By producing these large monoculture areas,the biological <br /> diversity is then essentially homogenizing to that of one habitat structure. Reed canary <br /> grass grows from seed, stem fragments, and rhizomes. Within one growing season,the <br /> rhizomes in the soil produce a dense mass which will out compete the native plants <br /> already rooted in the soil. Reed canary grass is a facultative wetland species meaning <br /> that it can grow wider a variety of hydrologic conditions. The grass tends to be found in <br /> moist or wet soils and can tolerate water conditions ranging from high water levels to <br /> drought like conditions. <br /> Reed canary grass is a persistent and tenacious Eurasian plant species that has been <br /> planted throughout the U.S since the 1800's. At the time,the grass was known for its <br /> large forage yields and erosion control abilities but as time went on other characteristics <br /> of the plant were recognized. Some of those characteristics include its prolific seed <br /> dispersal,robust vegetative growth, and dense network of underground rhizomes with <br /> thousands of dormant buds(Wisconsin Reed Canary Grass Management Working Group, <br /> 2009).Similar to buckthorn,the seed bank can last for up to 6 years meaning that follow <br /> up management will need to take place following the eradication of the invasive plant <br /> species. Reed canary grass is one of the first wetland plants to emerge in the spring and <br /> therefore is capable of shading out other native plants that emerge later. To eliminate <br /> reed canary grass,it is necessary to replant immediately with plant species that can out <br /> compete any residual plants or seeds, and retard erosion(Rhodes and Block,2002). <br /> The recommended way to eradicate the reed canary grass for this location is by using <br /> glyphosate. The best sequence for eradicating severe infestations of reed canary grass is <br /> to apply the glyphosate in the fall followed by a prescribed burn during the winter or <br /> early spring to bum off the dead thatch. Then spray again in the spring to kill the <br /> seedlings germinating from the seed-bank(Jacobson, 2006). The timing of these <br /> activities is extremely important for this method work effectively. Another control <br /> method is to mow the reed canary grass in late June and follow up with a late August or <br /> early September treatment with glyphosate by promoting active leaf growth. Also if a <br /> fall application of glyphosate is chosen,then no mowing should be conducted after July <br /> 15. It is important that these time periods are followed for a successful eradication of the <br /> reed canary grass. <br /> 16-19986 Franzel Addition-8CC North Arm Dr. <br /> Vegetation Management Plan <br />
