Three Forks Natural Area

Snoqualmie, WA 98065 (King County)
The 418-acre Three Forks Natural Area is located in rural eastern King County at the confluence of the three forks of the Snoqualmie River, the largest river system in King County. With sweeping views of Mount Si and Rattlesnake Mountain, the Three Forks Natural Area includes over five miles of riverfront with juvenile trout habitat, and serves as a sanctuary and corridor for a broad range of wildlife including black bear, elk, cougar, eagle, deer, and river otter. Meadowbrook slough, one of the most notable Class I wetlands in Three Forks Natural Area, has suffered degradation through the introduction of invasive plants such as Himalayan blackberry and Japanese knotweed.  These plants do not provide needed shelter for wildlife and fish and their competition jeopardizes the health of native vegetation.  Last year volunteers removed huge areas of blackberry and planted additional native trees and shrubs in its stead.  We are returning this year to continue to remove encroaching blackberry to ensure the survival of the native trees and shrubs.
