The Wagonhammer Aerial Herbicide Application project concluded on Friday, October 30th after treating 2,060 acres for cheatgrass and spotted knapweed over the course of three days.  Treatments are intended to decrease invasive annual grasses and noxious weeds to improve essential big game winter range and decrease hazardous fine fuels.  Herbicide drift monitoring was carried out during treatments and showed that there is essentially no drift beyond 50 feet of unit boundaries.  This is the expected result, although unit boundaries are drawn with wider buffers near water and private land.

This project is part of an ongoing joint effort between the North Zone Fuels and Botany, Invasive Species, and Pollinators Programs along with our partners at Idaho Fish & Game, the Mule Deer Foundation, and the Bureau of Land Management to manage cheatgrass in the Salmon River corridor at a landscape scale.  We would like to thank our volunteers for their help and the public for their cooperation in making this a big success!
