All shrubs within a strip 45 x 5 m were counted by <br />species aid number per hectare detevnined. 1te<ity transacts were surveyed in <br />the upland c.,~m/.n+ch affected ama a[d 15 on t}e upland Sagebrush control site. <br />T4ZE£ DH7.SITY AND BASAL~ARFA INTA <br />Since tree ablmumities on the site were small and contained few trees, a <br />cas~lete Can i'nS technique w0s 1LSed t0 CO1leCt density and basal area data <br />(basal area is the arm of a plane passed through the start of a tree at <br />right angles to its longitudinal axis at breast height). This entailed <br />counting all trees wlthln the mimtmity a~ recording cizciuoference at <br />breast height (cbh) in caitimeters for each. Since the areal extent of <br />each mnmmity could be obtained by polar planimetry techniques, number <br />of trees per unit area (i.e., trees/acre) was easily obtained. Likewise, <br />basal area was directly convertible fran cbh measurements. <br />VD~i7iTIQ4 SPDCIFS QY4PQSITICYV <br />Reconnaissance type surveys were cmducterl within each vegetation type on <br />all affected and control areas to obtain a complete listing of vegetation <br />species for the study area. Surveys were conducted by a plant taxonanist <br />durixg a minimum of two days each ironth thTwghout the growing season <br />(early May through Auqust). A plant voucher collection was prepared for <br />all planC species identified during this study and has been suLnitte3 to <br />the Nucla Mine m be maintained on pe+*u*+a++t file. As additional species <br />are verified, C-ki?~ will be added to the on-site plant collection. For <br />each plant collec"keily LiAE°, habitat, elevation aryl associated species were <br />recorded. 4uestionable plants were positively identified at the Rocky Mountain <br />Herbarium in Laramie, Wyoming or at the U.S. Forest Service Herbarium in <br />Ft.
