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 quadrant sampling method that meets the <br />provisions of DRMS Regulation 4.15.11 (1)(b)(1). The observational unit will be a circular plot <br />frame of at least one quarter square meters in diameter and large enough to encompass individual <br />plants of the larger species being sampled. Current year growth of perennial herbaceous non - <br />woody species will be clipped by plant life forms within each quadrant. The sampled plant <br />material will be bagged and taken to the laboratory for drying and weighing. Samples will be <br />oven -dried at 105 degrees C for a period of 24 hours or until a constant weight is attained, as <br />recommended on page 8 of the Vegetation Guideline. <br />Transect locations will be located by using a random number generating procedure to create up <br />to 50 random coordinate pairs within the reclamation study area. A geographic positioning <br />system (GPS) unit will be used to navigate to the sample points, in the order that the points were <br />randomly generated. Cover transects will be oriented along a random compass bearing from the <br />point of origin. Typically, if production sampling is done concurrently with cover sampling, <br />randomly located one-quarter square meter or larger quadrants will be placed along the transect <br />tape. Cover will be calculated as percent total cover for each transect, and the mean calculated <br />for the study area. Production will be calculated by multiplying the sample dry weight and <br />converted to pounds per acre. <br />Management Plan for the Irrigated Pasture Reference Area <br />WFC owns the reference area and controls all of the management aspects of this site. The same <br />reclamation contractor who manages the reclaimed area will manage the reference area. This is <br />not the case with any other potential Irrigated Pasture area within a reasonable distance of the <br />NHN mine permit area. <br />The reclamation contractor will release water into the reclaimed area and the reference area from <br />the CCC ditch at the same time. The flood irrigation of the reference area will be regulated to <br />simulate the same plant application rate and conditions of the side roll irrigation of the reclaimed <br />area. Flood irrigation may also be employed in the reclaimed area. The irrigation method in all <br />reclaimed Irrigated Pasture reclaimed areas was flood irrigation prior to mining. <br />The expected application rate of water: Water will be applied to the reference area based on the <br />ratio used for the irrigation of reclaimed Irrigated Pasture on the Garvey property. <br />Plans for livestock grazing: The reference area will be grazed by cows in late June, after any <br />vegetation studies are completed. The livestock will be removed by the end of June, and the <br />reference area will not be further grazed by livestock during the growing season.
