Invasive species control

The Michigan Department of Natural Resources (DNR), Parks & Recreation Division, is seeking invasive species control services for eight state parks and recreation areas, including Algonac State Park, Belle Isle Park, Brighton Recreation Area, Fort Custer Recreation Area, Highland Recreation Area, Island Lake Recreation Area, Waterloo Recreation Area, and Watkins Lake State Park. The Request for Proposal (RFP) #250000002704 requires contractors to survey and treat specific invasive woody and herbaceous species using precise herbicide techniques, targeting plants like black locust, buckthorn, and bittersweet. Successful bidders must be pre-qualified vendors with demonstrated expertise in invasive species control and herbicide application, using specified chemicals such as Triclopyr, Aminopyralid, and Hexazinone. The project mandates comprehensive GPS mapping, detailed reporting, and strict decontamination protocols to minimize damage to native vegetation. Mandatory pre-bid meetings were scheduled between July 17-24, 2025, with the final bid due on August 1, 2025, at 9:30 A.M. EST. Treatment periods vary, with some zones requiring completion by September 30, 2025, others by March 1, 2026, and some potentially extended to September 15, 2026.

The contract will be awarded on a lump sum basis per treatment area, with pricing to reflect complete costs including equipment, labor, herbicides, and transportation. While no specific set-aside designations were mentioned, the RFP emphasizes the importance of technical expertise in plant identification, ecological restoration, and preservation of rare native plant communities. Contractors can bid on individual zones or groups of zones, with the state reserving the right to award the contract in full or in part. The bid remains valid for 30 days from the submission date, with potential for partial payments for significant work completed by specified dates. Though no specific budget range was explicitly stated, the comprehensive nature of the project suggests a substantial investment in invasive species management across multiple state parks. The contract requires detailed documentation of survey techniques, equipment, chemical usage, personnel qualifications, and prior experience, indicating a rigorous selection process that prioritizes technical capability and ecological sensitivity.
