The M-w diagram for various types of forest stands can be approximated by a few segmental linear relationships between M and w. Each segment is related to the story (stratum) with the specific characteristics of the beta-type distribution function. And this function reflects some aspect of the modes of packing trees in a three dimensional space as realized eventually by the real forest stand. The number of stories distinguished by the M-w diagram ranges from four to one as related to the climatic conditions under which the forest stands grow.
