ABSTRACT

The objective of this study was to develop an allometric equation to estimate crown fuel load of Pinus rigira in South Korea. Twenty representative trees were cut down for samples, and crown fuel were classified according toits component(needle or branch), life (alive or dead), and diameter(<0.5cm, 0.5-1cm, 1-2cm, 2-4cm, >4cm). A fuel load allometric equation was developed with diameter at breast height(DBH) and tree height as independent variables. The result of this study showed that the > 4cm branches recorded the largest fuel load (9.521kg), followed by needles fuel (8.852kg), live branches with size ranging from 2 to 4cm (7.226kg), 1-2cm (3.920kg), <0.5cm (2.890kg), 0.5-1cm (2.711kg) and dead branches (1.387kg) as the lowest. On average, the adjusted coefficient of determination was high (R2adj = 0.9870-0.8596) and standard error of estimate was high (S.E.E. = 0.1670-0.6859) in allometric equation,lnWt=β0+β1 lnD. However, the differences in R2adj and S.E.E. between the equations were not significant.
