Project Goal:

Restore salmonid stream channel and floodplain rearing habitat on a highly degraded abandoned Mill Site through a multi-phase design and implementation program. Establish the Save the Redwoods League’s property as a key focal location for visitors to Redwood National and State Parks (RNSP) to experience the restored lower Prairie Creek, critical habitat for coho salmon and steelhead, and the magnificence of old-growth redwoods through a trail network and Gateway visitor center at the heart of RNSP.

Project Description

Prairie Creek runs through Redwood National and State Parks, and is the most pristine redwood watershed remaining in California; and is critical habitat for threatened Chinook salmon, coho salmon, and steelhead. The coho population in Redwood Creek is one of the largest within its range, and almost all of the coho derive from Prairie Creek. At the junction with Redwood Creek lies Save the Redwoods League’s Orick Mill Site property, a site whose importance for salmonids is highlighted by the poor conditions downstream in the Redwood Creek estuary.  Working closely with the League, CalTrout is leading a team to design and implement restoration of Prairie Creek and tributaries including floodplain enhancement, wetland and native vegetaion restoration. The restoration of Prairie Creek is a part of the League and National Park's visionary development of a new Redwood National and State Park Visitor Center. At this World Heritage Site, restoration of critical floodplain habitat for threatened Chinook salmon, coho salmon, and steelhead will be showcased for visitors from around the world.
