ABSTRACT

This study identified fuel characteristics of surface and crown and analyzed crown fires on Pinus densiflora and Pinus koraiensis stands in Gangwon Province in Korea. Fifteen surface fuels of each tree type were sampled and 16 trees of each species were destructively sampled to identify crown fuel characteristics. Pinus koraiensis has higher surface fuel moisture content due to the difference in crown cover, although the two types show similar crown fuel moisture content. Pinus koraiensis (34.4%) has more crown needles than Pinus densiflora (25.7%), but two species have similar combustible of available fuel, 55.8% and 55.6%, respectively. The adjusted coefficients of determination(R2 adj) values were high (more than 0.850) in all crown fuel classes. The canopy bulk density of Pinus koraiensis was 1.56 times higher than that of Pinus densiflora, whereas the available canopy bulk density of Pinus koraiensis was 1.68 times higher despite the smaller canopy volume.
