About this opportunity
The Fish and Wildlife Service seeks hazardous fuels reduction and habitat enhancement services at Klamath Marsh National Wildlife Refuge in Oregon, with proposals due September 1, 2026. This is a Women-Owned Small Business (WOSB) set-aside; however, Amendment 0004 (issued August 28) converted the procurement to full and open competition, requiring offerors to acknowledge receipt of this amendment prior to the original deadline or face rejection.
Place of performance is Klamath Marsh National Wildlife Refuge, Klamath County, Oregon. The contract period runs from August 28, 2026 through January 1, 2028. The NAICS code is 238910, Site Preparation Contractors, with a $19 million size standard. The firm fixed-price not-to-exceed award value is $451,179.
Work involves mechanical and manual treatment of designated units within the refuge, including small tree and brush thinning, pruning, and piling on suitable ground. Contractors must thin conifers less than 12 inches diameter breast height (except aspen) to create 15-foot crown-to-crown spacing, remove brush and dense fuel loading, and limb remaining trees to 6 feet height. Pricing shall be submitted on a per-acre basis. Sensitive areas requiring exclusively manual cutting and hand piling are expected to comprise less than 10% of total acres; habitat-retention clumps designated for approximately 15% of the project are included in measured and accepted acreage for payment. Mechanical equipment is excluded within 100 feet of surface water, though post-award unit delineation may reduce this exclusion during dry or frozen ground conditions based on annual water-level fluctuations.
Contractors must submit a statement demonstrating understanding of the work and site conditions and are strongly encouraged to visit the site prior to quoting; site visits can be arranged by contacting Riley at (530) 708-7723. Evaluation emphasizes technical capability and past performance significantly more than price, with award to the responsible offeror submitting the lowest evaluated price meeting acceptable technical standards.
