Improvements completed on the Chehalis River Surge Plain Natural Area Preserve walking trail in Grays Harbor County
Chehalis River Surge Plain Natural Area Preserve
Chehalis River Surge Plain NAP is located in Grays Harbor County. The preserve supports a large wetland area that spreads out at the lower end of the Chehalis River just upstream from where it empties into Gray's Harbor. Sitka spruce and western red cedar thrive in the wet soils, where fresh and salt water mingle on this 2,643 acre site. This preserve contains the largest and best quality tidal surge plain wetland in the state. The site protects sloughs that wind through the site, providing important shelter for young salmon and other fish.
Natural Area Preserves
DNR is steward of about 31,000 acres of NAPs in 51 preserves throughout the state. NAPs protect outstanding features including native forests and grasslands, bogs, and sagebrush communities. Habitats for rare plant and animal species, such as basalt daisy, the Puget blue butterfly and Oregon spotted frog are also protected. Preserves have been established in most areas of the state. They range in size from about 5 acres to 3,600 acres. Natural Area Preserves are acquired through gift or purchase from willing sellers.
