Environmentally sound timber extracting techniques for small tree harvesting

Abstract

Due to large area disturbed and great deal of energy cost during skidding operations, introducing or applying the appropriate techniques of timber extracting could significantly reduce the impact of timber extraction operations to forest environment while pursuing the reasonable operation costs. Four environmentally sound timber extraction techniques for small tree harvesting, particularly for thinning operations, were presented and introduced in this paper. The results of evaluation, test or practices indicated that these timber-extracting techniques are feasible, applicable and reasonable in small tree harvesting with a relatively low impact no environment and a moderate operation cost.
