Forestry and Coal Mining (Classic Reprint) Paperback -

Until within comparatively recent years the prevailing practice in the lumber industry has been to organize an operation on a period basis; to con struct a plant of a capacity to utilize the amount of timber within a specified period of years; and to finance the operation so that when the last tree is cut the total investment will be liquidated. The plant, then, and the cut-over land have only a sal vage value. The land often must be abandoned. A Sustained Yield plan of operation recognizes the fact that timber grows; that with proper care in logging and protection the land will continuously produce successive new crops of timber indefinitely. The investment, then, in plant and land becomes permanent; it does not have to be written off at the end of a specified term of years; both plant and land continue to be productive and valuable.

The forestry department of the Corporation is operated on a Sustained Yield basis.
