The Wisconsin and Minnesota Wetland Rapid Assessment Methods (RAM) are currently used to evaluate wetland function and inform some regulatory and mitigation decisions. Supported by US Environmental Protection Agency wetland development grant funding, state agencies in Minnesota and Wisconsin are working jointly to update their RAM with a quantitative tool that evaluates several wetland functions, including water quality, hydrology, ecology, and human use values. Presenters will discuss the strategy for developing the new tool and show current tool functions, data sources, and plans for field testing and public input.
