Invasive species control

The Michigan Department of Natural Resources (DNR), Parks & Recreation Division is seeking a comprehensive invasive species control contract for eight state parks and recreation areas, including Algonac, Belle Isle, Brighton, Fort Custer, Highland, Island Lake, Waterloo, and Watkins Lake. The Request for Proposal (RFP 250000002704) solicits qualified contractors to perform systematic removal of invasive woody and herbaceous species using specific herbicide treatments. Bidders must be certified commercial pesticide applicators with pre-qualification in invasive species control, capable of using approved chemicals like Triclopyr, Milestone, and Velpar L with precision to minimize damage to native vegetation. The project requires detailed documentation of treatment techniques, personnel qualifications, project management approach, and equipment specifications. The proposal is due on August 1, 2025, at 9:30 A.M. EST, with mandatory pre-bid meetings scheduled between July 17-24, 2025. Contractors must provide comprehensive pricing breakdowns including labor rates, equipment costs, travel expenses, and chemical supplies, with the bid remaining valid for 30 days from submission. The contract completion deadline is set for September 30, 2025, with potential flexibility extending to September 15, 2026.

The RFP does not explicitly outline specific set-aside designations for disadvantaged enterprises. Bidders must demonstrate comprehensive capabilities to treat multiple park zones, with the state reserving the right to award the contract in full or in part based on individual line item capacities. Contractors will need to specify their preferred treatment seasons and the minimum and maximum number of line items they can effectively manage. While specific budget ranges are not detailed, the contract is structured as a fixed-price procurement with pricing determined by individual treatment zones and potential volume discounts. The successful vendor must exhibit extensive experience in ecological preservation, including thorough equipment decontamination between sites and careful navigation of treatment zones, particularly in areas with rare plant species and sensitive natural communities. Bidders will be evaluated on their technical expertise, environmental sensitivity, cost-efficiency, and ability to minimize incidental damage to native ecosystems during invasive species removal.
