<br />Most of the acreage is woodland. Part of it is used for

<br />and of wood crops..
<br />The potential native vegetation is dominantly lodge-
<br />pole pine and a sparse understory of grasses, shrubs,
<br />and forbs.
<br />Leadville soils are suited to lodgepole pine. It pro-
<br />duces about 25 to 35 cubic feet of wood per acre per
<br />year. Thinning the stand provides poles for fences, cor-
<br />rals, and power lines. Care is needed to prevent erosion
<br />of skid trails and access roads. The low water holding
<br />Capacity limits seedling survival.
<br />This soil provides habitat Tor woodland wildlife, such
<br />as blue grouse, snowshoe hare, and black bear. It also
<br />provides summer range for mule deer and elk. Managing
<br />livestock grazing and timber improves habitat for the big
<br />game summer range.
<br />Large stones and steep slopes. are the soil properties
<br />most limiting to community development. Road design
<br />should provide drainage outlets for surface runoff.

<br />tans at elevations of 7,500 to 8,500 feet. It formed in
<br />local alluvium from sedimentary rock. The average
<br />annual precipitati<iri is about 14 to 16 inches, the aver-

<br />J Small areas of Harsha loam, Roxal loam, Lymanson

<br />a; Typically the Leavitt soil has a grayish brown loam
<br />surface layer about 6 inches thick. The subsoil is brown
<br />clay foam about 28 incites tnicl;. The substratum is pale

<br />1 Most of the acreage is rangeland. Part of it is used for
<br />recreation and wildlife. A smell acreage is irrigated and
<br />~ used for hay. The cold climate and short growing season
<br />limit the production of introduced grasses and preclude
<br />r the use of this soil as cropland.
<br />Wheatgrass, muttongrass, Idaho fescue, and big sago-
<br />'.brush are dominant in rangeland vegetation.
<br />Grazing no more than 50 percent of the key species,
<br />by weight of the current season production, will maintain
<br />the condition of this site. If shrubs have become dorrri-
