Abstract

Plonski's yield tables have been used extensively in forest man- agement, economic evaluation, and as a basis for management plan- ning in Ontario. However, because these tables are based on site classes, they are not directly applicable to uneven-aged mixed- wood cover types. A four-parameter nonlinear model was employed to express various stand attributes as a function of stand age and recently developed basal area indices for the major species in Ontario. The resulting variable stockingyield functions will be applicable to even-aged stands as well as the boreal mixedwood. Basal area index proved superior to site index for esti- mating both merchantable basal area and volume for the James RiverJMarathon data set representing boreal mixed from Northcentral Ontario. In addition, stand basal area index may be determined easily and inexpensively via horizontal point sampling or prism cruising.
