A Generalized Height-Diameter Equation for Coastal California Species
Abstract:The equation H = Hm exp [-b(D-c - Dm-c)] is proposed for estimating the total height of trees on growth and inventory plots. This estimator requires only the computation of average dbh (Dm) and average total height (Hm) of a sample of trees selected from the upper one-fifth of the stand diameter distribution. The procedure is also efficient because this stand component is also used to estimate site index. With small samples, these equations were found to be accurate in local volume table construction. Results are illustrated using redwood (Sequoia sempervirens) and Douglas-fir (Pseudotsuga menziesii) data from northern California. West. J. Appl. For. 3(4):113-115, October 1988.

More about this publication?
- Each regional journal of applied forestry focuses on research, practice, and techniques targeted to foresters and allied professionals in specific regions of the United States and Canada. The Western Journal of Applied Forestry covers the western United States, including Alaska, and western Canada; WJAF will also consider manuscripts reporting research in northern Mexico that has potential application in the southwestern United States.
