- This 37,842-acre mountainous conservation area protects outstanding examples of native plant communities and other ecological features, such as subalpine meadows, wetlands, and lakes. Six plant species rare to Washington state occur within these habitats. The site is also large enough to provide important habitat for threatened and endangered wide-ranging wildlife such as Pacific fisher, grizzly bear, and gray wolf. The NRCA protects the middle and high elevations around the Spada Lake basin, which captures warm moist air as it moves inland from Puget Sound and the Pacific Ocean to create one of the wettest areas in the North Cascade Mountains. High precipitation and cool temperatures cause subalpine plant communities to occur at unusually low elevations in this region.
