164 <br /> I <br /> During our site visit, we noted the presence of 5 exotic, invasive plants: tree-of-heaven, <br /> multiflora rose, Japanese stilt grass, Chinese privet, and Japanese honeysuckle. We <br /> recommend controlling these species through the use of targeted, spot spray herbicide <br /> applications. Be sure to use the correct herbicide and application rates, When using <br /> herbicides, follow all label instructions. Near the stream and pond, we recommend using <br /> herbicides approved for aquatic use only, or using glyphosate with a surfactant with low <br /> toxicity to aquatic animals (e.g., Agri-dex Spray Adjuvant). Most likely, it will take <br /> several herbicide applications to keep these species under control. Information on <br /> controlling this species may be found at the following website: <br /> http://www.invasive,orgleastem/srs/. See the forestry leaflets Exotic, Non-native and <br /> Invasive Plants are a Problem,Multifl'ora Rose, Tree-of-Heaven,Japanese Stilt Grass, <br /> Chinese Privet, and Japanese Honeysuckle for more information. <br /> Water Quality <br /> Overall, water quality on your property is good and you have been maintaining your <br /> internal road system well. If you decide to install new roads or renovate existing roads, <br /> the following information could be useful to you. Some of these can also be used on <br /> walking trails (on a much smaller scale) if erosion becomes a problem. Below are some <br /> tips and diagrams. <br /> Water Bars <br /> Constructed with a bulldozer or tractor, a water bar is an earthen fill "mound-trench" built <br /> into the road or trail at a 15 to 30 degree down slope angle. It diverts rainwater off the <br /> pathway, thus minimizing erosion by preventing stormwater runoff from moving long <br /> distances along travel corridors. The water bar should be built such that the uphill end of <br /> the bar ties into any adjacent bank or cutwall to receive ditch flow. An energy absorber <br /> on the downslope outfall, such as riprap, brush, and treetops, will serve to slow and <br /> dissipate the water's movement; particularly if outflow can lead to gully erosion. When <br /> installed in series, the number used is dependent on the slope of the road or trail as <br /> follows: <br /> Grade of Road/'frail(Degrees) Spacing (feet) between Water Bars <br /> 5 135 <br /> 10 80 <br /> 15 60 <br /> 20 45 <br /> 30 35 <br /> ll <br />
