The Stillaguamish Riparian Restoration Crew cultivated and installed native flora and enhanced existing as well as restored historical riparian buffers on 111 acres along 10.4 miles of the mainstem Stillaguamish, North Fork Stillaguamish River, and tributaries in the Squire, Portage, and Lower Pilchuck Creek sub-basins. Work sites were selected according to guidance provided in several documents, primarily the Stillaguamish Watershed Chinook Salmon Recovery Plan. Activities at a site included control of noxious weeds, planting native species, monitoring, and completing annual weed control to achieve a survival rate of 80% at 3 years. Planting plans at each site varied in species composition of native plants, planting density, and stock size to optimize plant survival.

All fish species in the Stillaguamish watershed will ultimately benefit, however primary emphasis was placed on sites where Chinook salmon spawn, migrate, and mature. Riparian buffers will provide shade, feed, refuge from floods, and large woody debris recruitment for Chinook and other salmonids. Project success came from utilizing an experienced, organized crew of dedicated inmates under professional supervision. The crew completed weed control and planting efforts crucial to effective site restoration. A vital feature of the existing project has been its direct contact with and appreciation by private landowners in the region.

Project Benefit    

The goal of the project is to restore native riparian vegetation along salmon bearing streams. The objective of the project is to restore natural streamside vegetation, improve stream temperature, reduce erosion, filtration, and recruit large woody debris.
