WI-TREMPEALEAU NWR - Basal Bark Treatment

The Fish and Wildlife Service seeks basal bark herbicide treatment of approximately 120 acres at Trempealeau National Wildlife Refuge in Wisconsin, with quotations due September 28, 2026. The procurement is a Total Small Business set-aside, restricted to women-owned small businesses.

Place of performance is Trempealeau National Wildlife Refuge, Wisconsin. The service period runs from the award date through July 30, 2027, with all chemical applications to be completed by April 30, 2027. Work consists of basal bark treatment on 105 acres of very low-density black locust and target woody species, and 15 acres of moderate-density treatment of black locust and target woody species less than 7 inches diameter at breast height. Only two approved herbicide mixtures are permitted: Garlon 4 Ultra with Milestone and Arsenal AC (Pesticide Use Proposal #R3-26-32579-006), or Polaris AC and Garlon 4 Ultra (Pesticide Use Proposal #R3-26-32579-012). The contractor must avoid treating bur oak and white oak; mistaken treatment of these species incurs a $1,000 deduction per tree. Work must occur Monday through Friday (except Federal Holidays) under specified environmental conditions: winds less than 10 mph at 20 feet, dry stems, and no rain, ice, or snow forecasted for the workday or 48 hours post-treatment.

The contract is firm-fixed-price, covering all labor, supervision, transportation, equipment, herbicides, personal protective equipment, and spill containment. Quoters must provide per-acre pricing for both density categories. The government will make award using a best-value tradeoff process evaluated on Technical Approach, Technical Experience, Past Performance, and Price. A minimum 95 percent treatment standard, verified through random sampling, is required for acceptance. Service Contract Act Wage Determination #2015-4929 (Revision 33) applies.
