Declining old‐forest species as a legacy of large trees lost (2018, background): “Quadratic mean diameter (QMD) is a commonly used metric in forestry that more strongly reflects the influence of large trees on stand tree size classifications than arithmetic mean (Curtis & Marshall, 2000).”
Forest Growth and Yield Modeling (2011, background): “There are several practical and historical reasons why QMD has been preferred over the simple arithmetic mean (Curtis and Marshall, 2000).”
A comparison of alternative methods for estimating the self-thinning boundary line (2005, unknown): “…is a direct measurement of average tree size in forest inventory, (2) there is an exact relationship between D, N, and stand total basal area, and (3) we avoid introducing biases into the analysis caused by computing tree volume from a specific volume equation or table (Curtis and Marshall 2000).”
