Subsampling Trees for Biomass, Volume, or Mineral Content

Abstract

Abstract A procedure for estimating aboveground biomass, woody volume, or mineral content of a tree uses randomized branch sampling and importance sampling, a technique of Monte Carlo integration. Both techniques involve sampling with selection probabilities proportional to estimated size and produce unbiased estimates of tree components and their variances. The results of a field test of the procedure for the estimation of fresh weight are presented. Forest Sci. 30: 673-681.
