Comments: (Compendium of Canadian Forestry Statistics. 1996.): "AAC prior to 1995 is determined on varying levels of net operable volume levels matched to the current industrial level of utilization."; and "1995 AAC is determined on net merchantable level of utilization which reflects the latest product technology's ability to make the most complete use of harvestable timber." Bottom line; despite there being less forest available to cut (i.e., merchantable volume decreases), the AAC increases due in part (likely principally) to assuming that industry will use much smaller trees and cut in extremely low volume stands and use logs with significant rot. This is not proven, even for LP (there is some data to refute this assumption),   and is unrealistic for other present industry (e.g., Tolko).
