Enviromentally Sound Timber Extracting Techniques for Small Tree Harvesting

Abstract

Due to large area disturbed and great deal of energy cost during-its operations, introducing or applying the appropriate timber extracting techniques 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. These techniques included animal skidding and animal-machine, single circulating cable yarding system, small farming tractor, and mini forwarder. 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 to environment and a moderate operation cost.
