<br />from the weathering of the shale formations. Soils range in texture from <br /> <br />sandy loam to clay, and vary in color from light-yellowish brown to light <br /> <br />reddish-brown. Where drainage conditions are favorable, salinity and <br /> <br />alkali problems are not significant. <br /> <br />Vegetation <br /> <br />Riparian vegetation associated with canals and laterals in the study <br /> <br />area covers approximately 2,000 acres and includes mainly quack grass, <br /> <br />canary grass, goldenrod, lettuce, Jim Hill mustard, sedge, willows, and <br /> <br />Russian olive. Riparian associations beyond canals near seep areas, <br /> <br />springs, and intermittent drainages are primarily sedge and rush-grass <br /> <br />followed closely by cottonwood-buffaloberry and cottonwood associations. <br /> <br />WillOW, cottonwood-willow, Russian olive, and buffaloberry are present to <br /> <br />a lesser degree, and alder, birch-alder, and.squawbush are uncommon. <br /> <br />predominant dryland vegetation associations adjacent to the canals <br /> <br />are big sage, black sage, and shrub-grass associations. Juniper and <br /> <br />shadscale, greasewood, and saltbush associations are also present in <br /> <br />the general area. <br /> <br />Wetland Habitat <br /> <br />Seepage from some Uinta Basin area canals and laterals has created <br /> <br />wetland habitat in several'portions of the unit area. These wetlands <br /> <br />provide forage and cover for wildlife. About 2,000 acres of wetlands are <br /> <br />associated with canal.and lateral seepage along the systems presently <br /> <br />being studied. <br /> <br />""'f j'" [;1 -. <br />t;"" I.J.... j <br /> <br />Fish and Wildlife <br /> <br />While the canals have no fishery value because of intermittent <br /> <br />flows, the Duchesne, Uinta, and Green Rivers provide both cold and warm <br /> <br />9 <br />
