Apishapa SWA Cheatgrass Treatment

The State of Colorado Department of Natural Resources, on behalf of Colorado Parks and Wildlife, is soliciting documented quotes for large-scale aerial herbicide treatments at the Apishapa State Wildlife Area. The project aims to treat approximately 2,000 acres of grassland and shrubland habitat to eliminate invasive cheatgrass and enhance habitat for bighorn sheep, mule deer, and pronghorn. The scope of work requires the application of a tank mixture consisting of indaziflam (Rejuvra) and imazapic herbicide with a non-ionic surfactant. Contractors must provide pricing for two scenarios: one where the state supplies the Rejuvra and one where the vendor supplies all materials. All work must be completed by June 30, 2027. The award will be based on the quote most advantageous to the state, considering price and other factors. Mandatory qualifications, including references and pattern testing, are evaluated on a pass/fail basis. Proposals must be submitted electronically via the Colorado Vendor Self Service portal or email by November 6, 2026, at 12:00 PM MST. Payment is issued as a lump sum upon project completion and approval by the Project Manager, following a net 45 payment policy. The contract is governed by Colorado Purchase Order Terms and Conditions and various state statutes, including preferences for resident bidders and Service Disabled Veteran Owned Small Businesses.
