Knotweed has infested the lower reaches of the Big and Little Quilcene Rivers. The Jefferson County Noxious Weed Control Board (JCNWCB), with assistance from the Hood Canal Coordination Council, and the Hood Canal Salmon Enhancment Group conducted assessment surveys to document with GPS coordinates the locations of Knotweed within the watershed and to determine the upstream extent of the infestation.

For a full description of work performed and phasing please see the narrative attached in the documents section of this webpage.

This project is a part of the larger Hood Canal Regional Knotweed Control Strategy. The goal of the Hood Canal Regional Knotweed Control Strategy is to outline a consensus strategy agreed to by all the partners working to control the spread of knotweed in the Hood Canal region. This strategy will enable us to inventory, treat and assess our progress towards eradication and control of Knotweed as efficiently and effectively as possible. This effort also serves to document the seriousness of the threat Knotweed poses to the ecological function of our aquatic ecosystems as well as the salmon that rely on those ecosystems.

Our objectives are to:

1. Move riparian areas toward a later seral stage by planting native conifers , shrub and hardwood species other than alder, where appropriate,
2. Expand the quantity, and improve the quality of riparian buffers,
3. Communicate with our partners effectively,
4. Establish common protocols and priorities for the required inventory, treatment, and assessment methodologies,
5. Create a program that will allow us to adaptively manage our efforts, and
6. Streamline funding and permitting for these efforts where appropriate.

Please see The Hood Canal Regional Knotweed Control Strategy in the documents section of this webpage for more information.
Knotweed projects conducted under the HCRKCS are coordinated with the Washington State Department of Agriculture (WSDA) Knotweed Eradication Program.

Note on metrics below- Plant removal miles counts actions taken in each year. Total riparian miles is total length treated, not including multiple years of treatment.
