Length- and Weight-Diameter Relations of Serviceberry Twigs

Abstract

In a study of the relation between serviceberry (Amelanchier alnifolia) twig diameters and twig lengths and weights, a total of 852 twigs from 110 plants on 11 different sites was examined. Equations for the regression of length and weight on diameter were developed. Despite significant variations in regression related to site, plant size, and twig location on the plant, relatively small samples of browsed twigs were found to provide precise estimates of browse utilization.
