Knotweed Control

Knotweed is an extremely aggressive, non-native plant that was imported from Asia as a garden ornamental. Salmon ecologists are concerned about Knotweed because of its capability to smother native species and lower habitat biodiversity, water use and competition with native plants. Riparian planting with native plants stabilize  vulnerable stream banks, filter pollution, shade waterways and provide essential wildlife habitat. It provides a strong and diverse root system that protects the banks during high flow events, fixes Nitrogen and produces multiform soil conditions.  For more information on this invasion plant please read the Hood Canal Knotweed and Riparian Enhancement Project by our Project Manager, Mendy Harlow.

The Hood Canal Salmon Enhancement Group (HCSEG) has sponsored 4 years of  Knotweed Control and Riparian Enhancement projects.  See:  Knotweed Control & Riparian Enhancement – Years 1 – 3 and  Knotweed Control & Riparian Enhancement – Year 4
