n <br />LJ <br />2.0 METHODS <br />2.1 VEGETATION TYPE DELINEATION AND MAPPING <br />Vegetation types within the study area were delineated and mapped on 1" _ <br />2000' color aerial photographs and 1" = 400' blue-line photomosaic base maps <br />provided by the Consolidation Coal Company. <br />Differences in shading and texture were used as a guide in delineating <br />vegetation types. The vegetation map was ground truthed in the field during <br />the course of other segments of the study. Vegetation types greater than two <br />acres in size were mapped separately. <br />2.2 SPECIES LIST <br />• A list of vascular plant species was compiled from species observed <br />during the course of field work conducted in summer of 1984. Species <br />observed were identified in the field with the use of floral keys by <br />Harrington (1964), Hitchcock & Chase (1951), and Weber (1976). Notes were <br />made as to the date of collection, location of collection, the habitat, <br />exposure, slope, elevation, soil, and collector. Dried specimens were <br />verified by Dr. William Weber at the University of Colorado Herbarium. <br />Specimens not readily identified in the field were collected in standard <br />herbarium manner. <br />Weedy species were determined using Thornton et al. (1974). The <br />authorities for scientific names were obtained from Weber and Johnson (1979). <br />Common names were taken from the USDA Forest Service (1976). <br />2 <br />Exhi6rt ]0, Item 5 Revision Date: 03/06/07 <br />7 Revision No.: PR-02 <br />
