Sweetwater County Weed & Pest

Sweetwater County Weed & Pest is a U.S. government entity registered in SAM.gov since July 2004 that provides integrated management of noxious weeds and pests to protect economic and ecological resources in Sweetwater County, Wyoming. The organization manages diverse rangeland ecosystems through unified support and leadership, with a core mission to protect ecosystems from invasive weeds that threaten native vegetation and reduce ecosystem productivity. The entity serves as a prime recipient of federal cooperative agreements focused on herbicide treatment programs and invasive species management across multiple landscape types and public lands.

Sweetwater County Weed & Pest has received four cooperative agreement grants demonstrating substantial expertise in noxious weed and invasive species control operations. The entity's work includes herbicide treatment of invasive species across riparian wetlands, upland habitats, and rangeland systems using multiple application methods including ATV/UTV sprayers, backpack sprayers, boom systems, and helicopter or fixed-wing aircraft applications as needed. Specific projects have targeted cheatgrass control through late-summer herbicide applications with comprehensive monitoring of cheatgrass density before and after treatment, bioassay of native species recovery, and mapping of treatment areas using spray logger technology. Federal funding has been provided by the Wyoming Region and DOI Fish and Wildlife Service Region 6, with cooperative partners including the Bureau of Land Management (BLM) and Wyoming Game and Fish Department. The grants span from award dates in October 2022 through September 2025, with ultimate completion dates extending through July 2030, reflecting ongoing, multi-year landscape-scale restoration and ecosystem management initiatives across Sweetwater County's public and protected lands.
