Field Training with Plants- Lab #2

The members who collected this data together were Adilah Ismail, Harshvir Hehar, Amrutha Balamurugan and Olivia Kazmierczak. The study sight was a grass land on campus with great sunlight and few clouds. The area had a couple of threes that were avoided to make sure direct sunlight was used for the data. To completely collect all the data for this experiment the group was given 40 minutes. A quadrant made by connecting meter sticks together to create a square was used 20 times to collect data of 20 random spots in the grass land and were analyzed by observation. The data collected for all 20 quadrants was the abundance (the amount of vegetation within each quadrant), the amount of different types of vegetation, as well as the amount of space the grass takes up within each quadrant and the grass with the other types of vegetation in percentages. All of this data is estimated through observation. The reasoning behind collecting this data is to understand how to take data outside of the field as well as see that in a grass land not ever 1mx1m part of it will be identical in its vegetation, also certain plan species do not thrive in every part of the grass land but only in certain areas.

参与本次数据联合采集的人员为Adilah Ismail、Harshvir Hehar、Amrutha Balamurugan与Olivia Kazmierczak。本次研究的地点为校园内一片光照充足、云量稀少的草地。该区域内生长有若干树木，为确保数据采集仅利用直射日光，团队避开了这些树木所在的区域。为完成本实验的全部数据采集工作，团队被分配了40分钟的采集时长。团队使用由米尺拼接而成的正方形样方(quadrant)，在该草地中随机选取20个点位完成了20次数据采集，并通过实地观测开展数据分析。本次采集的20个样方的相关数据包括：每个样方内的植被丰度（即样方内的植被总量）、不同植被类型的数量，以及样方内草地所占空间比例，还有草地与其他植被的占比情况。所有数据均通过目测估算获得。本次数据采集的研究目的在于，一是掌握野外实地数据采集的操作方法，二是验证并非每一块1m×1m的草地区域的植被分布都完全一致，同时部分植物物种仅能在草地的特定区域存活，而非遍布整片草地。
