RESULTS AND DISCUSSION <br /> Vegetation cover, production and density means are discussed <br /> for each separate reference area and its corresponding vegetation <br /> type. Dominant species are selected for each type based on cover, <br /> production and density means. These dominant species are discussed <br /> in relation to their physical environment. <br /> The Maxwell Mine, including the grassland and pinyon-juniper <br /> types will be discussed first. Table 1 shows the mean cover values <br /> for the grassland reference area. Bouteloua gracilis had a mean <br /> cover value of 31 .30P'3, Artemisia fri ida had a mean cover value of <br /> 7.550, Carex eleocharis had a mean cover value of 3.5%, and <br /> Xanthocephalum sarothrae had a mean cover value of 2.70!,. The remain- <br /> ing grasses and forbs had mean cover values of 1 .8;', and below. Total <br /> mean cover for the grassland site was 52. 3'; . Bare ground accounted <br /> for 33. 5;, of sampled areas, litter accounted for 14. 0%J, and rock <br /> accounted for 0.2i'. (Tables are found in Appendix B. ) <br /> Production means for the grassland type are given in Table 2. <br /> Bouteloua gracilis had a mean production value of 23. 5 gins/in <br /> Artemisia frigida had a mean production value of 8. 1 gins/ni <br /> rStr-agalus 1_issour?ensis had a I-lean 7rodliction V31Ue Of 5.9 gn1S/1112, <br /> Xanthocephalum sarothrae had a nlean production value of 4. 9 gms/m`, <br /> and Carex eleocharis had a mean production value of 3.7 gms/ 2 <br /> m .
