Uprooting resistance against wind force for coniferous plantations in soils of volcanic origin was studied. The difference in uprooting resistance among Abies sachalinensis, Picea jezoensis, and Larix kaempferi was discussed. The sample site was set in Chitose plantations in Hokkaido Japan, where typhoon 0418 caused fatal uprooting damage in 2004. An uproot resistance index—the ratio of the geometrical moment of area for uprooted root-plate to the moment susceptibility to wind force—was defined to quantify relative uprooting resistance against wind force. It was calculated from the dimensional measurements for the tree forms and root-plates of 100 uprooted sample trees after the typhoon attack. As a result, the uprooting resistance for Picea jezoensis, which was less damaged among the sample species, was estimated to be greater than those for the other two species.
