VF METHOD - EXAMPLEFirst, compute volume factor foreach diameter-height class using avolume table and Tree Factorcalculated in previous slide:Example: for a BAF 10 prism• TF 10 = 18.349VF = TF × viii• Volume of a 10" /2-log tree is 63 bf.- it is v iv i is determinedfrom a publishedvolume table
VF METHOD - EXAMPLE• n i the total number of trees in diameter class i• n p is the total number of points•VF i is the volume factor for diameter class in∑ i×Volume per acre=npVFiCalculate volume for each diameter-height class.
