Volume Estimation from Sample Tree Counts with Certain Individual Tree Volume Equations
Abstract:Since rapid inventories of forester areas are often required, it is desirable to reduce tree measurements for volume estimation when individual tree volume equations of certain commonly used types are available. In some cases it is possible to do so by altering the usual horizontal point sampling procedure so that sample trees are chosen with probability exactly proportional to the equations being used to obtain individual tree volume. In certain other cases, estimators are presented that combine counts of fixed-size and variable-size plots. One of the methods is compatible with local volume equations used in the Turnbull-Hoyer tarif system. For. Sci. 34(3):677-697.
