DESCRIPTION
The Hood Canal Summer Chum Riparian Restoration Project covered 3 stages of riparian habitat recovery: 1) maintenance of rivers where knotweed was at or near the controlled stage; 2) treatment of rivers where knotweed was not at the controlled stage; 3) planting and maintenance of native riparian vegetation on parcels where knotweed patches were deemed to be controlled to level that would allow the re-introduction of native vegetation and maintenance of those plantings to ensure the survivability of native plantings.
At the inception of this project HCSEG focused on assessing and controlling knotweed along seven river systems in the Hood Canal watershed: Union River, Tahuya River, Dewatto River, Big Anderson Creek, Little Quilcene River, Big Quilcene River, and Dosewallips River. An additional system, Big Beef Creek in Kitsap County, was added to the project in late 2015 after knotweed was found in the lower reach adjacent to a restoration site. Big Beef Creek was surveyed, in coordination with Kitsap County Noxious Weed Control Board, in fall of 2015. Outreach to gain landowner support for Big Beef Creek began in early 2016.
Knotweed treatment season started in late July for each year of the project and extended into late September, depending on plant growth and weather conditions. HCSEG utilized aquatic herbicide applications that adhered to all regulatory requirements. During this project HCSEG conferred with all three County Weed Coordinators and other organizations controlling noxious weeds in the Hood Canal watershed, for technical guidance to ensure that the appropriate herbicides and treatment methods were utilized, and areas weren’t unintentionally double treated. This important safeguard prevents duplicate work and ensures that BMP’s are followed.
Planting season for the project occurred during early January into late March, dependent on weather conditions. Planting maintenance occurred in late spring through early summer, dependent on crew availability. HCSEG utilized a Washington Conservation Corps crew to assist in the treatment of knotweed, plantings, and all plant maintenance activities that were undertaken. The remaining time throughout the year was spent planning upcoming field work, updating landowner consent, outreach events promoting noxious weed education, landowner outreach to new owners to secure participation, yearly reporting, renewal of required permits, development of planting plans and plant purchases. At the time of completion the project has roughly 300 participating landowners along 8 river systems in the Hood Canal watershed.
