Mitigation banks are a tool created to mitigate and compensate for negative impacts on the environment resulting from man made activities, especially damage caused to endangered wildlife, plants, and wetland ecosystems. The main objective of creating the system of mitigation banks is to achieve environmental equilibrium, meaning “No Net Loss” to all environmental functions. This means damage to one area is compensated for in another area of like-kind through restoration. There is great controversy surrounding this claim. There is a system of debits and credits to ensure ecological loss from development is preceded by restoration of a similar ecology and function. Wetland mitigation banks are the focus for the purpose of research. Background and benefits will be given first, followed by threats, issues, solutions and a personal experience with mitigation banks.
