Newly plant- <br />ed aquatics are easily up- <br />rooted by wind and boat- <br />induced wave action. A <br />wavebreak provides a <br /> <br />Wavebreaks are placed out in the water beyond the area where aquatics will <br />be planted. The wavebreak device should be installed from the bottom of the <br />lake extending above the water, ideally above the maximum wave height. It <br />should be left in place for 1-2 growing seasons, and then removed. Wave breaks <br />are often removed for the winter to prevent damage from ice. Brush bundles, <br />coconut fiber rolls, plastic fencing and plywood are commonly used as wave- <br />breaks. Unless your property is located in a quiet bay, wave breaks are needed <br />for successful aquatic plantings. <br /> <br />Remember, a DNR permit may be required to install wave breaks. See "Planning <br />Worksheet 1: Permits." <br /> <br />A fence placed around new plantings protect plants from critter damage until <br />they become well established. Exclosures are used both in the water to keep <br />fish (carp) and water fowl from damaging aquatic plantings and in the wet tran- <br />sition/upland areas to protect from human, dog, goose, deer, rabbit and other <br />critter damage. <br /> <br />Fences can be temporary or permanent, but should be placed around a new <br />planting to channel foot traffic around planting or along designated paths. <br />
