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 />Map 2.05.4(2)(e) - 2 shows the location of the Reclaimed Irrigated Pastureland reference area and <br />Map 2.05.4(2)(e)-4 shows the dryland reference area. Attachment 2.05.4(2)(e) - 5 shows the <br />Statistical Data of the 2007 Sampling of the Reclaimed Irrigated Pastureland Reference Area. <br />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 <br />and woody vegetation, as defined by DRMS Regulation 4.15.8(3)(b). Herbaceous production <br />will be measured as current year above -ground biomass of herbaceous vegetation, as defined by <br />DRMS Regulation 4.15.8(4). <br />Vegetation sampling for measuring reclamation success will be conducted to ensure a <br />repeatable and unbiased estimate of each vegetation population parameter. Measurements <br />made on the reference area will be done in the same manner and season as measurements made <br />on reclaimed lands, to ensure valid comparisons as specified in DRMS Regulation 4.15.11(1). <br />Measurements will be typically made in late May to early June, although the timeframe is <br />subject to variation associated with weather conditions and irrigation water availability. <br />Sampling will be conducted within two weeks prior to 1st cut harvest of the reclaimed fields <br />and prior to any growing season livestock grazing in the reference area. <br />Vegetation cover will be measured by a point intercept method that meets the provisions of <br />DRMS Regulation 4.15.1 l(1)(a)(i). The observational unit will be a series of predetermined <br />random intervals along a transect tape at least 5 meters in length, where 10 predetermined <br />randomly selected intervals will be used to collect 100 data points. A point sampling device <br />supported by a rigid frame will be used to ensure unbiased and vertical point placement. <br />January 2015 TR -66 2.05.4(2)(e) - 23 <br />
