DNR Hanover Bluff Hill Prairie Phase IV

The Illinois Department of Natural Resources (DNR) is seeking a qualified vendor to perform ecological restoration work at the Hanover Bluff Hill Prairie Nature Preserve in Jefferson County, specifically focusing on Phase IV of the project. The procurement involves cutting, herbicide treatment, and stacking of woody plants, predominantly invasive eastern redcedar, across approximately 0.75 acres of hill prairie terrain. Vendor requirements include possessing a valid Illinois Department of Agriculture Commercial Herbicide Applicators License and demonstrated experience working in natural areas with endangered species. Key deliverables include felling trees, cutting stumps within 1 inch of the ground, and applying specific herbicide treatments with 100% kill rates for conifers and 95% for broadleaf species. The project requires working on moderate to steep slopes near a cliff edge, mandating specialized safety equipment like climbing harnesses. The contract term runs from execution through March 31, 2027, with work completion by that date, though access is restricted between December 1 and March 1 due to potential inclement weather. The proposal submission deadline is October 1, 2025, with vendors required to submit comprehensive vendor experience documentation demonstrating previous work in native plant community restoration.

Vendor qualification criteria emphasize prior experience with natural habitat restoration, specifically requiring documentation of four reference projects involving Illinois Natural Areas Inventory sites, dedicated Nature Preserves, or registered Land and Water Reserves. Insurance requirements are stringent, including $1,000,000 in general commercial liability and $1,000,000 in auto liability coverage. While specific set-aside designations are not explicitly detailed in the documents, the comprehensive experience requirements suggest a competitive selection process prioritizing technical expertise over cost. The project appears to be fully funded by the State of Illinois, with the vendor responsible for all equipment, maintenance, and follow-up treatment expenses. Though exact contract value is not specified, the job specification document estimates approximately 332 hours of work, with final pricing to be determined prior to contract execution. Staff substitutions are permitted, provided the vendor's owner or primary field contact meets the established experience criteria. The procurement follows the State of Illinois Chief Procurement Office General Services Standard Terms and Conditions (Version 23.2), which establishes comprehensive contractual requirements for vendors.
