This report discusses the process of planning logging operations on steep, unstable terrain on the Queen Charlotte Islands, British Columbia. The report describes the current logging planning process, its data requirements and methods of data collection, and the results of a series of alternative logging plans prepared to minimize the potential for logging-accelerated mass wasting. Recommendations are also made for improving the planning process through the amount and quality of data required, evaluating alternative plans, and logging-system selection.

Intensive ground mapping on two watersheds provided data for the preparation of detailed logging plans. The logging plans involved various combinations of equipment, including equipment that was in common use at thetime (highlead, mobile yarding crane, and grapple), equipment that was less common (tower skyline), and equipment not yet available (helicopter).
