reclaimed Irrigated Pasture type will be based on herbaceous production and allowable plant <br />cover. <br />Nearly all farmers in the Nucla area harvest their irrigated fields at least one time during the year. <br />There are a few, who attempt a second and third cutting but the majority of the production comes <br />from the 1st cutting. The success standard for WFC's reclaimed Irrigated Pasture will involve a <br />statistically adequate sampling based comparison to the approved reference area which was <br />approved for the NH2 Mine in connection with TR -58 in 2008. <br />Map 2.04.10-3 shows the location of the 6.81 acre Irrigated Pasture Reference Area, located to <br />the south of the existing New Horizon Mine office and Map 2.04.10-4 shows the location of the <br />approved NH2 Dryland Pasture Reference Area, located near the Nucla airport. <br />Vegetation sampling for measuring reclamation success will be conducted to ensure a repeatable <br />and unbiased estimate of each vegetation population parameter. Measurements made on the <br />reference area will be done in the same manner and season as measurements made on reclaimed <br />lands, to ensure valid comparisons as specified in DRMS Regulation 4.15.11(1). Measurements <br />will be made in late May to early June immediately prior to 1St cut harvest of the reclaimed fields <br />and prior to any growing season livestock grazing in the reference area. <br />For all reclaimed Irrigated Pasture areas, vegetation cover and herbaceous production will be <br />measured at reclaimed sites and the corresponding reference area. Comparisons of the mean <br />parameter values between the reclaimed areas and the reference area will be used to determine <br />revegetation success, as described below. Vegetation cover will be measured as canopy cover of <br />living plant species, as defined by DRMS Regulation 4.15.8(3)(b). For cover success standards, <br />the cover in the reference area will be compared to the cover in the reclaimed area with no <br />weighted average adjustments for soil type. Herbaceous production will be measured as current <br />year aboveground biomass of herbaceous vegetation, as defined by DRMS Regulation 4.15.8(4). <br />Vegetation cover will be measured by a point intercept method that meets the provisions of <br />DRMS Regulation 4.15.11 (1)(a)(1). The observational unit will be a series of points along a <br />transect at least 5 meters and typically 50 meters in length and with at least 50 data points at <br />regular or random intervals along the transect. A point sampling device supported by a rigid <br />frame will be used to ensure unbiased and vertical point placement. <br />Herbaceous production will be measured by a quadrant sampling method that meets the <br />provisions of DRMS Regulation 4.15.11 (1)(b)(1). The observational unit will be a rectangular or <br />circular plot frame of at least one-quarter square meters in diameter and large enough to <br />encompass individual plants of the larger species being sampled. Current year growth of <br />herbaceous non -woody species will be clipped by life forms within each quadrant. The sampled <br />plant material will be bagged and taken to the laboratory for drying and weighing. Samples will <br />be oven -dried at 105 degrees C to a constant weight. <br />Section 2.05.4(2)(e) Page 12 May 2015 <br />
