WETLAND AND UPLAND INVENTORY <br />METHODOLOGY AND RESULTS <br />METHODS <br />The Methodology utilized for Inventory of upland and wetland natural communities in the <br />Roseville Natural Resource Management project is given in the following pages. <br />EVALUATION OF WETLAND SITES <br />Data from the National Wetland Inventory (NWI) map was used for preliminary determination <br />of wetland site locations in the study area. In addition, and MnDNR Forestry color infrared <br />aerial photographs were reviewed to locate wetland sites for field visitation. <br />These boundaries were further refined during the field visits as part of the inventory effort to <br />provide a more accurate location of the wetland boundaries. NOTE: These modified wetland <br />boundaries do not replace jurisdictional wetland delineations. The boundaries have been <br />provided for planning purposes only, to provide an estimate of wetland boundaries. <br />FIELD ASSESSMENT AND COMMUNITY TYPE DETERMINATION <br />The field assessment utilized the Minnesota Routine Assessment Method (MnRAM), Version <br />2.0. MnRAM was developed by the Minnesota Wetland Advisory Group as a field evaluation <br />tool to assess wetland functions on a qualitative basis. It considers, and assigns value to, many <br />functions associated with wetlands. As a result of discussions with City staff, the sections of <br />MnRAM listed below were used to evaluate wetland sites in the study area: <br />■ Floristic quality of each the plant communities within a wetland basin <br />■ Wildlife habitat value <br />■ Aesthetic / recreational /educational /cultural value <br />City of Roseville 59 <br />Parks Natural Resource Management <br />
