. Research for tomorrow's forests : 1983 research accomplishments. --. Forests and forestry Research United States. Thinking Small: Harvesting Systems for the Interior West Small softwood trees makes up a large part of the potentially available wood in the interior West. (Lodgepole pine alone occupies more than 12 million acres). Two kinds of small-timber stands prevail — second growth, pole- sized trees, which are usually over- stocked, and mature or overmature stagnated trees, which are grossly overstocked. Severe insect and disease infestations are widespread; many of these stands are a mixture of live and dead timber. Tne danger of catastroph- ic wildfire is on the increase in these stands. The researchers found that the most effective systems incorporated feller-bunchers, grapple skidders (or farm tractors with grapples), and whole-tree chippers, with equipment to load and transport logs and chips. The benefits are a clean logging site with no residue, utilization of all material harvested, and recovery of both logs and chips to obtain maximum Grapple skidders, whole-tree processors, and chippers are the most efficient way to harvest small timber. In both kinds of stands, management objectives—whether of timber, water, wildlife habitat, or esthetics—depend upon some sort of harvesting. An efficient harvesting system could extend the wood resource as well as improve the management and protec- tion of other resources. Knowing that the costs of harvesting and handling small stems are often the main barrier to effective utilization, researchers at the Intermountain Sta- tion field-tested and evaluated several harvesting systems that handle small trees more efficiently than conven- tional harvesting and recover a mix of products. 51.
