The U.S. Fish and Wildlife Service's Partners for Fish and Wildlife Program is soliciting noxious weed control services through pesticide application at Antelope Flats within the Klamath Basin National Wildlife Refuge Complex in California. The contractor will be required to perform spot treatments of invasive species including Bull Thistle, Yellow Starthistle, meadow foxtail, and other "A" or "B" listed noxious weeds within a 298-acre search area owned by Fort Baker Ranch LLC. Key requirements include possessing appropriate Oregon pesticide application licenses, utilizing specific herbicide applications with aminopyralid (Milestone Specialty) and surfactant using ATV/UTV mounted spray equipment, and providing GPS tracking data compatible with ArcGIS. The procurement will be awarded based on lowest price technically acceptable criteria, with technical acceptance requiring valid state/federal pesticide certifications and demonstrated qualifications through a two-page technical proposal. The solicitation deadline has been extended to June 24, 2025 at 1200 Eastern Daylight Time, with the contract period of performance running from June 9, 2025 to July 1, 2027.

This opportunity is designated as a Total Small Business Set-Aside under NAICS code 115310 (Support Activities for Forestry) with a size standard of $11.5 million. The firm-fixed price contract includes a base year covering three spot treatments from June through November 2025, with two optional one-year periods for treatments in 2026 and 2027. The work involves conducting east-to-west transects approximately 10 meters wide across two large open meadows, with treatments timed to maximize herbicide effectiveness during target weeds' physiological development phases. Performance will take place at Antelope Flats in Klamath County, Oregon, despite the solicitation indicating California in some references. Contractors must coordinate with FWS prior to each treatment application and submit progress reports, with all work conducted under the Federal Noxious Weed Act's integrated management framework to minimize environmental impact while controlling invasive plant species.
