Permeability of the Progresso soil is moderate. Available water <br />capacity is moderate. Effective rooting depth ~s 20 to 40 inches. <br />Runoff is medium, and the hazard of water erosion is high. <br />This unit is used manly for wildlife habitat and for limited <br />livestock grazing. <br />This unit provides wildlife habitat for deer, elk, hawks, and <br />eagles. <br />The potential plant community on the Pinon soil is mainly pinyon <br />pine and Utah juniper, with an understory of Indian ricegrass, <br />muttongrass, and Salina wildrye. The average annual production of <br />air-dry understory vegetation is about 100 to 500 pounds per acre. <br />If the condition of the understory deteriorates, Fendler threeawn, <br />hairy goldaster, broom snakeweed, and pricklypear cactus increase. <br />Where the understory ~s in poor condition, these plants are dominant. <br />Removal of pinyon and juniper increases the production of <br />understory forage. Management of the pinyon-juniper and range <br />resources in conjunction can lead to the improvement of all resourc?s. <br />On slopes suited to logging and range seeding with deteriorated sites, <br />benefits can be received from the sale of wood products and improved <br />grazing, when proper grazing management is applied. Range seeding <br />should be done in conjunction with removal of the overstory. This <br />would improve the understory while providing firewood and posts. <br />this soil is capable of producing 7 to 9 cords per acre in a stand <br />which will average 5 inches in diameter at a height of 1 foot. Ypung <br />pinyon pine are desirable as Christmas trees. The main limiting soil <br />feature is the high hazard of erasion. <br />The potential plant community on the Progresso soil is mainly <br />galleta, Indian ricegrass, needleandthread, and Wyoming big sagebrush. <br />fhe average annual production of air-dry vegetation is about 1,100 <br />pounds per acre. <br />3o r <br />
