Woodlot Dataset

We as a group of four students collected a data on the grasslands and woodlot plants of the York University campus. For the woodlot experiment in a row of 10 trees, as a group of two : 1. The Diameter of Breast Height of each tree in a row of 10, were measured using a Transect tool placed horizontally at the base of the tree. Measrements were recorded in centimetres. 2.Second, the distance of the trees from its nearest sapling (same species) were measured by one person holding the one end of the Transect tape at the Tree and the other person holding the other end at its sapling. This was continued in a row from the sapling to the next tree and so on. Measurements were recorded in metres. 3.Lastly, the extent of the canopy coverage of each tree was estimated by making a square with fingers and holding it up and the visible sky was observed and an estimate was recorded. Data was recorded in percentage.

由四名学生组成的研究团队，采集了约克大学（York University）校园内草地与林地的植物相关数据。针对10棵树木排成一行的林地实验，由两人组成的子小组开展以下三项测量工作：
1. 对该行10棵树木的胸径（Diameter of Breast Height）进行测量：将样带工具（Transect tool）水平放置于树干基部，测量值以厘米为单位记录。
2. 测量每棵树木与其最近的同种幼树之间的距离：一人将样带卷尺（Transect tape）的一端固定于目标树木处，另一人将另一端固定于该幼树位置，随后沿行依次从该幼树延伸至下一棵树木，重复上述测量流程。测量值以米为单位记录。
3. 估算每棵树木的冠层覆盖度：通过双手手指搭建方形框架并举起，观察框架内可见天空的占比以完成估算，最终以百分比为单位记录数据。
