DNR Hanover Bluff Hill Prairie Phase IV

The Illinois Department of Natural Resources (DNR) is seeking a contractor for the Hanover Bluff Hill Prairie Phase IV project, a specialized ecological restoration and invasive species management initiative. The primary scope involves clearing approximately 0.75 acres of hill prairie, with a specific focus on removing invasive eastern redcedar trees and brush through precise cutting and herbicide treatment techniques. Vendors must possess a valid Illinois Department of Agriculture Commercial Herbicide Applicators License and demonstrate at least two years of professional experience in herbicide application within natural areas, with 50% of on-site staff meeting this qualification. The contract requires detailed daily work logs, weekly email updates, and stringent performance standards, including a 100% kill rate for conifers and 95% for broadleaf species. Work will be conducted along hill prairie/cliff edges with specialized safety requirements, including climbing harnesses, and is limited to seasonal access between December 1 and March 1. The project has a contract term ending on March 31, 2027, with a proposal submission deadline of October 13, 2025. Vendors must submit comprehensive documentation demonstrating experience with native plant communities, endangered species habitats, and natural area management.

While no specific set-aside designations are explicitly mentioned, vendors must meet rigorous qualification standards and provide extensive documentation of previous project experience. Insurance requirements are substantial, including $1,000,000 per occurrence for general commercial liability and auto liability, with the State of Illinois to be named as an additional insured. The contract allows for staff substitutions provided that the vendor's owner or primary field contact meets specified experience requirements. Vendors must complete a Vendor Experience Documentation form detailing up to four reference projects, including project specifics such as location, native plant community type, land use, acreage, and work completed. Though a specific budget range is not provided, the detailed technical specifications and environmental management requirements suggest a specialized contract requiring significant technical expertise and ecological restoration capabilities. The project appears to be part of a broader conservation effort focused on preserving and restoring critical hill prairie ecosystems in Illinois.
