Abstract:
Equations and curves are presented for estimating height and site index of Douglas-fir(Pseudotsuga menziesii (Mirb.) Franco) on hot, dry sites in the Willamette NationalForest in western Oregon. The equations are based on the dissected stems of 27 trees.The curves differ from those previously published for Douglas-fir. Instructions arepresented for their use.
Keywords: Increment (height), site index. Douglas-fir, Oregon (Willamette NationalForest).
