Reforestation must be carefully managed to reduce <br />competition from undesirable understory plants. Plant competition delays <br />natural regeneration but does no[ prevent the eventual development of a <br />fully stocked, normal stand of trees. Planting nursery stock will speed <br />up reforestation. Among the trees that are suitable for planting are <br />Ponderosa pine and Lodgepole pine. Surface stones may interfere with <br />logging operations in many places. Proper design of road drainage systems <br />and care in the placement of culverts help to control erosion. Spoil from <br />excavations is subject to rill and gully erosion and to sloughing. Roads <br />and landings can be protected from erosion by constructing diversions and <br />by seeding cuts and fills. <br />• The potential plant community on this unit is mainly Ponderosa pine, <br />Arizona fescue, and western wheatgrass. Other important plants that charac- <br />terize this unit are aspen, junegrass, mountain hrome, wild ruse, hlut•grass, <br />mountain mahogany, Gambel oak, serviceberry, snowberry, and strawberry. <br />Logged areas and many forested areas are used for grazing. Proper <br />grazing use in conjunction with a planned grazing system arc important prnc- <br />rites to insure desired quality and quantity of native vegetation. Grazing <br />should be delayed until the soil is firm and the more desirable f~~ragc• <br />plants have achieved sufficient growth to withstand grazing pressure. De- <br />ferred grazing speeds up revegetation and improves range areas in poor <br />condition. Stockwater development and fencing can improve the distribution <br />of livestock and the production of understory plants. <br /> <br />
