Tamarisk control methods include mechanical removal or cutting <br />the stem and applying herbicide (known as the cut -stump method). <br />Individual tamarisk plants will be cut as close to the ground as <br />possible and herbicide will be applied immediately thereafter to the <br />perimeters of the cut stems. The herbicides used will be triclopyr <br />(e.g. Garlon4 or Pathfinderll) or imazapyr (Arsenal). Fall <br />treatments are believed to be most effective because the plants are <br />translocating materials to their roots. <br />Annual evaluations of areas treated will monitor the effectiveness <br />of the program and the need for additional treatments. <br />Additional weed control may include control of any type of <br />vegetation which may grow around substations, buildings, <br />conveyors, within 100' of mine portals, and other areas where <br />vegetation may present a fire hazard. <br />(vi) Revegetated areas will be monitored to determine the success of <br />plant establishment and stand development. Monitoring will consist <br />of both qualitative and quantitative observations. At the end of the <br />first full growing season following seeding, the reclaimed areas will <br />be visually evaluated to determine areas which may require <br />reseeding. Annual visual inspection of the reclaimed sites will <br />continue during the responsibility period. <br />In year 4, vegetation cover will be evaluated for the reclaimed sites. <br />Both total cover and species cover will be determined. A minimum <br />of 10 cover samples will be collected in each reclaimed unit. <br />Sampling methodology will be conducted as described on page 14- <br />19. This data will be used to evaluate if established vegetation is <br />developing effectively. Year 6 vegetation evaluations, which were <br />discontinued with the approval of MR -78, were also performed on <br />reclaimed sites through 2012. <br />In years 9 and 10, the sampling design and procedure for the final <br />bond release evaluation will be conducted as described on page <br />14-19 or as described on appendix page A14-11-4, depending on <br />the size of the reclaimed units. <br />Ongoing monitoring has determined that livestock grazing may <br />affect the establishment of vegetation at the south fan and RSRDA <br />borrow area. For this reason, fencing was installed in 2005 to limit <br />grazing in these areas. Additionally, fencing was installed to limit <br />pedestrian and vehicular degradation of the greasewood reference <br />area. <br />MR -86 14-18 (Rev. 04/18) <br />
