What does the diameter distribution of a forest stand tell the forester? The author has analyzed diameter distributions for some stands containing white pine in Pennsylvania; old white pine stumps from virgin stands logged in the past were also studied. He concludes that an all-species stand graph for mixed stands reveals little as to the age of the stand; that the graph for even-aged white pine resemblea the Gauss curve of normal frequency even in stands which are neither fully stocked nor pure; and that stump diameter distributions of virgin stands of white pine strongly suggest evenness of age and catastrophic origin of this species.
