Adult-Sapling Tree Data

The physical characteristics of 20 trees were measured on September 23, 2014 at 3:00-4:00pm in the Saywell Woodslot (York University, 43° 46' 9.228"N, 79° 30' 29.556''W). Adult Maple Trees were identified, along with the nearest sapling to the adult tree. For each adult tree, the diameter at breast height, and canopy coverage was recorded, along with the distance from the adult to the closest sapling of the same species. For each sapling, diameter at breast height was measured and recorded.

本数据集的测量工作于2014年9月23日下午3:00至4:00在塞维尔林地槽（Saywell Woodslot，约克大学，地理坐标为北纬43°46'9.228''N、西经79°30'29.556''W）开展，共对20棵树木的物理特征进行了测定。研究人员首先识别出成年槭树（Maple Trees），并同步确定了每棵成年树周边的同种近邻幼树（sapling）。针对每棵成年个体，研究人员记录了其胸径（diameter at breast height）、冠层覆盖率（canopy coverage），以及该成年树与邻近同种幼树之间的距离；针对每株幼树，研究人员亦测量并记录了其胸径。
