The purple loosestrife is currently being managed utilizing biological control methods that <br />include beetles by the Nature Interpretive Center. Purple loosestrife is causing other <br />species of the wetland such as swamp milkweed, wool grass, soft -stem bulrush, bottlebrush <br />sedge, spike rush, and manna grass to have lower densities and reduces the ecological integrity <br />of the basin. <br />The biological program should be continued by the Nature Interpretive Center. <br />A large compost pile exists on the west side of the wetland basin. Compost piles can contribute <br />a significant amount of nutrients to a wetland basin that can affect the wetland's plant <br />communities by promoting aggressive species that are not susceptible to nutrients. A review of <br />this site for water quality treatment should be completed to make sure appropriate treatment is <br />occurring prior to discharge to the wetland. <br />Community <br />Activity <br />Priority <br />Estimated Cost <br />Comments <br />CP -W 1 <br />Plant native <br />Low <br />$1000.00- <br />Enhance vegetative diversity and <br />vegetation along <br />$400.00 <br />aesthetics along the boardwalk <br />boardwalk <br />depending on <br />area of planting <br />CP -W1 <br />Control reed <br />Medium <br />$200.00 - <br />Herbicide treatment to set -back <br />canary grass <br />$800.00 <br />reed canary grass <br />CP -W 1 <br />Install <br />Medium <br />$500 -500 <br />This high profile area is a great <br />interpretive <br />depending on <br />place to install an interpretive sign <br />signage <br />size, quantity of <br />that explains purple loosestrife and <br />signage and <br />other invasive veg. threatening <br />material <br />wetlands. <br />CP -W 1 <br />Review water <br />High <br />$1,500.00 <br />Review of treatment of runoff <br />quality treatment <br />from compost site <br />of compost site <br />Community CP -W2 <br />Shallow Marsh <br />Qualitative Rank: Medium <br />Area: 2.5 acres <br />This is a narrow drainage channel that leads from a ditch and culvert under Dale Street to an <br />outlet pipe at a gravel access path.
