2.05.4(2)(e) <br />The species diversity standard will be based on the Disturbed Meadow data in <br />that two perennial, non -noxious species will be present that have a relative <br />cover exceeding 3%. <br />Drill Sites and Roads <br />The Operator will determine the vegetation success of the Mesic Mountain <br />Shrub, Aspen and Xeric Mountain Shrub revegetated areas for cover and <br />production by comparing the vegetation on the revegetated areas to the <br />reference area as follows: <br />• Vegetation Cover — Achieve 90% of the perennial vegetation cover of <br />the approved reference area sample mean at the 90% confidence level. <br />• Herbaceous Production — Achieve 90% of the total herbaceous <br />production of the approved reference area sample mean at the 90% <br />confidence level. <br />• Woody Plant Density — No standard. <br />The species diversity standard for the drill sites and roads will be based on the <br />reference area which exhibited three native, perennial grass species and two <br />native perennial forb species with greater than 1 % relative cover. <br />Since the intent of the revegetation plan is to balance the grass forage <br />production against the shrub cover needs of wildlife, no woody stem density <br />success criteria shall apply to any of the reclaimed areas. However, the <br />Operator will plant some small shrub clumps (from one two three acres in <br />size) interspersed throughout the reclaimed area as shown on Map 18. The <br />shrub clumps will not be subjected to any intensive management measures. <br />However, the clumps will be temporarily fenced if wildlife browsing proves <br />to be a limiting factor in the establishment of the shrub clumps. The <br />boundaries of the shrub clumps will be marked in the field. <br />Revegetation success standards for vegetation communities disturbed at the <br />loadout are presented in the February 2001 Baseline Vegetation Inventory in <br />Volume III, Tab 5. <br />The operator will perform additional field studies during the 2009 calendar year <br />to address mountain shrub/xeric mountain shrub community delineation, <br />reference area comparability, and success demonstration approaches. The <br />report/revision will be submitted during the first quarter of 2010. <br />TR -101 2.05-78 06/15 <br />
