Regeneration

Count of all seedling and saplings tree species that were under 2 inches in DBH. Counts were done on each of the 10 sampling plots at each site. A 5 m^2 PVC square was placed on the perimeter of each plot and all seedlings whose stems originated in the square were counted. Seedlings were only counted if they had true leaves (More than just cotyledons).本数据集统计了胸径（Diameter at Breast Height, DBH）小于2英寸的所有树种幼苗与幼树的总数量。计数工作在每个样地的10个采样样方中分别完成。具体操作流程为：将一块面积为5 m²的聚氯乙烯（PVC）正方形框架放置于每个采样样方的周边区域，统计所有茎干起源于该框架范围内的幼苗；且仅统计具有真叶（不止子叶）的幼苗个体。
