Abstract

Density management diagrams (DMD) of the type pioneered by Japanese foresters (Ando 1968) were introduced to North American forestry when Drew and Flewelling (1979) published a diagram for coast Douglas-fir (Pseudotsuga menziesii var. menziesii). DMDs are essentially models of stand average dimensional relationships. Foresters have used simple two-parameter stocking guides for years (Reineke 1933, Gingrich 1967, Wilson 1979), but the inclusion of additional size parameters, particularly height, greatly improves the utility of these charts.
