HERBACEOUS PRODUCTION: The performance standard for this parameter is calculated similar to the cover performance standard, except that the factor of 2 is omitted. Where 520.1 = oven-dry ib/ac production in the Seneca II Mountain Brush reference area and 710.9 =oven-dry Ib/ac production in the Seneca II Sagebrush reference area. WOODY PLANT DENSITY: For purposes of illustration, woody plant density at the Seneca II Mine is evaluated in this document using a technical standard of year 2001 shrubs per acre. In future years, Woody Plant Density sampling will be refined such that special shrub planting uriats are defined and monitored separately from other areas at the mine. These special shrub planting units will be evaluated using a technical standard of year 2001 stems per acre and all other areas wilt be evaluated using a lower standard. Climatic Data SCC provided precipitation data from the Seneca II Mine for the period of January 1982 through September 2001. Since the long-term average for the mine exists for only 17 years, the long- term average monthly precipitation data from the National Oceanic and Atmospheric Administration (NOAH) for the nearby town of Hayden was used as an appropriate base for comparison. Information of degree-days was also derived from the NOAA records at Hayden. RESULTS Data from the 2001 revegetation monitoring studies at the Seneca I1 Mine are presented in Tables 1 through 15 contained in Appendix 1. The list of plant species observed during these studies (reclaimed and reference areas) are included in Table 16 in Appendix 2. Seed mixes applied on areas revegetated prior to 1981 and in years 1981 through 1993 are included for reference in Appendix 3. Photographs of representative locations within the reclaimed areas sampled in 2001, as well as photographs of the Mountain Brush and Sagebrush reference areas are included in Appendix 4. Graphic depiction of summaries of vegetation data, precipitation, and total degree days are presented in Figures 1 through 10 of this report. In the cover descriptions below, species listed as "also present' were not "hit" during point- intercept sampling but were present within one meter on, either side of the 50 m sample transect line. Cover percentages referred to in the following results as "percent of total vegetation cover" are relative vegetation values.
