r~ <br /> <br />from an even-aged, fully stocked stand of trees 100 years old. The main <br />concerns in producing and harvesting timber are road construction to avoid <br />areas of rock outcrop, reforestation, and prevention of water erosion along <br />roads and other areas where vegetation has been removed. Tree harvesting <br />may be restricted during periods of high snow accumulation, snow melt, or <br />High rainfall. Reforestation must be carefully managed to reduce competition <br />from undesirable understory plants. Plant competition delays natural regenera- <br />tion but does not prevent the eventual development of a fully stocked, normal <br />stand of trees. Planting nursery stock will speed up reforestation. Among <br />[he trees that are suitable for planting are Douglas Fir, Engelmann spruce <br />and Lodgepole pine. Careful consideration of road systems will avoid areas <br />of rock outcrop. Proper design of road drainage systems and care in the <br />placement of culverts help to control erosion. Roads and landings can be <br />protected from erosion by constructing diversions and by seeding cuts and <br />fills. <br />The native vegetation on this unit is mainly Ponderosa pine, Gambol <br />oak, mountain mahogany, and junegrass. Other important plants that charac[er- <br />ize this unit are Arizona fescue, mountain brome, mountain muhly, serviceberry, <br />snowberry, wild rose, bluegrass, Oregon grape, Ferns, wild celery, and straw- <br />berry. <br />Logged areas and many forested areas are used for grazing. Proper <br />grazing use in conjunction with a planned grazing system are important <br />practices to insure desired quality and quantity of native vegetation. <br />Grazing should be delayed until the soil is firm and the desirable forage <br />plants have achieved sufficient growth to withstand grazing pressure. De- <br />ferred grazing speeds up revegetation and improves range areas in poor <br />
