(WRCC) for the nearby town of Hayden (Station 053867). Since the long -term average for the <br />Seneca IIW mine exists for only 26 years, the long -term average monthly precipitation data from <br />Hayden (Station 053867) was used as an appropriate base for comparison. Temperature data <br />from the Hayden station was used as well. <br />RESULTS <br />Sample data from the 2011 interim revegetation monitoring studies are presented in Tables A -1 <br />through 11. Sampling data are summarized in appendix B. Data on cover, production, and <br />woody plant density are in Table B -1. Data on species density by lifeform are tabulated for <br />sampled areas in Table B -2. Data on relative cover by lifeform are compiled in Table B -3. <br />Statistical adequacy of sampling is reviewed in Table B -4. The list of plant species observed <br />during these studies (reclaimed and reference areas) is included as Table C -1. Seed mixes used <br />in the reclamation areas are included for reference in Appendix D. Photographs of representative <br />locations within the reclaimed and reference areas sampled in 2011 are included in Appendix E. <br />Graphs of vegetation and climate data are presented in Figures B1 through 10 of this report. <br />In the cover descriptions below, species listed as "also present" were not "hit" during point - <br />intercept sampling but were present within one meter of either side of the 50 m sample transect <br />line. Unless otherwise stated, all cover values are for absolute all -hit data only. Percentages are <br />rounded to facilitate discussion of the results. <br />In the production tables, data are expressed as oven -dry pounds per acre (lbs/acre). These <br />figures were extrapolated from the average weights for the 0.5 square meter samples. For woody <br />plant density, data collected in each 100 square meter plot were extrapolated to estimate the <br />number of individuals expected per acre. <br />Interim Monitoring <br />2007 RECLAIMED AREA <br />(Photographs 1 -7) <br />Cover <br />(Table A -1) <br />Introduced annual and biennial forbs were the predominant lifeform observed in the 2007 <br />Reclaimed Area, contributing 19.3 percent all -hit cover. Of this, yellow sweet clover (Melilotus <br />officinalis) and prickly lettuce (Lactuca serriola) contributed 10.7 and 4.3 percent all -hit cover, <br />respectively. Native perennial cool season grasses were the second most encountered lifeform <br />with 17.1 percent all -hit cover. Within this group, western wheatgrass (Pascopyrum smithir) and <br />6 <br />
