Abstract

The damage occasioned by harvesting in a planned manner is assessed. The main features of the approach to damage reduction were: previous surveying and careful construction of roads and skidding trails, climber cutting and directional felling. Harvested volume was 20m3 ha-1. The number of damaged trees over 10cm diameter was 5.3 pper tree logged and the volume of damage was 0.27m3 per cubic meter extracted. Damage caused to the canopy by road and trail cutting, provision of landings and felling damage amounted to a maximum canopy opening of 15%.
