Automated Individualized Management Classification Using MNRAM Results A Visual User Manual Management Classification 7 A standard method for assessing MNRAM results endorsed by the MnRAM Workgroup Guides policy approaches using MNRAM wetland data Two preset levels for no fuss assessment Dial up levels allow flexibility for regional landscape or policy differences Management Classification Theory and Practice Classification provides a basis for developing wetland management recommendations It is the next step after gathering field data in MnRAM The objective is to achieve no net loss of wetland functions and values within the management area while providing flexibility for economic development that may require wetland impacts Impacts to wetlands include not only direct impacts such as filling draining and excavating but also indirect impacts from stormwater inputs changes to local surface and ground water hydrology and pollutant loading Each wetland can be classified according to a recommended level of wetland protection and acceptable hydrologic changes A wetland management classification system with management standards provides certainty to land use managers and developers Management Classification in Practice Each wetland can be classified according to a recommended level of wetland protection and acceptable hydrologic changes The protection level and hydrologic changes t
