The Wenatchee River Ranger District plans to hand pull, spray and replant about 300 acres of weed-infested lands on the Okanogan-Wenatchee National Forest in the mid to upper Wenatchee Valley this summer.
Areas scheduled for treatment include Hay Canyon, Nahaham Canyon, Mission Creek, Van Creek, Derby Canyon, Eagle Creek, Camas Creek, Scotty Creek, Shaser Creek, Natapoc Mountain and other selected roadsides and trailheads.
The chemical spraying will include two kinds of biodegradable herbicides that will be spot applied to only the weeds, a news release from the agency said. Sites will be posted so people will know if they are in an area treated by an herbicide, which will be colored with blue or yellow dye.
Weeds to be treated include diffuse and spotted knapweed, sulfur cinquefoil, dalmation toadflax, bull and Canada thistle, spotted cat’s ear, common tansy, St. Johnswort, knotweed and white top.
A Forest Service crew will also hand-pull some of the weeded areas, and areas will be replanted with competitive grass seed mix after they are pulled or sprayed, the release said.
