Project Highlights:

    Meadow knapweed joint WMA containment

• Meadow knapweed can be found both in Humboldt and Del Norte counties. In Humboldt county it is present in the Weitchpec area and in Del Norte County this weed can be found in and around Crescent City, along Forest Service routes, and around five acres of a wilderness trailhead. This project was jointly developed when Humboldt and Del Norte counties were a joint WMA and exemplifies a bi-county, early detection and treatment approach to managing an A-rated pest, meadow knapweed. The spread of meadow knapweed is being addressed at an early stage to protect habitats and high-value sites such as pasture land, oak woodland communities, riparian areas, river bars, a botanic area, designated wilderness, and designated Wild & Scenic Rivers. This project deliberately engages multiple stakeholders in the management of meadow knapweed on all fronts. The project integrates manual hand pulling and grubbing, weed cloth, weed whacking, Waipuna hot foam treatment, revegetation, and herbicide use. Project partners include U.S. Forest Service, Mid-Klamath Watershed Council, CalTrans, California Department of Food and Agriculture, Del Norte County Agricultural Commission, Yurok Tribe, and Bureau of Land Management.
