To insure consistency of application of the Heavy Cutting Legislation the following silvicultural guidelines and forestry standards are established. If no stocking guide is available, the residual stand basal area will not be less than 40 square feet of acceptable growing stock per acre.
Acceptable species is defined as a potential crop tree to be retained and managed.
Acceptable growing stock means a stem having a diameter of 4.5 inches or greater at breast height which has the potential of producing a sawlog product of a commercial species of any grade, now or in the future.
