Description: Eucalyptus saligna trees grown in short-rotation plantations on the island of Hawaii were measured, harvested, and weighed to provide data for developing regression equations using non-destructive stand measurements. Regression analysis of the data from 190 trees in the 2.0- to 3.5-year range and 96 trees in the 4- to 6-year range related stem-only and total above-ground biomass to diameter at breast height and total height. Equations developed for each age class are recommended over equations developed for the combined data base (286 trees). For younger stands (<4-years) recommended equations include one based on diameter measurements only, thus simplifying field measurements.

Key Words: biomass equations, prediction equations, short rotation silviculture, Hawaii, Eucalyptus saligna
