Recommended Vegetation Management Procedures <br /> Establishment Phase <br /> This site should not be mowed and/or driven on if very wet soil conditions exist at <br /> the time of the maintenance visit, to avoid rutting and compaction. <br /> Year 1: <br /> Complete site mowings to control annual/biennial weed canopy and <br /> prevent production of viable seed. Three mowing trips are typical depending <br /> on soils, weather patterns and planting dates. Due to the type of grasses <br /> found on Nguyen, three mowing trips in the first year are recommended to <br /> prevent panel shading and control weed growth. <br /> • Mowing to be done using specialized zero-radius mowers and/or flail <br /> mowers <br /> • Target mowing height of 4-6 inches. <br /> Year 2 <br /> • Complete site mowing to control annual/biennial weed canopy and prevent <br /> production of viable weed seed. <br /> • Two mowing trips likely along with the use of herbicides as necessary during <br /> both trips. <br /> • Mowing to be done using specialized zero-radius mowers and/or flail <br /> mowers. <br /> Year 3 <br /> • Integrated Vegetation Management using mowing and spot spraying <br /> depending on growth and weed populations. <br /> • Two trips likely in Year 3. <br /> Maintenance Phase <br /> Years 4 - 34: Integrated Vegetation Management <br /> • Two IVM site visits are typical depending on vegetation status. <br /> • Each visit will likely include mowing, spot herbicide applications and/or <br /> herbicide wicking. <br /> • Equipment used includes tractor and/or ATV mounted sprayers. <br /> • Include a complete site mowing once every 3 years to mulch up biomass <br /> and recycle nutrients. <br /> Natural <br /> Resource <br /> 12 Services <br />
