Field Training with Plants-Woodlot Dataset 4

Samples were taken from a woodlot at York University's Keele campus. The woodlot was not very dense, however there were a wide variety of trees. Different species of trees were identified. In total 10 samples were taken, composed of mature trees and saplings of the same species. Diameter at breast height was measured for each sample. As well as the canopy coverage, which was measured as high for full coverage and low for less coverage. The distance of the saplings with respect to their mature counterparts were measured, using transect measuring tapes, for each set of trees. Data was collected on September 21, 2016 the weather was 27°C and sunny.

本次研究的样本采集自约克大学（York University）基尔校区（Keele campus）的一片小片林地。该林地林木密度并不高，但树木种类丰富多样。研究人员已对所有树木的物种进行了鉴定。本次共采集10份样本，每份样本由同一物种的成熟林木与幼树组成。为每份样本测定了胸径（Diameter at breast height），同时测定林冠覆盖度：以“高”代表完全覆盖，“低”代表覆盖度较低。针对每组树木，使用样带卷尺（transect measuring tapes）测定了幼树与其对应成熟林木之间的距离。数据采集于2016年9月21日，当日天气晴朗，气温为27℃。
