DNR Patterson Savanna LWR Woody & Invasive Species Control

The state of Illinois, specifically the Department of Natural Resources, is seeking a contractor to perform woody and invasive species control at Patterson Savanna Land and Water Reserve in Hardin County. The project focuses on ecological restoration by removing encroaching woody vegetation to maintain native prairie and savanna ecosystems. Specific work includes black locust control and cut stem treatment of invasive woody species such as blackjack oak, black cherry, and bush honeysuckle. Contractors must utilize precise treatment methods, including hack-and-squirt techniques for black locust using a 25% Garlon 4 and 3% Milestone herbicide mixture, and cut stem treatments with 50% Roundup solution. Work is scheduled between August 1 and October 15, 2025, with potential extension into 2026, and is subject to specific temperature restrictions (herbicide application below 80 degrees F). The solicitation was posted on October 23, 2024, with proposals due by November 4, 2024. Contractors must adhere to strict environmental control protocols, including leaving cut materials on the ground and avoiding brush pile construction.

The contract opportunity appears to be open to all qualified vendors, though prospective bidders must complete the State of Illinois Standard Certifications, which include compliance requirements across 33 different areas such as environmental protection, equal employment opportunity, and cybersecurity standards. Vendors must also meet insurance requirements, including $1M general liability and $1M auto liability coverage. While specific set-aside designations are not explicitly detailed, the standard terms suggest potential preferences for minority contractors. The contract is subject to standard state procurement terms, including record retention requirements, background check provisions, and termination clauses. Funding is contingent upon appropriation by the Illinois General Assembly, and contractors will be required to follow prevailing wage requirements if applicable. Though a precise contract value is not specified in the available documents, the technical specifications suggest this is a targeted ecological management project with specific scope and intervention requirements.
