An Approach to Plot Sampling for Canopy Volume in Shrub Communities

A method of plot sampling for canopy volume of shrubs in plant communities is described. The method requires a three dimensional plot and an estimation of canopy volume by classes for each species in the plot. Midpoint values for the volume classes are used to calculate averages from an appropriate sample size. The method eliminates the necessity of measuring height and canopy diameters of individual species and provides an acceptable index to species dominace in the vegetation.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
