Abstract:

Competition indices, based on the distance weighted ratio of competitor and subject tree sizes, were correlated with annual diameter and height growth. Correlations with growth were greater when competitors were chosen by angle gauge techniques than by a fixed competition radius. Some of the tested indices were as highly correlated with tree growth as the complex area overlap and weighted area overlap competition indices used in the past. Correlation with growth and computational ease indicate that simple competition indices may be well suited to tree growth simulation and field applications. Forest Sci. 22:454-456.
