RESULTS AND DISCUSSION <br />Those studies dealing with the entire study area, exclusive of individual <br />vegetation types are presented first. These include vegetation type <br />_ mapping and vegetation species c~rq~osition. Baseline vegetation data <br />such as shrub height and density, shrub and tree age, tree density and <br />basal area, cover, frequency and productivity gathered in different <br />vegetation types at Seneca II Mine are presented below. A description of <br />the major vegetation types found on the study area based on the various <br />vegetation parameters measured, an evaluation of sampling adequacy <br />and equality between control and affected areas concludes the report <br />section. Raw and analyzed data are provided on computer print-outs in <br />Appendix B. Summary tables are utilized in the text where appropriate. <br />heather conditions within a given year, notably the acrount and ironthly <br />distribution of precipitation, can have a considerable effect on certain <br />vegetation parameters, especially productivity which, during unusually <br />wet years, may increase dramatically. Therefore, in the interest of <br />qualifying the vegetative data base presented in the report for the 1979 <br />gra.,ring season, precipitation data gathered at a weather station located <br />approximately 25 miles from the study area are included for the 1979 <br />growing season and for the six months preceeding the 1979 growing <br />season (Table 2). Precipitation data for the six-nnnth period prior <br />to the growing season is important because the arount and distribution <br />of precipitation during this period influences total soil tmisture <br />available to plants during the subsequent growing season. <br />L• <br />-21- <br />
