• completed in each of the two reference areas (Mountain Brush and Sagebrush). Interceptions <br /> were used to calculate absolute foliar cover by dividing the number of interceptions for a <br /> particular species or material by the total number of points taken (50). <br /> Production Sampling <br /> Production sampling was done in reclamation areas B through H and the two reference areas. <br /> Herbaceous production sampling was accomplished using one-half square meter (0.5 m2) <br /> quadrats within which all herbaceous growth in a vertical projection was removed by Gipping <br /> and placed in labeled paper bags. Categories into which clipped material was placed were: <br /> Native Annual (and biennial) Forbs <br /> Introduced Annual (and biennial) Forbs <br /> Native Annual Graminoids <br /> Introduced Annual Graminoids <br /> . Native Perennial Forbs <br /> Introduced Perennial Forbs <br /> Native Perennial Graminoids <br /> Introduced Perennial Graminoids <br /> Alfalfa (Medicago saliva) <br /> Cicer Milkvetch (Astragalus ricer) <br /> Clipped material was returned to the ESCO laboratory and dried at 105 o C for 24 hours, then <br /> weighed to the nearest 0.1 gm. Determination of native or introduced status was made using <br /> Weber and Johnston (1979) as a reference. <br /> Shrub Density Sampling <br /> Shrub density sampling was undertaken in reclamation areas B through H and the two reference <br /> areas. Shrub density in reclaimed areas was measured within 2 x 50 m quadrats ( 'belt <br /> transects") oriented along the cover transect (where a cover sample was also taken). Shrub <br /> density sampling intensity in the reclaimed areas was greater than cover sampling, so that in <br /> • addition to the twenty (20) shrub density samples taken along the cover transects, thirty <br /> (30)more were located independently, making a total of fifty (50) such samples in each <br /> 2 <br />
