Tlie <br />Minnesoiw outine Assessment Method (MinRAM) was used to evaluate Lhe floral diversity and inlegnty <br />of the wetland. <br />The wetland community contained predominately american elm with a groundlayer dominated by hep <br />sedge and bristle pinkweed. Reed canary grass and cattail comprise less then iO percent of the wetland <br />and aie is»)la‘.ed m one end. MinRAM defines a High Quality Hardwoi.xi Swamp as haviny, Lho following <br />characteristics: <br />Slancii undisturbed or minimally disturbed by anificial drainage, grayjng, logging, impoundment, jilling, <br />etc. Seedtnigs and/or saplings of native tree species evident Indicating i •’generat ’on. Groundlayer <br />composed of native grasses, sedges, ferns and/or forbs. Box elder, buckthorn, and/or reed canary grass, if <br />present, each have less than 10 percent cover. <br />Thi.s wetland meets MinRAM High Quality Hardwood Swamp standards. Excavation of this wetland <br />would greatly degrade the system which exists. High Quality Hardw ood Swartips arc not prevalent in <br />much of the metro area and usually are preserved when p*ossible. <br />Tlie upland area between the wetland and the road contains stands of buckthorn. Buckthcni is an exotic, <br />unctee’.rabic licc. si:, aggretii* e aiid cAcn cut eon.potcs fuitivc wcir.dla.-.d spcc'.ec, which have li'ghei <br />va'ues for wildlife. If they still want a pond, I would suggest placement of a small pond in the adjacent <br />upland area, between the wetland and the road A pond at this location will eliminate the buckihom. Site <br />ccnsiiaints will likely limit them to a shallow pond with emergent wetland plants, such as caltall, across tlie <br />entire surtacc area. If a pond was constructed in the upland aiea surrounding the wetland, erosion control <br />should be required, to protect the Hardwood Swamp. <br />Please contact me if you have any questions or need fuilher assistance. <br />Sincerely, <br />BONESTROOJROSENE.'T^NDERLIK & ASSOCIATES.
