This study was conducted to analyze the ecological environment of the 53 uninhabitable islands ofJeju for the management formulation. The result of the Pearson correlation analysis were 0.647(p<0.01) forherbs, 0.585(p<0.01) for trees and 0.762 (p<0.01) for animals which means that there is a high correlationbetween the size of the forests in the uninhabitable islands and the species diversity of herbs, trees and animals. For the regression modeling to predict the forest area, the R value was 0.899 and the R2 was 0.803 with 79.7%statistical significance. This study also classified the uninhabited islands based on its forest area into two classes,with a forests area of 0.5ha and with a forest of approximately 12ha. The importance value of the biodiversityin the uninhabited islands was also evaluated using DEA and the islands with higher importance, namelyDMU14(0.941), DMU36(0.964), DMU44(1.000) and DMU45(0.903) were recommended to be managed. It wasobserved that uninhabited islands with forests had a mean importance value of 0.439 which is higher ascompared to the uninhabited islands without forests with 0.096. This verified that there is close relationshipbetween forest and biodiversity.
