Abstract:

Expressions for alternative relative measures of stand density were derived for Douglas-fir, and numerical values of alternative measures were compared for three sets of data. A simple sum of diameters to a suitable power, without reference to other stand characteristics, provided the simplest of the several diameter-based measures of stand density. The basis for this measure and relationships between this and alternative generally accepted measures are discussed. Forest Sci. 17:146-159.
