found that the use of straw mulch introduces undesirable weedy species into the <br /> reclaimed area and will thus not be required. 12. 7 acres were reseeded at the facilities <br /> area in 2011. <br /> Revegetation success will be monitored qualitatively through visual observations. <br /> Quantitative sampling shall occur in the 3rd and 6th years after reclamation (2014 and <br /> 2017)for cover, species, production, and woody plant density. <br /> Reclamation success will be determined by comparison with associated reference areas. <br /> Cover in the reclaimed areas will be estimated by the point-intercept method and shall <br /> be deemed acceptable if it is greater or equal to 90% of the cover in the appropriate <br /> reference area with 90% statistical confidence. There are four approved reference areas; <br /> Dryland pasture, Improved pasture, Rangeland and Meadow. The locations of the <br /> reference areas are shown on Map 20- 1 in the PAP. <br /> Vegetation production will be measured by harvesting 1/2 m2 to 1 m2 plots in both <br /> reclaimed and reference areas. If production in the reclaimed area is 90% or more of the <br /> production of the associated reference area at a 90% statistical confidence, it shall be <br /> deemed acceptable. <br /> Neither dryland pasture nor improved pasture designations will be required to meet a <br /> species diversity standard since post-operational land use will be for agricultural use. <br /> The rangeland areas will be differentiated by either upland rangeland or lowland <br /> rangeland. Upland rangeland will establish 5 perennial grasses with 50% or greater <br /> frequency each. Three of these grasses will contribute greater than I% relative cover. A <br /> minimum of two forbs will be established with an occurrence of 50% or greater. At least <br /> one shrub will be established with a frequency of 10% or greater. On lowland rangeland, <br /> six grasses shall be established each with 50% or greater frequency (with four of the <br /> grasses contributing more than one percent relative cover each). A minimum of one <br /> forb, with greater than 50%frequency, will be present in the lowland rangeland type. <br /> Species diversity in the reclaimed areas along the TAHR corridor will be concentrated <br /> on the herbaceous component. The shrub component will rapidly reestablish naturally <br /> from the surrounding undisturbed vegetation. In the low sagebrush vegetation type <br /> associated with the TAHR, baseline studies identified three grasses with relative cover <br /> greater than three percent. No forbs with relative cover values of three percent or more <br /> were found in the baseline study. Thus, a minimum of three grasses will be established <br /> and each will contribute relative cover values of three percent or greater. Each species <br /> will not exceed 40 percent relative cover and the total of the three species will not <br /> exceed 75 percent relative cover. In addition, two forbs and one shrub will be <br /> established, but no relative cover values are specified. <br /> In the meadow vegetation type of the TAHR, four grasses contributed relative cover <br /> greater than three percent in baseline studies. No forbs contributed relative cover values <br /> of three percent or more, and shrubs were not a notable component of the type. A <br /> minimum of four grasses each will contribute relative cover values of three percent or <br /> 26 <br />
