Mortality data for Japanese oak wilt disease and surrounding forest compositions

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”.日本栎枯萎病（Raffaelea quercivora）是一种由栎长小蠹（Platypus quercivorus）传播的媒介传播病害，可引发日本境内壳斗科植物大规模死亡。本数据集涵盖山形县鹤冈市365个研究样地内1089株槲栎（Quercus crispula）、846株枹栎（Quercus serrata）的存活状况，以及样地周边的林分条件。研究样地的点位信息存储于"gps_points.csv"文件中，原始观测数据存储于"trees.csv"文件内。"data.csv"文件收录了基于野外实地观测数据计算得到的两类栎树个体的三类参数：1）存活状态（存活/死亡）、2）胸高断面积、3）样树周边林分的物种组成，同时包含样树周边的景观格局指数。研究区域原始植被图与简化植被图的植被类别对应关系，存储于"vegetation_maps.csv"文件中。
