It is rare to find this plant community <br />in southern Minnesota. Plant species included in this basin include steeplebush, purple <br />loosestrife, marsh fern, violet, sphagnum moss, bog birch, reed canary grass, dogwood, cattail, <br />leather leaf and blue flag iris. <br />Purple loosestrife has begun to become one of the dominant plants in portions of the wetland and <br />buckthorn is common along the edge. Currently Victoria Street is a rural section along this <br />portion of the basin with no curb and gravel shoulders. Untreated street drainage is likely <br />impacting the plant community of this basin. Water quality improvements could be pursued <br />adjacent to this road to improve drainage entering this basin. <br />Community <br />Activity <br />Priority <br />Estimated Cost <br />Comments <br />RW-W2 <br />Remove purple <br />High <br />$600.00 <br />Spot spray to remove purple <br />loosestrife <br />loosestrife to allow other species <br />and/or begin <br />native to bogs to establish. <br />beetle treatment <br />(Table continues) <br />City of Roseville 133 <br />Parks Natural Resource Management <br />
