註釋This study was initiated to examine alternatives to Plonski's tables and Forest Resource Inventory for growth and yield prediction by using the recently developed Forest Ecosystem Classification (FEC) and the extensive database of the Spruce Falls Power and Paper Co. Ltd., which has been collecting data from permanent sample plots on their limits since the 1930s. The study addressed the needs of forest level planning by grouping the 14 operational groups of the FEC system into three or four classes of similar productivity for forest level forecasting and evaluating the usefulness of the FEC system for forest productivity studies; by constructing density class yield curves and tables based on these productivity classes; by constructing yield curves based on the percentage of black spruce in the stands within each productivity class; by developing individual-tree local volume tables for black spruce; and by developing a site treatment matrix to help identify gaps in the database in terms of operational groups and treatments.
