The spread of noxious weeds in Gilliam County results in substantial economic and environmental impact. The priority weeds are a growing problem in this area and are the single greatest threat to native rangeland biodiversity. These weeds are inhibiting the watershed’s ability to capture, store, and safely release precipitation. Last year we treated an estimated 860 acres on Thirtymile Creek as well as another 615 acres on Hay Creek for Spotted Knapweed, Dalmatian Toadflax, Diffuse Knapweed, and Russian Knapweed at infestations high enough to adversely affect wildlife populations, endangered species, watershed functions, and human activity.
Spreading herbicides by helicopter helps control the spread of noxious weeds in Gilliam County.
