Chopaka Mountain Natural Area Preserve

subalpine forests and shrub-steppe peaks
This high-mountain preserve encompasses 2,764 acres at elevations ranging from 4,400 to 7,882 feet in the Eastern Cascades. The site protects 11 state-listed plant species, including gentians, cinquefoils, moonwort, willow, and others. Mountain goats range the rocky ridgetops on the preserve's highest peaks (Chopaka also supported the last native herd of bighorn sheep in Washington, which was hunted out in the 1920s). The preserve also includes fine examples of low-growing alpine turf communities, subalpine forests and shrub-steppe, creeks, ponds and meadows abundant with mountain wildflowers.  
Features Protected: Three state-threatened plants, eight state-sensitive plants, alpine turf plant communities, subalpine forest plant communities, and a subalpine pond with associated riparian system.
Ecoregion:  Okanogan (Okanogan County)
