6.4.10 EXHIBIT 7—Vegetation Information <br /> (1) After discussing the site with Ms. Amanda James, biologist, with the Montrose office <br /> of the FPAC-NRCS, she provided seeding recommendations in a letter enclosed herein. <br /> The following information about existing site vegetation was developed in those <br /> communications: <br /> (a) The site is presently covered approximately 30% by a sparse understory of <br /> native grasses, cacti and forbs. The remaining 70% of the parcel is covered by <br /> irrigated crops or pasture. The area has historically been used for general <br /> irrigated agriculture and is covered by 0 to 6 inches of organically poor, silty- <br /> sandy topsoil. The maximum height of cottonwood trees near the central <br /> drainage are approximately 30 feet. <br /> (b) The Pre-Mining Exhibit (sheet Cl), in Appendix C, details the relationship <br /> between the various existing land uses for the 120-acre Thompson Pit parcel. <br /> (c) As indicated in Exhibit I— Soils Information, the Thompson Pit site is considered <br /> non-productive unless irrigated and has no capacity for hay meadows or <br /> cropland. The area may be used for range land once it is revegetated per the <br /> recommendations of the NRCS. Due to the scarcity of native grass species and <br /> forbs, it would not support a significant number of cattle for grazing purposes. <br /> (2) The Pre-Mining Exhibit Map (C1) details the existing types of soils and their <br /> respective vegetative cover on a topographic map of the quarry site. Amando James of <br /> the Montrose office of the FPAC-NRCS was consulted about the project site and its soil <br /> and vegetation cover. <br /> Thompson Pit <br /> Exhibit J <br />
