<br />The native vegetation in most places consists of Indian ricegrass, <br />western wheatgrass, needleandthread, blue grams, pinyon pine, Rocky Mountain <br />Juniper, mountain mahogany, Gambel oak, bitterbrush, serviceberry, and big <br />sagebrush. Proper grazing use coupled with planned grazing systems are the <br />most important practices to maintain quality and quantity of rangeland <br />vegetation. Range seeding along with deferment will speed up revegetation <br />of areas depleted by heavy grazing, and other disturbances. Seeding must be <br />done by hand broadcasCing or aerial seeding. Revegetation is important on <br />these areas because of the highly erosive nature of this soil. Combinations <br />of stockwater development, fencing, and deferred grazing will help improve <br />grazing distribution and maintain range condition. <br />The Zyme soil is suited to the production of pinyon and juniper. <br />Woodland products such as firewood, fence posts, Christmas trees, and pinyon <br />nuts can be obtained from this soil. It is capable of producing about 10 <br />cords of firewood per acre in a stand that averages five inches in diameter <br />at a heighth of one foot, when all limbs larger than two inches in diameter <br />are used. The main limitations for woodland production are shallow depth to <br />bedrock, low available water capacity, steep slopes, Rock outcrop, and high <br />erosion hazard. <br />Limiting soil disturbance when harvesting trees will help minimize soil <br />erosion. Reseeding to adapted grasses may be necessary in some areas after <br />harvesting trees. Low precipitation and brushy plants may influence <br />seedling survival. Areas can be maintained in pinyon and juniper by <br />selective cutting, leaving small trees and a few larger seed producing <br />trees, and controlling livestock grazing so that seedling trees may get <br />r- established. <br />
