The Department of Agriculture Forest Service seeks noxious weed treatment by herbicide application on the Fort Pierre National Grasslands in Fort Pierre, South Dakota, with quotes due September 23, 2026 at 1:00 PM Mountain Time. The procurement is a total small business set-aside, firm-fixed-price commercial acquisition under FAR Part 12.

Two separate line items comprise the scope: War Creek Wildfire Noxious Weed Treatment (1172492) with a $30,000 budget targeting approximately 1,500 acres burned in July 2025, and FPNG Post-Prescribed Fire Weed Treatment (1172505) with a $60,000 budget across 2,604 gross acres with initial focus on a 1,192-acre pasture. Contractors must quote the number of actual treatment acres achievable within each dollar amount. Multiple awards may be made.

Performance runs September 23, 2026 through August 31, 2027, with flexibility for fall 2026 or spring 2027 treatment based on weather and growing conditions. Target species are Canada thistle, bull thistle, and musk thistle. Herbicide application must use GrazonNext HL at 24 ounces per acre via spot spray at 10 gallons per acre during rosette to flowering stage, with application prohibited when temperatures exceed 95°F or wind speeds exceed 15 mph. All treated areas must be mapped with GPS equipment using UTM Zone 13 North coordinates and submitted within two weeks of completion.

Contractors must hold valid South Dakota pesticide licenses, possess at least one year of experience treating noxious weeds in rangeland settings, demonstrate GPS capability, and establish a Quality Control Program before work begins. Performance standards require 90 percent kill of targeted species and less than 20 percent loss of non-target species. Evaluation weighs technical capability, price reasonableness per acre, relevant past performance within three years, and quality control plans.
