Pressler's Cubic Foot Formula
A cubic foot formula for estimating tree volume. This formula suits trees whose shape approximates that of a cone or a paraboloid.
The length of the tree is taken from the point where the lower diameter is measured well above the butt swell to a point where the diameter of the log equals one half of the the lower diameter.
