PRIME VEGETATION MANAGEMENT <br />PO Box 1440 <br />PYN Berthoud, CO 80513 <br />970-2221543 <br />February 173, 2009 <br />1 aFarge North America <br />Attn: David Jordan <br />10170 Church Ranch Way <br />Suite 200 <br />Westminster, CO 80021 <br />As requested we have prepared a brief outline for tamarisk and noxious weed control and monitoring at the <br />West Riverbend property. The topics we will summarize are present noxious weed species, potential noxious <br />weed species, control recommendations and monitoring. <br />During our site visit on February 18, 2009, the primary noxious weed species identified was tamarisk. This <br />perennial shrub or small tree is located around the bodies of water on site. We recommend a basal or foli,ar <br />herbicide application for lasting control of these shrubs. An accurate herbicide application will minimize <br />damage to the surrounding desirable plants. An aquatic label herbicide should be used immediately adjacent to <br />the water. The dead tamarisk may be left in place to stabilize the pond slopes. Three applications per ye?ur are <br />recommended to control the tamarisk infestation- The majority of the tamarisk will be eliminated in the first <br />year; however an ongoing program will be necessary to control new plants as well as those that survive the <br />previous applications- <br />The river corridor is very diverse in its plant life. Many of the plants found are desirable, but it is not unusual to <br />find noxious weed species. Noxious weeds in the surrounding area include Leafy Spurge, White Top, Scotch <br />Thistle, Musk Thistle, Canada Thistle, and Diffuse Knapweed. These additional noxious weed species wNe not <br />identified during our initial visit. Ongoing monitoring will prevent an infestation of these species. <br />Monitoring of the property can be efficiently accomplished at the same time that the tamarisk trees are being <br />controlled. firing the th_me tamarisk applications per year other noxious weed species will be noted. If <br />additional noxious weeds are identified they may be suppressed by mechanical mowing and ul mately <br />eliminated by an ongoing herbicide program. <br />Please contact Josh Wood at 970-2224543 with any questions, suggestions or concerns <br />Sincerely, <br />L <br />Josh Wood
