Japanese oak wilt (Raffaelea quercivora) is a vector-borne disease transmitted by the flying ambrosia beetle, Platypus quercivorus, and causes mass mortality in the fagaceous species of Japan. The data include the mortality status of 1089 Quercus crispula and 846 Quercus serrata trees and surrounding forest conditions in 365 study plots in Tsuruoka city, Yamagata prefecture. Locations of study plots are shown in “gps_points.csv” and raw observation data are shown in “trees.csv”. 1) viability status (dead/alive), 2) basal area, and 3) species compositions of stands around the tree for individuals of Q. crispula and Q. serrata in “data.csv” were calculated using field observed data. Landscape metrics around the tree are also shown in “data.csv”. Correspondence between vegetation class of original vegetation maps and that of a simplified vegetation map of the study region is shown in “vegetation_maps.csv”.
