註釋

Trees were measured in 58 tenth-acre plots for the purpose of appraising growth and yield of Interior Alaska stands. All trees six or more feet tall were tallied by species, diameter, and height classes. Trees measured include white spruce, black spruce, paper birch, quaking aspen, and balsam poplar.
