Management Without Rotation

Abstract The concept of rotation is of fundamental importance in the management of even-aged forests. It has in the past been used with various modifications for the regulation of uneven-aged forests. These adaptations have never been very satisfactory or successful, and they have often beclouded the practical purpose of regulation in such stands. This purpose, which is to secure and maintain an adequate balanced growing stock capable of producing a sustained annual or periodic yield, can be achieved as well, if not better, without the use of rotation. Disregarding rotation, however, calls for a direct appraisal of the desired normal structure of the forest. This article discusses the problems involved in the appraisal of normal growing stock, the determination of yield, and the establishment of the cutting plan for uneven-aged forests.
