0 EXHIBIT 5 <br />period of optimum plant growth, when the plant cover and production were near their peak. A <br />total of 79 plant species were observed in the field sampling of the 99 cover and shrub density <br />transects sampled in this evaluation of which 26 plant species actually encountered in the field <br />sampling efforts and are presented in Table 2.04.10- 1, CAM - Colorado LLC - Unit Train <br />Loadout - Plant Species List. <br />Vegetation Mapping. Most of the different vegetation types within the proposed Unit Train <br />Loadout study area were initially delineated by using a Trimble Model Geo XH global <br />positioning system. This unit typically has a real time accuracy of plus or minus one meter and <br />once the data are post processed the accuracy of the data are typically less than one decimeter. <br />he boundaries of most of the vegetation types were delineated by walking either a line or an <br />area feature wherein the boundary of each vegetation type was delineated. For the adjacent <br />areas located within one half mile of the proposed Unit Train Loadout permit boundary, these <br />areas were mapped using the detailed aerial photography described above. The Vegetation <br />Guideline recommends that "vegetation type delineation should be based on existing, visually <br />dominant species ..." <br />Sample Adequacy. A statistical summary of all of the data collected to characterize the plant <br />cover, production, and shrub density is presented in Table 2.04.10 -2, Unit Train Loadout - <br />Sample Adequacy Calculations. This comparison documents that a sufficient number of <br />samples were collected to describe the parameters of "total plant cover" for the major plant <br />communities sampled at the 90 percent confidence interval or until the required maximum <br />number of samples had been collected, but that sample adequacy was not achieved for the <br />minor plant communities sampled. With respect to herbaceous production, as allowed in the <br />Vegetation Guideline and as directed in consultation meetings with the CDRMS, sampling for <br />herbaceous production stopped after 50 transects had been sampled. <br />Transect Locations. The field locations of all of the cover, production and shrub density <br />transect sampled in this evaluation are shown on permit application Map 3, Permit Area <br />Vegetation Map. The specific details corresponding to each vegetation community or reference <br />area sampled is discussed in connection with the discussion pertaining to each site. <br />MAJOR PREDISTURBANCE AREA VEGETATION TYPES <br />GREASEWOOD <br />This vegetation type is found adjacent to Reed Wash, the major drainage channel which bisects <br />the proposed project area. This vegetation type on the east borders the Industrial Vegetation <br />plant community and on the west borders irrigated pasture and irrigated wetlands. <br />This is the largest predisturbance plant community type found within the proposed Unit Train <br />Loadout permit area (Map 3 - Permit Area Vegetation Map) that will potentially be disturbed <br />by the construction of the proposed unit train loadout facility. The Greasewood Predisturbance <br />plant community covers an area approximately 87.32 acres in size and accounts for nearly <br />41.91 percent of the proposed unit train loadout study area. The results obtained from the <br />7 <br />
