• sample, taken at a randomly selected location, consisted of 50 projected points spaced at 1 m intervals <br />along a randomly oriented 50 m transact. Transacts were completed in each of the sampling areas at <br />the locations shown on Exhibit 10.1. Absolute foliar cover was calculated by dividing the number of <br />interceptions for a particular species or material by the total number of points taken (50). Data shown <br />for each sample in the cover tables are first hit data; these data and the resulting absolute foliar, <br />litter, rock and bare soil cover calculations are directly useful in performance standard considerations <br />and in soil loss model calculations. In addition, percent relative cover was calculated by species and <br />lifeform and is presented in the far right column of the cover data tables. <br />All vegetation types within the Expansion Area, as well as the Pond 009 area (see above), were <br />sampled for cover, es were the Aspen Woodland, Western Wheatgrass/Alkali Sagebrush, Mixed Brush, <br />and Sagebrush types in the existing Permit Area. The latter were sampled to facilitate comparison <br />between the Expansion Area and existing Permit Area. <br />Production Sampling <br />Herbaceous production sampling was accomplished using one-half square meter (0.5 m2) circular <br />• quadrats within which all herbaceous growth in a vertical projection was removed by clipping and <br />placed in labeled paper bags. <br />Clipped material was returned to the ESCO laboratory and dried at 105 o C for 24 hours, then weighed <br />to the nearest 0.1 gm. <br />Woody Plant Density Semolina <br />Woody plant density in sampling areas was measured within 1 x 50 m quadrats (shrubs) and 5 x 50 m <br />quadrats (trees, ie. aspen) oriented along the cover transact (where a cover sample was also taken). <br />Woody plant density sampling intensity in the study areas was often greater than cover sampling, since <br />variance of woody plant counts makes achievement of an adequate sample size more difficult. <br />Additional woody plant density plots were located randomly as previousty discussed. All woody plants, <br />including seedlings, with root crowns found within the quadrat boundaries were tabulated by species and <br />by life stages as follows: seedling, mature, or dead. For shrubs that sprout from along-lived root <br />system, such as snowberry, serviceberry, Gambel's oak, and chokecherry ,individuals were counted <br />as'clumps' that appeared to originate from the same central root system. Aspen were counted as <br />individual stems, even though it is well known that the trees in a typical aspen stand may represent the <br />• <br />2 <br />
