The Forest Engineering Research Institute of Canada (FERIC) took part in the Ecosystem Management by Emulating Natural Disturbance (EMEND) multi-disciplinary research project. FERIC's part of the project was to conduct a cost and productivity study in the harvesting treatment component, which encompassed four stand types and six retention levels. This report describes the harvesting operations; presents the productivities and costs of the felling, skidding, and processing phases; and describes factors affecting the harvesting activities.
