for the nearby town of Hayden (Station 053867). Since the long -term average for the Seneca 11W mine <br />exists for only 26 years, the long -term average monthly precipitation data from Hayden (Station 053867) <br />was used as an appropriate base for comparison. Temperature data from the Hayden station was used <br />as well. <br />RESULTS <br />Sample data from the 2012 BRB PSCM -2 revegetation monitoring studies are presented in Tables A -1 <br />through 8. Sampling data are summarized in Appendix C. Data on cover, production, and woody plant <br />density are in Table C -1. Data on species density by lifeform are tabulated for sampled areas in Table C- <br />2. Data on relative cover by lifeform are compiled in Table C -3. Statistical adequacy of sampling is <br />reviewed in Table C -4. The list of plant species observed during these studies (reclaimed and reference <br />areas) is included as Table D -1. Seed mixes used in the reclamation areas are included for reference in <br />Appendix E. Photographs of representative locations within the reclaimed areas sampled 2012, as well as <br />photographs of Mountain Brush and Sagebrush Reference areas, are included in Appendix F. Graphs of <br />vegetation and climate data are presented in Figures C1 a through 11 of this report. <br />In the plant cover descriptions below, species listed as "also present" were not "hit" during point- intercept <br />sampling but were present within one meter of either side of the 50 m sample transect line. Unless <br />otherwise stated, all cover values are for absolute first -hit data only. Percentages are rounded to one <br />decimal place to facilitate discussion of the results. <br />2012 Phase Ill BRB PSCM -2 <br />(Photographs 1 through 23) <br />COVER <br />(Table A -1) <br />Introduced perennial cool season grasses were the predominant lifeform observed in Area BRB PSCM -2, <br />contributing 13.7 percent total first -hit vegetation cover. Of this, intermediate wheatgrass (Thinopyrum <br />intermedium) contributed the most with 5.9 percent followed by smooth brome (Bromus inermis) with 3.7 <br />percent first -hit vegetation cover. Native perennial cool season grasses were the second most observed <br />lifeform contributing 8.0 percent total first -hit vegetation cover, composed predominately of basin wildrye <br />(Leymus cinereus), Rocky Mountain fescue (Festuca saximontana) and western wheatgrass <br />(Pascopyrum smithi,). Additionally, introduced perennial forbs contributed 7.8 percent first -hit vegetation <br />cover, consisting primarily of alfalfa (Medicago sativa). Species encountered during quantitative sampling <br />included 27 native perennial forbs, 8 native annual / biennial forbs, 16 native perennial grasses, and 10 <br />native shrubs. A total of 98 species of vascular plants were encountered in quantitative sampling. <br />Included among these were the noxious weeds, houndstongue, musk thistle, Canada thistle and <br />Dalmatian toadflax (Linaria genistifolia ssp. dalmatica). Three of these noxious weed species had <br />11 <br />
