<br />An increase in crop production may sli~htly benefit wildlife <br />in and adjacent to the agricultural areas. Assuming that the same <br /> <br />general crops will continue to be grown, consumptive species such <br /> <br />as doves, pheasant, rabbits, quail, and waterfowl, in addition to <br /> <br />non-consumptive wildlife species, may have a small increase in food <br /> <br />supply. <br />Downstream effects of waterfowl rep,ulation will be primarily the <br /> <br /> <br />protection of wildlife and wildlife habitat from damagin~ floodflows. <br /> <br /> <br />Any possible future encroachment upon existing riparian vegetation <br /> <br /> <br />and lands by other land uses can be only speculative; however, no <br /> <br />change in land use is foreseen. <br /> <br /> <br />b. El2!!. Vegetation to be affected by project con- <br /> <br /> <br />struction and subsequent inundation will be that belonging to two <br /> <br /> <br />fairly distinct complexes or associations: the grass-shrub-cotton- <br /> <br /> <br />wood association of the valley floor and the pinon-juniper woodland <br />association (predominantly pinon pine) of the adjacent hills. It is <br />the former association that will be primarily affected by dam con- <br />struction, clearing, and inundation. Roughly 2,500 acres of vegetation <br />consisting predominantly of grasses, shrubs, and a few ~roves of cotton- <br />wood trees and willows along the river, will be cleared or inundated to <br /> <br /> <br />varying degrees and periods. Approximately 300-350 acres of woodland <br /> <br /> <br />and associated understory vegetation of shrubs and grasses will be <br /> <br /> <br />affected by construction and borrow activities and the relocations of <br />State Highway 12, the county road and the Colorado and Wyoming Railroad. <br /> <br />Most cleared vegetation will be buried. Consideration will be given to <br /> <br />IV-B <br /> <br />. <br /> <br />. <br />
