Abstract
The objective of this study was to understand the relationships between forest vegetation characteristics and the damage of Oak wilt disease. Field surveys were carried out for two groups. One group(Group A) consists of Oak wilt infected 18 sites from 7 provinces, and the other group(Group B) consists of 5 permanent sites where data on the relative density of entrance holes drilled by Platypus koryoensis., the vector of Oak wilt disease, were available. Survey results showed that 17 of 18 sites were dominated by Quercus spp.(Group A) and also showed a significant positive relationship($R^2=0.89$, P<0.05) between the relative density of entrance holes and the relative density of Quercus spp.(Group B) implying that the susceptibility to Oak wilt disease is related with the high dominance of Quecus spp. in a forest stand.
