The goal of this project is to improve salmon habitat for all freshwater stages of Nisqually River Chinook by dramatically reducing the infestation of Japanese knotweed in the Upper Nisqually River and its tributaries. This is a continuation of previous knotweed eradication projects in the same focus area. We will continue surveys of the Nisqually River and its tributaries verifying and updating data previously collected, and continue to assess knotweed presence in areas not previously assessed. Maps of the project area will be updated accordingly. Outreach to landowners will be continued to achieve increased survey and treatment footprints, and to educate and mobilize landowners to understand the importance of, and to assist in, knotweed eradication in their riparian community. Efforts to eradicate all knotweed found in the project area will be continued using a strategic top-down approach informed by our survey findings. Our ultimate aim is to reduce knotweed in the basin to a maintenance level, where SRFB funding will no longer be necessary for knotweed control. Aggressive eradication will continue until 2020, when knotweed is expected to have been successfully controlled. Anticipated project deliverables include 200 acres of riparian land, and 6 river miles, treated for knotweed. Pierce Conservation District will provide matching funds for the proposal herein.
