DESCRIPTION
The South Fork of the Stillaguamish River is on the 303(d) list for the fecal coliform, temperature, pH and dissolved oxygen. Degraded riparian conditions are known to contribute to poor water quality, and existing riparian conditions on this section of stream are known to be degraded. A 2006 Land Cover analysis by Snohomish County SWM shows only 12% evergreen forest, 20% deciduous, and 30% shrub/small trees within 300 feet of the Lower South Fork Stillaguamish subbasin with over 36% without tree or shrub buffer of any kind. This project implemented a watershed scale approach to addressing these degraded conditions, specifically temperature, by working with public and private landowners to control invasive plants, plant large stock (4-8 foot) native conifers and install livestock exclusion fencing in degraded riparian habitat within 100 feet of the South Fork. The long-term goal is to decrease in-stream temperatures through accelerating establishment of native conifers near the stream to provide year-around shading and bank stabilization.
