SARATOGA – Beginning Monday, Aug. 26, several agencies, including the U.S. Forest Service’s Brush Creek/Hayden and Laramie Ranger districts, are planning to treat cheatgrass at multiple locations in and around the Medicine Bow National Forest through the aerial application of the herbicide imazapic.
The treatment area includes the Ryan Wildfire burn scar.
In addition to the Forest Service, the project is a collaboration between the Bureau of Land Management Rawlins Field Office, Carbon County Weed and Pest and the Wyoming Game and Fish Department.
This marks the second consecutive year of large-scale, multi-jurisdictional aerial cheatgrass treatment in southeast Wyoming. Approximately 3,300 acres were sprayed in 2018, with plans to treat approximately 10,800 acres this year.
Aerial spraying with a helicopter is scheduled to begin Monday. Actual treatment should take place over one to three days in each location, all within a window of several weeks, and weather-permitting, is anticipated to be completed by mid-September.
If necessary, temporary area and/or road closures due to the treatments will be signed by the respective land managers.
