Description

The Wisconsin Wetland Conservation Trust (WWCT) is seeking a contractor to provide Long-Term Management (LTM) services at Wisconsin In-Lieu Fee (ILF) Wetland Mitigation sites. The goal of this LTM work is to maintain and improve ILF mitigation sites that have met final performance standards and have been released from performance monitoring. The work will primarily center on annual invasive species control and occasional prescribed burning. The contract is for one year with four one-year renewal options for a total possible contract of five years. • The WWCT has restored 14 sites totaling 850 acres. • ILF mitigation sites must meet vegetative performance standards, typically for five years. • Typical LTM tasks will consist of invasive species control through herbicide treatments and mowing, prescribed burning, and potentially occasional reseeding. • A non-wasting endowment with the Natural Resources Foundation of Wisconsin will provide funding for LTM activities.

Budget estimate

$700,000 – $3,500,000

The budget for this contract can be estimated based on the scope of work and the fact that it is a five-year contract with a non-wasting endowment providing funding for LTM activities. The cost of invasive species control, prescribed burning, and occasional reseeding for 14 sites totaling 850 acres can vary widely depending on factors such as the type and density of invasive species, the frequency of prescribed burning, and the cost of herbicides and labor. However, as a rough estimate, the annual cost of LTM services for a single site could range from $10,000 to $50,000, depending on the specific requirements of the site. For 14 sites, the total annual cost could range from $140,000 to $700,000. Over a five-year period, the total budget could range from $700,000 to $3,500,000.
