Tree height is measured either (1) on a size-stratified sample of trees (e.g., Bohlman & O’Brien, 2006) or (2) on the largestdiameter individuals in the plot for the purpose of estimating maximum tree height (Wright et al., 2010). Methods for measuring tree height are described in the protocol below and in Larjavaara & Muller-Landau (2013); the ForestGEO standard is to use what Larjavaara & Muller-Landau refer to as the sine method.
