Performance Standards <br />COVER and HERBACEOUS PRODUCTION: For purposes of comparison only, <br />cover and herbaceous production performance standards were calculated in <br />accordance with procedures contained in the Seneca IIW permit. Aline that <br />indicates 90 percent of this standard has been placed on-Figures 1a and 2 for <br />informational purposes. At such time as bond release is formally sought, <br />revegetation wilt be considered successful for cover when mean cover for a bond <br />release block is at least 90% of the calculated success standard or approved <br />technical standard. <br />WOODY PLANT DENSITY: For purposes of comparisons in this document, <br />general (background) woody plant density at the Seneca IIW Mine is evaluated <br />using a technical standard of 200 shrubs per acre. Shrub concentration areas <br />such as may be included in eventual bond release blocks are judged by a <br />standard of 2000 stems•per acre. No shrub concentration areas were sampled in <br />2005. <br />Climatic Data <br />Precipitation data were collected at the Seneca IIW Mine during the period 1990 <br />through 2005. For years 1982 through 1989, SCC provided precipitation data <br />from the nearby Seneca II Mine. Since the data record for Seneca II exists for <br />only 21 years, the long term average monthly precipitation data from the Western <br />Regional Climate Center (WRCC) for the nearby town of Hayden was used as an <br />appropriate base for comparison. Information on degree-days was based on <br />temperature data from the Seneca met station 2 at the Seneca IIW Mine. <br />RESULTS <br />All numerical data are found in Tables 1-12 of Appendix 1. Data are summarized <br />in Tables 13-15. Sample data for cover, herbaceous production, and woody plant <br />density are summarized in Table 13, and data on species density by lifeform are <br />
