Stem and branch sizes of Ubame oak (Quercus phillyraeoides) in Muroto region, Kochi Prefecture, Japan.

Individual ID: Individual identifiers from A to I.
DBH: Diameter at 1.3 m height calculated with the area of tree cooky (with bark, just after cut) measured using a CCD image scanner.
Tree height: The longest path length from the root to the branch top using a tape measure aligned with stems.
Branch ID: Stem and branch identifiers of each individual (start-end). "Root" denotes the root of each tree. "End" denotes the ends of branches. The numbers following "End" indicates that there were plural branches. 
Length: Branch length measured at 1 cm resolution using a tape measure aligned with stems.
Root diameter: Diameter of the root side of each branch measured using tape measures at 0.1 cm resolution. Several thin branches of A and B were measured using a caliper at 0.01 cm resolution.
End diameter: Diameter of the top side of each branch measured by the same method with root diameters.
Note: Branches with root diameters larger than 1.5 cm (for A and B: 1.0 cm) were measured. Each tree had numerous thinner branches but not measured.
Survey date: 29 Sep 2021 - 15 Oct 2021.

个体标识符：A至I的个体标识符。
胸径：通过CCD图像扫描仪测量的树干截面积（去皮，切割后）计算得出的1.3米高度处的直径。
树高：使用与树干对齐的卷尺测量的从树根到枝顶的最长路径长度。
枝条标识符：每个个体的茎和枝条标识符（起始-结束）。'根'表示每棵树的根部。'结束'表示枝条的末端。'结束'后的数字表示存在多个枝条。
长度：使用与树干对齐的卷尺以1厘米的分辨率测量的枝条长度。
根直径：使用0.1厘米分辨率的卷尺测量的每个枝条根侧的直径。A和B的几根细枝条使用卡尺以0.01厘米的分辨率进行测量。
末端直径：使用相同的方法测量的每个枝条顶部侧面的直径，与根直径的测量方法相同。
备注：直径大于1.5厘米的枝条（对于A和B为1.0厘米）进行了测量。每棵树都有许多较细的枝条，但未进行测量。
调查日期：2021年9月29日至10月15日。
坐标区域：北纬33°19'05''至北纬33°19'14''，东经134°07'13''至东经134°07'21''。
