KS quivira NWR woody invasive species control

The U.S. Fish and Wildlife Service is soliciting a contractor to perform woody invasive species control services at Quivira National Wildlife Refuge in Kansas, targeting the mechanical and chemical treatment of invasive brush and tree species across 22,135 acres of wetland and prairie habitat. The primary objective is to reduce grassland fragmentation and support wildlife habitat by treating species such as salt cedar, Russian olive, red cedar, locust, Siberian elm, and plum species, with goals to reduce total shrub cover to 5-25% and completely remove targeted trees. Contractors must demonstrate comprehensive technical expertise in invasive species management, provide detailed treatment strategies for mechanical removal and chemical applications, and maintain extensive documentation throughout the project. The evaluation will prioritize technical capability as the most important factor, followed by past performance and price, with the government awarding a firm-fixed price contract to the most advantageous offer. Electronic quotations are due by August 11, 2025, at 5:00 PM EDT, with contract award anticipated for late summer 2025.

This opportunity is designated as a Total Small Business set-aside, with no incumbent contractors identified in the documentation. The contract is structured as a multi-year agreement spanning five years from September 2025 to August 2030, consisting of one base year and four consecutive option years, subject to funding availability and condition assessments. Work must be performed between April and September each year, with restrictions during June and July to protect nesting birds, and operations must accommodate whooping crane migration patterns. The contractor will be responsible for providing all labor, equipment, materials, and supervision necessary to complete the invasive species control across the refuge's priority and optional treatment areas. Performance will take place at Quivira National Wildlife Refuge in Kansas, with the government providing project guidance, maps, and site access while the contractor maintains responsibility for all operational aspects of the treatment program.
