The potential plant community is mainly ponderosa pine and ar <br />understory of Arizona fescue, .mountain muhly, Gambel oak, pine <br />dropseed, wheatgrass, and snowberry. The potential production of the <br />native understory vegetation in normal years is about 700 pounds of <br />air-dry vegetation par acre. <br />This soil is suitod to production of ponderosa pine. Based on a <br />sit• index of 55, the potential production per acre of merchantable <br />timber is 3,000 cubic feat from an even-aged, fully stocked stand of <br />trees 100 years old or 11,900'board feat (International rule, 1/8 in.:n <br />kerf) from an •ven-aged, fully stocked stand of trees 100 years old. <br />Opportunities exist on this unit for the limited production of <br />Christmas treas. This high value crop may be a viable economic <br />alternative to the production of sawtimber. Tha Larkson soil can <br />provide transplants of ornamental ponderosa pine. In some areas <br />~~ stones on the surface can interfere with falling, yarding, and other <br />operations involving the use of equipment. <br />Minimizing the risk of erosion is essential in harvesting timber. <br />Proper design of road drainage systems and care in the placement of <br />culverts help to control erosion. Spoil from excavations is subject <br />to rill and gully erosion and to sloughing. Minimizing the removal of <br />organic litter from the surface helps to maintain high water intake <br />rate, to reduce runoff, and to maintain an adequate source of <br />nutrients for trees. To stabilize grades, cuts and fills, and oth?r <br />disturbed areas, roads, landings, and skid trails should be provided <br />with water bars and reseeded following harvest. To provide an <br />adequate seedbed, the surface should be chiseled or otherwise <br />disturbed. Seeding late in fall helps to insure that the content of <br />~` moisture in the soil will be adequate for the establishment of <br />seedlings next spring. <br />i, <br />/4i <br />
