• Herbaceous production samples within each reclaimed area or reference area totaled as <br />follows: <br />Area Number of 0.5 so. m. Plots <br />1990 Reclaimed Areas 20 <br />Mountain Brush Reference <br />Sagebrush Reference <br />25 <br />25 <br />Clipped material was returned to the ESCO laboratory and dried at 105 °C for 24 hours, then <br />weighed to the nearest 0.1 gm. <br />Shrub Density Sampling <br />Shrub density sampling was undertaken in the 1990 reclamation unit as well as the Wadge <br />Pasture reclamation unit of the Seneca II Mine. Shrub density was measured within 2 x 50 m <br />quadrats ("belt transects") oriented along the cover transect (where a cover sample was also <br />taken). In the two reference areas, no shrub sampling was conducted, since it had been <br />• sampled very extensively in previous years and resulting data would not have an effect on a <br />woody plant density performance standard. It should be noted that all big sagebrush <br />encountered were referred to Seraphidium tridentatum. <br />Total numbers of shrub density transects in each area were as follows: <br />Reclaimed Area Number of Transects <br />1990 Reclaimed Areas 20 <br />Wadge Pasture (Two-Stage) 45 <br />Mountain Brush Reference -- <br />Sagebrush Reference <br />All shrubs, including seedlings, with root crowns found within the quadrat boundaries were <br />tabulated by species and by life stages as follows: Seedling, Mature, or Dead. <br />The Wadge Pasture was sampled using atwo-stage statistical design as set forth in Chapter 10 <br />of Cochran (1977). The Wadge Pasture was divided into 20 equal-sized primary sample units <br />• and fifteen of these were randomly chosen to receive sampling (see Map 2, "Wadge Pasture 2- <br />stage sampling units"). Within each of the chosen primary sample units three (3) points were <br />3 <br />
