• i <br />' Permeab.il.ity of the 18rgert soil .is moderately rapid. Available water <br />capacity is very low. Effective rooting depth is 10 to 20 inches. Runoff <br />is merj.iun to rapid, and the hazard of water erosion .is moderate to high. <br />'This unit .is used for livestock yraz.ing. <br />'the potential plant community on the Troutdale soil .is mainly <br />needle~andthread, blue grams, and western wlieatgrass. Average annual <br />pr_oduc:tion of air-dry vegetation is about 800 pounds per acre. If the <br />cond.it.ion of the range deteriorates, sleepygrass, blue grams, brown <br />snakeaeed, and fringed sagebrush increase.
