represents) for plot trees by taking the denominator of the plot size (e.g. 20 for a 1/20th acre plot) and dividing by the number of plots. For each plot tree, determine the basal area (in square feet) by multiplying the DBH (in inches) by itself (i.e. square it) and then multiplying by 0.005454: Tree BA = .005454 x DBH2 2. Multiply the basal area for each tree by the expansion factor to determine the basal area per acre represented by each tree.
