x =sample mean for shrub density data. <br /> <br />I <br />After an adequate sample had been collected, an assessment of the percent that these <br />"sufficiently dense" patches comprise of the total BRB-3 area was made. <br />The criterion for formal for judgement of the adequate stocking of woody plants on the Seneca II <br />site is as follows: <br />Overall average density ? 100 stems per acre with at least 5% of the BRB-3 area oossessing s <br />1000 stems per acre. <br />HYPOTHESIS TESTING APPROACHES -BRB-4REV <br />For BRB-4rev, in which formal hypothesis testing relative to Phase II Bond Release was pursued, <br />the following procedures were followed: <br />Cover <br />Percent absolute (foliar) first hit herbaceous vegetation cover of BRB-4rev 2 90% of TWICE the <br />weighted absolute (foliar) first hit herbaceous vegetation cover from the reference areas <br />(weighted based on 83% original extent of Mountain Brush /Aspen and 17% original extent of <br />Sagebrush/Snowbeny). The factor of 2x the reference area first hit herbaceous cover of the <br />reference areas is contained in the Seneca 11 permit document. <br />Statistical tests used were as for BRB-3 cover. <br />Climatic Data <br />SCC provided precipitation data for the Seneca II Mine for the period of January 1982 through <br />September 2006. Since the long-term average for the mine exists far only 22 years, the long- <br />term average monthly precipitation data (56 years) from the Western Regional Climate Center <br />(WRCC) for the nearby town of Hayden was used as an appropriate base for comparison. SCC <br />also provided temperature data for the nearby Seneca IIW Mine in 2006; these data were used <br />for temperature analysis on the Seneca II Mine. <br />RESULTS <br />Numerical data are found in Tables 1 through 16 of Appendix 1. Sample data from the 2006 <br />revegetation monitoring studies at the Seneca II Mine are presented in Tables 1 through 12. <br />13 <br />
