`-' <br />- MINE I.D.: Bowie Mine Number 2. <br />-SAMPLING DATES: Between July 3 -early August. <br />- MINE LOCATION: Delta County, portions of Sections 10 and 15, T 13 S, R <br />91 W, tieing between approx. 5860' and 7200' elevation. <br />- PARAMETERS: Total vegetative cover (species diversity), herbaceous <br />production, woody stem density. <br />- SAMPLE HISTORY: No previous sampling: preliminary rare plant species <br />searches performed on May 11, 18 and 19. <br />-EXPECTED NUMBER OF COMMUNITIES: <br />- Two communities (juniper woodland, mixed shrubiand) are expected to <br />be matched to reference areas. <br />- One meadow area (upper) was estimated at approximately 5 acres in <br />size and therefore is expected to be a minor community. It will be qualitatively <br />sampled (some samples will be collected, but only to support qualitative description). <br />- Lower meadow area is probably large enough to be a major <br />community. A similar community has not been noted elsewhere in the near vicinity of <br />the proposed disturbed area. The meadow is heavily dominated by annual species and <br />will be sampled but will not be matched to a reference area. It is expected that success <br />standards will be arrived at in a way consistent with that described on page 2 of the <br />Division's Vegetation Guidelines (Guidelines for Compliance with Land Use and <br />PROPOSED METHODS <br />QUANTITATIVE SAMPLING -GENERAL: <br />- MINIMUM SAMPLE NUMBERS: Minimum: ]0 samples per community or <br />reference area per parameter. <br />- ADEQUACY, MAXIMUM SAMPLE NUMBERS: Communities and <br />reference areas will be sampled to adequacy (using two-tailed table value for n-1 <br />degrees of freedom at the 90% confidence level) or to a maximum of 50 samples for <br />each community or reference area. <br />- LOCATION: Location of sample points will be within the area that could be <br />disturbed and will contain areas that eventually will not be disturbed. The exact <br />location of the road up to the mine is not expected to finalized until after the vegetation <br />study is completed. <br />- RANDOM: Selection of sample locations will be randomized, and will involve <br />the selection of points from a gridded map. <br />- FIELD PLACEMENT: Location of sample points in the field will be with <br />compass and pacing. <br />- MAP: Approximate location of sample points will be designated on a map that <br />will be enclosed with the report. <br />Map will also show community and reference area locations. <br />TOTAL VEGETATIVE COVER: <br />- Total vegetative cover below 4' in height will be estimated using an optical <br />point frame developed by ESCO Associates. <br />- Cover transecu will originate from the sample point locations. <br />
