For Irrigated Pasture areas, vegetation cover and herbaceous production will be measured at <br />reclaimed sites and the reference area. Comparisons of the mean parameter values between the <br />reclaimed areas and the reference area will be used to determine revegetation success, as <br />described below. As described above in this section, the production standard is adjusted for soil <br />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 made in late May to early,June, immediately prior to 1S "cut:ha'rvest 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 DRMS <br />Regulation 4.15.11(1)(a)(i). The observational unit will be a series of points along a transect at <br />least 5 meters in length, and at least 50 data points at regular intervals along the transect. A point <br />sampling device supported by a rigid frame will be used to ensure unbiased and vertical point <br />placement. <br />Herbaceous production will be measured by a quadrat sampling method that meets the provisions <br />of DRMS Regulation 4.15.11(1)(b)(i). The observational unit will be a rectangular or circular plot <br />frame at least '/4 square meter and large enough to encompass individual plants of the larger <br />species being sampled. Current year growth of herbaceous non -woody species will be clipped <br />within each quadrat. The sampled plant material will be bagged and taken to the laboratory for <br />drying and weighing. Samples will be oven -dried at 105 degrees C to a constant weight. <br />Revised April /09 TR58 2.05.4(2)(e) -19L vp -5 9 <br />)3 May 2&i <br />
