The Airport Dryland Reference area is located within the fenced boundaries of the Nucla Airport <br />and is protected from domestic livestock grazing. Wildlife (deer, elk) winter grazing will still be <br />allowed, as is on the NH2 reclaimed land. If the airport authorities allow domestic grazing, then <br />WFC has an agreement with the airport authorities to fence off the three plus acre reference <br />area so the vegetation will not be affected. <br />For Dryland 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 <br />the reclaimed areas and the reference area will be used to determine revegetation success, as <br />described below. Vegetation cover will be measured as either canopy cover or basal cover of <br />living herbaceous and woody vegetation, as defined by CDRMS Regulation 4.15.8(3)(b). <br />Herbaceous production will be measured as current year above - ground biomass of herbaceous <br />vegetation, as defined by CDRMS 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 <br />made on reclaimed lands, to ensure valid comparisons as specified in DRMS Regulation <br />4.15.11(1). Measurements will be made at a time during the May through September growing <br />season. <br />Vegetation cover will be measured by a point intercept method that meets the provisions of <br />DRMS Regulation 4.15.11(1)(a)(i). The observational point 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 />Herbaceous production will be measured by a quadrat sampling method that meets the <br />provisions of DRMS Regulation 4.15.11(1)(b)(i). The observational unit will be a rectangular or <br />circular plot frame at least % square meter and large enough to encompass individual plants of <br />the larger species being sampled. Current year growth of herbaceous non -woody species will <br />be clipped within each quadrat. The sampled plant material will be bagged and taken to the <br />laboratory for drying and weighing. Samples will be oven -dried at 105 degrees C to a constant <br />weight. <br />August 2013 PR -08 2.05.4(2)(e) - 57 <br />
