Idaho County uses multi-pronged approach, computer-modeling to hold the line on noxious weeds

Cottonwood, ID

Idaho County is the largest county in the state of Idaho, extending from the Montana border to the east and the Oregon border, Hells Canyon, to the west. The county is truly massive -- it encompasses 5.4 million acres, or 8,438 square miles, including the Salmon River canyon, three wilderness areas, and private and public lands near Riggins, Grangeville and Cottonwood.

The county's enormous size -- as well as its steep, rugged mountains -- presents a big challenge for the Idaho County Weed Management crew. The county also grapples with large infestations of notoriously aggressive noxious weeds such as yellow starthistle, rush skeletonweed and others.

In partnership with state and federal agencies and the University of Idaho, Idaho County uses cuttingedge technology, computer modeling, biocontrol methods and direct control to hold the line on noxious weeds as best they can.
