I feel that the ideas we discussed, namely building a boardwalk, installing a dock <br />and beach at the end of the point, dredging the channel to approximately half its current length, <br />and enhancing the vegetation of the nearshore area will contribute greatly to your enjoyment of <br />the property while maintaining and improving the habitat values. <br />Clearly the area with shallow water and cattails is overrun with purple loosestrife. Back at the <br />office, I made some phone calls and asked about the best ways to control purple loosestrife in <br />these conditions. The response clearly favored the use of beetles. Depending on the site, they <br />take from 3-8 years to impact the purple loosestrife population. The good news is that in 1997 <br />and in 1998, 3000 beetles were released on the southeastern part of Lake Owasso (see rnap). <br />Liter ibis month, the site •kviti he inspected to deierr~~i~1e whether or not the beetles nave become <br />established, how far they have spread and whether additional releases should be planned. Chuck <br />Fiedler, the Ramsey Co. Agricultural Inspector, is coordinating this effort. I suggest that you call <br />him at 651-482-5225 to find out more about this program and to inquire about a release on your <br />property. <br />Using herbicides at this stage won't impact the purple loosestrife population. While herbicides <br />may reduce the growth of some of the plants, the effect is superficial. The demise of the older <br />plants will create openings and enable seeds in the soil to germinate. A control permit is required <br />to treat the purple loosestrife with herbicides and the method of application is to spot treat each <br />plant. <br />There are no restrictions on cutting back the dried cattails and purple loosestrife plants. This <br />year's new growth will start from the roots. <br />The azea with "soft" ground along shore has a variety of native species, including sedges and <br />rushes, that are trying to grow. By controlling the invasive species (such as reed canary grass - <br />the grass with the transparent sheath that wraps around the stem at the base of the leaf) and <br />reducing the amount of mowing, a community of plants adapted to wet soils will develop. If you <br />wish, colorful species can be added such as blue vervain (Verbena hastata), mazsh milkweed <br />(Asclepias incarnata), blue flag iris (Iris versicolor), cardinal flower (Lobelia cardinalis), blue <br />lobelia (Lobelia siphilitica), ironweed (Vernonia fasciculata), turtlehead (Chelonia glabra) and <br />
