For cover success standards, the cover in the reference area will be compared to the cover in the <br />reclaimed area with no weighted average adjustments for soil type. <br />Attachment 2.05.4(2)(e) - 4 shows the location of the new Reclaimed Irrigated Pastureland <br />reference area in addition to the dryland reference areas near the Nucla airport. <br />Attachment 2.05.4(2)(e) - 5 shows the Statistical Data of the 2007 Sampling of the Reclaimed <br />Irrigated Pastureland Reference Area. Cover and Production data are included. <br />For Reclaimed Irrigated Pastureland areas, vegetation cover and herbaceous production will be <br />measured at reclaimed sites and the reference area. Comparisons of the mean parameter values <br />between the reclaimed areas and the reference area will be used to determine revegetation <br />success, as described below. As described above in this section, the production standard is <br />adjusted for soil types in the reclaimed area vs. the reference area. <br />Vegetation cover will be measured as either canopy cover or basal cover of living herbaceous and <br />woody vegetation, as defined by DRMS Regulation 4.15.8(3)(b). Herbaceous production will be <br />measured as current year above - ground biomass of herbaceous vegetation, as defined by DRMS <br />Regulation 4.15.8(4). <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 typically made in late May to early June, although the timeframe is subject to variation <br />associated with weather conditions and irrigation water availability. Sampling will be conducted <br />within two weeks prior to 1s` cut harvest of the reclaimed fields and prior to any growing season <br />livestock grazing in the reference area. <br />Vegetation cover will be measured by a point intercept method that meets the provisions of DRMS <br />Regulation 4.15.11(1)(a)(i). The observational unit will be a series of predetermined random <br />intervals along a transect tape at least 5 meters in length, where 10 predetermined randomly <br />selected intervals will be used to collect 100 data points. A point sampling device supported by a <br />rigid frame will be used to ensure unbiased and vertical point placement. <br />(June 2013 MR 86) 2.05.4(2)(e) - 26 W -a&� <br />"vg Juh , 1-013 <br />
