This session will demonstrate Clay SWCDs ArcView extension for wetland management. This is an automated mapping application to assist resource managers access and print information for possible wetland impact and replacement sites. Clay County, funded by a challenge grant through the Minnesota Board of Water and Soil Resources (BWSR) and Legislative Commission on Minnesota Resources (LCMR), has developed a wetland model to assist in local wetland planning. An interagency technical panel was assembled to develop criteria for evaluating wetland functions based on their area of expertise. Wetland Functions were determined by physical or geophysical characteristics and rated as low, medium or high. Seven characteristics were considered for prioritizing wetland functions; uniqueness, fisheries habitat, wildlife habitat, rare and endangered species, surface water quality, groundwater sensitivity and flood attenuation. The user can select a wetland and print out a datasheet with map showing location along with landowner information, wetland attributes, watershed information and wetland function rating. The user can also query for locations of possible replacement sites and print out a datasheet. There is an option to choose sites based on functions or total scores in the same or another watershed. Possible drained basin sites can then be systematically reviewed to determine the best site for mitigation.
