Projecting a Stand Table Through Time

Abstract

Stand tables provide number of trees per acre for each diameter class. This paper presents a general technique to predict a future stand table, based on the current stand table and future stand summary statistics such as trees and basal area per acre, and average diameter. The stand projection technique involves (a) predicting surviving trees for each class, and (b) growing tree diameters such that the stand table at the end of the growth period produces future stand summaries identical to those mentioned above. Linear and nonlinear diameter growth models produced similar results. The stand table projection approach was as good as the parameter-recovery Weibull model for unimodal distributions, and out-performed the Weibull when diameter distributions were bimodal or irregular.
