Testing the Accuracy of White Spruce Total-Tree Volume Equations
Sixteen equations developed for predicting the volume of white spruce were tested for accuracy on plantation-grown trees in the upper Great Lakes region. Ten equations were found biased and six unbiased; of the six unbiased equations, only three were also precise. Precise tree volume equations can predict to within 13% to 15% of the actual volumes as estimated by stem analyses. North. J. Appl. For. 10(3): 112-116.
