Description: A method is presented for estimating above-ground herbaceous and woody biomass on competition research plots. On a set of destructively-sampled plots, an ocular estimate of biomass by vegetative component is first made, after which vegetation is clipped, dried, and weighed. Linear regressions are then calculated for each component between estimated and actual weights and are used to adjust ocular estimates of biomass on permanent or temporary plots. In trials, R2's ranged from 0.57 to 1.00. Training hints and calculation procedures are outlined.
