Woody Plant Density Sampling - <br />Woody plant density was sampled at each point-intercept transed in the Reclamation <br />Areas. Woody plant density data were not taken in the Mountain Brush and Sagebrush <br />Reference Areas. All shrubs and subshrubs were tallied if their root crowns emerged <br />within the boundary of the (50m x 2m = 100 m2) transect. Both the number of woody <br />plants per 100sq.m. and a projected number of woody plants per acre were tallied and <br />presented in the data tables. <br />Photographic Record <br />Within each Reclamation and Reference Area, representative color photographs were <br />taken to document the appearance of the vegetation in 2002. <br />Plant Nomenclature <br />Plant nomenclature follows Weber and Wittmann 1992, as updated on the University of <br />Colorado Herbarium website. Details of nomenclatural note include: <br />• Thinopyrum intermedium and T. intermedium ssp. barbulatum were not <br />• distinguished. Further, as per Weber and Wittmann, T. intermedium is taken <br />to include the former Agropyron trichophorum. <br />• Elymus lanceolatus fm. dasystachya and E. 1. fm, psammophilus were not <br />distinguished; the two combined are reported here as Elymus lanceolatus. <br />^ E. 1. fm. albicans, the putative hybrid between Pseudoroegneria spicata ssp. <br />spicata and Elymus lanceolatus, has been separately identified because it is <br />so clearly different. <br />• Among big Sagebrush, no attempt was made to separate mountain big <br />Sagebrush (Seriphidium vaseyanum) from basin big Sagebrush (Seriphidium <br />tridentatum). Both occur in the native upland areas but most of pre-existing <br />Sagebrush and Reclaimed Area Sagebrush is mountain big Sagebrush. <br />Climatic Data <br />Precipitation data from the Colowyo Mine were provided for the period of January 1998 <br />through September 2002. The long-term averages for precipitation and temperature <br />were obtained from the Western Regional Climate Center's data for the Craig 4 SW <br />weather station located approximately 25 miles northeast of the Colowyo Mine. Climate <br />• data are graphically represented in Figures 1 through 7. <br />4 <br />
