Differences between timber yields on small research plots and on managed forests are due mainly to differences in definition of forested area, in scale and quality control of management treatments, and in uniformity of the stands. In large areas where management has not yet made stands uniform, research results may serve only as general guides to potential growth. The manager who is practicing some degree of intensive forestry can often find research data on which to base accurate estimates of growth and yield. To apply the information, he must exclude unproductive areas from estimates of his acreage, monitor stands for damage, and supervise treatments efficiently. There is, however, no single magic number that adjust for differences in growth between research plots and larger managed forests.
