about the natural area
from kingcounty.gov
"Steep valley walls and a broad valley floor combine to create rich mosaics of plant communities that characterize the natural area. Mixed forest and deciduous upland forests cover much of the valley wall, with several forested and scrub-shrub wetlands nestled in the benches. Gallery cottonwood forests, deciduous forests, meadows (old pasture/agricultural fields), and forested, scrub-shrub, and emergent wetlands are common on the valley bottom. Native plant installation and invasive plant control enhancement efforts have occurred along with streambed restoration projects focused on improving salmonid habitat. Several of these wetlands form the headwaters of short tributaries to the Green River. The lower reaches of the wall-based streams in this area are utilized for spawning by coho and chum, and rearing by chinook, coho, chum and winter steelhead. Cutthroat trout have also been reported."
