RESULTS <br />Data from the 1993 revegetation monitoring studies at the Seneca II Mine are presented in <br />Tables 1 through 26 contained in Appendix 1. The list of plant species observed during these <br />studies in the reclaimed and reference areas are included in Table 27 in Appendix 2. Seed mixes <br />applied on areas revegetated prior to 1981 and in years 1981 through 1991 are included for <br />reference in Appendix 3. Site data from sample transacts (orientation, slope, aspect, and <br />initials of samplers) are included as Appendix 4. Photographs of representative locations <br />within the reclaimed areas sampled in 1993, as well as photographs of the Mountain Brush and <br />Sagebrush reference areas are included in Appendx 5. Graphic depiction of summaries of <br />vegetation data, precipitation, and total degree days are presented in Figures 1 through 10 of <br />this report, starting on page 36. In the following descriptions, species that were encountered <br />quantitatively (i.e. 'hit' by a sample point) are described first for a particular lifeform; <br />species listed as 'also present were not hit but were present within one meter to either side of <br />the sample transact. <br />Pre-Law Reclaimed Areas (Photographs 1 through 3) <br />Cover <br />Introduced perennial cool season grasses dominated this reclamation unit with 50.4 percent of <br />total vegetation cover (Table 1). More than half of this percentage was provided by <br />intermediate wheatgrass (Thinopyp~m intermedium). Smooth brome (Bromppsis inermisl <br />contributed almost all of the remaining half of Phis percentage. Other species contributing to <br />this lifeform's total vegetation cover were; desert wheatgrass (Aaroovr on cristatum and A. <br />cristatum ssp. desertoruml, meadow barley (Critesion brachvantheru ml, orchard grass <br />(Dac lie glomeratal, tall fescue (Festuca arundinaceal, timothy (Phle um pratensel, and <br />Kentucky bluegrass (Poa pratensisl. Meadow fescue (Festuca pLtens isl and bristlegrass <br />(Setaria viridisl were also present. Native perennial cool season grasses and grass-like plants <br />accounted for 2.7 percent of total vegetation cover. More than haH of this cover percentage was <br />contributed by Agassiz bluegrass (Poa agassizensisl. Other species offering measurable cover <br />were beaked sedge (Carex utriculatal, (oxtail barley (Critesio~iubatu ml, slender wheatgrass <br />(~~j/mus trachy a ~I ~~ ssp. trachycaulusl, American manna-grass (Glvi ceria gfandisl, and <br />Canada bluegrass (Poa comnressa).
