Notes: Determining Investment-Efficient Diameter Distributions for Uneven-Aged Northern Hardwoods
Abstract:The constant "q" of de Liocourt is often used to model the diameter distribution of uneven-aged forest stands and produces "balanced" size class distributions. Claims that such distributions are the most efficient for uneven-aged management or necessary to achieve sustention of production have led to the use of the concept in a variety of management models. Using a northern hardwood mixed-species growth model and a Weibull distribution function, we demonstrate that "balanced" diameter distributions are not investment-efficient and are not necessary to achieve sustention of production over a fixed cutting cycle. Results are very sensitive to per tree price and maximum tree size assumptions. For. Sci. 34(1):243-249.
