Abstract

Relative density is an index of crowding for forest stands, expressed as the ratio of absolute density (number of trees or basal area per acre) to the density of a stand the same size and species composition at maximum density (eg an undisturbed stand). The measure is often used for stocking charts, but each applies to a specific forest type and often to a single species. A relative density measure for mixed-species stands is developed in which each species diameter class is multiplied by a conversion factor. Allegheny hardwoods in Pennsylvania are used as a case study. -P.J.Jarvis
