Skagit Knotweed Program

Controlling the spread of invasive plants such as knotweed is incredibly important to having a healthy river ecosystem. Invasive plants can out-complete native vegetation and are not beneficial to native wildlife.
The Upper Skagit Knotweed Program has been working since 2001 to control the spread of knotweed in the upper Skagit watershed.
In 2018, the Skagit Fisheries Enhancement Group (SFEG) and partners in the CWMA surveyed knotweed along 83.6 miles of the Skagit River and major tributaries.
