species. All foliage was clipped within a vertical projection of the quadrat sides. r• <br />Project number, plot number contents, date, and wet weight were recorded on each bag. <br />Upon return from the field, clipped samples were oven-dried at 105°C for 24 hours after <br />which they were reweighed and the dry weights recorded. <br />See Appendix 10-8 for a discussion of 1985 tie across haul road production sampling <br />methodologies. <br />Density. Shrub density on sagebrush and mixed brush vegetation types within the mining <br />2 <br />area, the haul road vegetation types, and the related reference areas was measured in 4m <br />(2 m x 2 m) plots during 1980. The center point of a cover-productivity plot represented <br />the lower left-hand corner of the shrub density plot. A shrub was defined as a <br />discernible crovm from which one or mare stems arose. <br />Shrub density in the Aspen affected and reference areas was sampled within 1 m x 50 m belt <br />transects located along the randomly oriented cover transects in 19 83. Within these belt <br />transects, each shrub having its root crown within the boundary was counted by species and <br />ht of <br />th <br />h <br />i th <br />fi <br />t tw ecies was <br />individuals of e <br />h <br />h <br />b measured <br />Trees below ~• <br />g <br />e <br />e e <br />rs <br />o ac <br />s <br />ru <br />sp . <br />breast height (1.3 m) also were counted by species. Shrub density data are presented as <br /> <br />number per 50 0 <br />mom, number per <br />hectare, and number per acre. <br />In 1983, tree density in the Aspen affected and reference areas was sampled using 5 m x <br />50 m belt transects or quadrats. Each quadrat had its long axis along the randomly <br />oriented cover transect line originating at a grazing exclosure. Within each quadrat, all <br />trees greater than breast height (1.3 m) were counted by species, noted as live or dead, <br />and measured at breast height for diameter in cm. <br />Tree densit data are ex res sed as number of stems 2 <br />y p per 250 m , number of stems per <br />hectare, and number of stems per acre.
