It is generally recognized that normal yield table values are not directly applicable to nonnormal or average stands. Since these tables apply only to densely stocked stands in which the crowns of trees are usually touching, an adjustment must be made before they can be applied to average stands, even in the densest in which openings occur. This is generally done by comparing basal area of normal and average stands. Basal area of the average stand divided by the normal basal area gives a ratio which is the measure of stocking percentage. Normal yield table values are reduced by the actual stocking percentage thus obtained.
