Abstract:

Better understanding of the nation's forest situation requires an appraisal of present stand in relation to the volume of growing stock' needed to sustain prospective timber requirements. This paper points out that for a given level of output the required growing stock is a function of cutting age and may be expressed as a multiple of the yield. Growing-stock ratios, deduced from available yield tables and assumptions as to average cutting ages, indicate that the poorly distributed volume of timber we now have is not greater than the well-distributed volume of growing stock we shall need in order to maintain the current level of output, to say nothing of attaining a larger potential yield. Contrary to popular opinion, the author's calculations indicate that the growing stock deficit in the East is most serious in southern pine.
