A five parameter submodel predicted as well as an eight parameter model proposed by Kozak, 1988. Taper variation was explored between two geographic regions from which trees with different taper were suspected. Results showed that different site classes, not fully accounted for in the model, might have an effect on the prediction of taper in each region. Also, the effect of crown class and live crown ratio on prediction was evaluated. The model selected exhibited different prediction patterns for dominant and suppressed trees. On the other hand, live crown ratio did not appear to affect prediction. A computer program was written to use the taper equation developed to compute total and merchantable volume to different top diameter limits.ix, 83 leavesBTDapplication/pdfIn CopyrightLD5655.V855 1988.R432Forests and forestry -- MeasurementPinus oocarpaThesishttp://scholar.lib.vt.edu/theses/available/etd-11202012-040026/
