site Description
This 1,920-acre site and its surrounding landscape are characterized by steep, rugged terrain and narrow canyons that terminate at the edge of the Columbia River. The preserve contains one of the largest known populations of Thompson's clover, a plant that is state-listed as “threatened,” and a population of longsepal globemallow, a state-listed “sensitive” plant. The preserve, which also contains grasslands and scattered ponderosa pine and Douglas-fir, is susceptible to—and has evolved with—frequent natural fires. Longsepal globemallow, an apparently fire-dependent species, drastically increased in numbers following the most recent fire in 1988.
