Abstract

Growth intercept models relate early average height growth of trees (the growth intercept) to site index (top height at breast-height-age 50). Typically, the growth intercept is the average height-growth during the first five growing seasons after the tree has reached breast height. This report presents a variable-growth intercept model that is based on the average height growth above breast-height for any number of years from 1 to 30. This model is more flexible than growth intercept models that use a fixed-growth period such as five years. The variable-growth intercept model has many advantages and few disadvantages over the traditional fixed growth intercept models.
