Predictions of annual diameter (ΔDBH, cm∙yr–1), height increment (ΔHT, m∙yr–1), and annual probability of survival across diameter at breast height (DBH, cm) for different species using Eqs. [3], [4], and [5] respectively. For all equations, basal area in larger trees, total basal area, crown ratio, and climate site index were fixed at 10 m2∙ha–1, 25 m2∙ha–1, 0.33, and 17 m, respectively. For height increment, total height (HT, m) was varied as fixed percentage of the DBH (HT = DBH × 0.6). Species are American beech (AB), balsam fir (BF), eastern hemlock (EH), red maple (RM), sugar maple (SM), spruce (SP), white pine (WP), and yellow birch (YB)
