The potential plan[ community on this unit is mainly western <br />wheatgrass, Indian rice grass, bottlebrush squirreltail, winterfat, and big <br />sagebrush. Bluebunch wheatgrass, needleandthread, and Douglas rabbitbrush <br />are also present in the potential plant community. The average annual <br />J production of air-dry vegetation is about 800 pounds per acre. If the range <br />I condition deteriorates, big sagebrush, rubber rabbitbrush, and cheat grass <br />increase. Management practices suitable for use on this unit are proper <br />I grazing use and a planned grazing system. <br />If [he range vegetation is seriously deteriorated, seeding is needed. <br />I For successful seeding, prepare a seedbed and drill the seed. Brush <br />management improves deteriorated areas of range that are producting more <br />woody shrubs than were present in the potential plant community. <br />If this unit is used for irrigated hay or pasture, crops, the main <br />' limitation is the hazard of erosion. Furrow, border, corrugation, and <br />I sprinkler irrigation systems are suited to this unit. Crop residue left on <br />or near the surface helps to conserve moisture, maintain [ilth, and control <br />I erosion. Proper graing practices, weed control, and fertilizer are needed <br />I to insure maximum quality of forage. If properly managed, this unit can <br />produce 3.5 tons of irrigated grass hay per acre. <br />This map unit is well suited to homesite development. Areas !n this <br />unit adjacent to hillsides are occasionally effected by runoff, which may <br />1 also be accompanied by movement of rock debris. Structures to divert runoff <br />' are needed Sf buildings and roads are constructed. <br />The map unit is in capability subclass IVe, irrigated, and IVe, <br />' nonirrigated.
