This unit is used for livestock grazing and wildlife habitat. <br /> The potential plant community on the Clapper soil is mainly Utah <br /> % <br /> juniper and an understory of bluebunch wheatgrass , gal leta , 4CL �4167 <br /> bottlebrush squirreltail , and Wyoming big sagebrush . If range 7 <br /> condition declines due to overgrazing, the proportion of forbs, <br /> shrubs , and juniper increase . The potential production of the native <br /> understory vegetation in normal years is about 350 pounds of air-dry <br /> vegetation per acre . Management practices suitable for use on this <br /> unit are proper grazing use , deferred grazing , and planned grazing <br /> system. <br /> This unit is suited to production of pinyon pine and juniper. The <br /> site index for pinyon-juniper ranges from 40 to 50. Based on a site <br /> index of 44 for pinyon-juniper, this site will produce less than 3.8 <br /> cubic feet-of wood per acre per year. The main concerns in producing <br /> • and harvesting timber are complex slopes, content of coarse fragments , <br /> low water holding capacity , rapid runoff , and high erosion hazard. <br /> Stones on the surface can interfere with felling , yarding , and other ` <br /> operations involving the use of equipment. Leaving high juniper <br /> stumps with several small live branches promotes the growth of post <br /> crops . <br /> Clapper soil is poor, —� reconstruction material for drastically <br /> disturbed areas large stones throughout the profile . <br /> This map unit is in capability subclass VIIe . It is in Foothill <br /> Juniper site #447 . <br /> Tentative - subject to rcvts:cn <br /> 4.4" <br />
