Ecology Lab 2 - Grassland Data Set 1 - Quadrat Plant Analysis

This data was collected in the grassland outside of Saywell Woodlot on September 23rd, 2015. <br><br>Using two square-meter quadrats, our lab group collected 25 plots of data by setting 2 plots one meter off both sides of a 50 meter transect line. We set each plot exactly 2 meters from the the previous plot along the transect with a total of 13 on the left side and 12 on the right. <br><br>In each plot, we recorded plant abundance by counting each single and multistem plant exluding grass. We also recorded the total number of different species in each plot by cross examining the plot from right to left, bottom to top. Afterwards, we approximated the total vegetation coverage as well as the total grass coverage. These were recorded by examining what percentage of the plot was covered by all vegetation and which percentage was covered by grass, respectively. <br><br>All data was recorded and combined on a master copy after the last plot was collected.

本数据集采集于2015年9月23日，采集地点为赛维尔林地（Saywell Woodlot）外围的草原地带。

本研究团队采用2平方米样方（quadrats），沿一条50米样带（transect line）两侧各1米处设置采样点，共计采集25组样方数据。沿样带方向，每个采样点与前一采样点的间距严格为2米，其中样带左侧设置13个采样点，右侧设置12个。

在每个采样点内，研究人员通过计数所有非禾本科的单茎与多茎植株，记录植物多度；同时通过从右至左、由下至上遍历样方的方式，统计样方内的不同物种总数。随后，研究人员分别估算了样方的总植被盖度与禾本科植物盖度，具体通过统计样方内所有植被的覆盖占比与禾本科植物的覆盖占比完成记录。

在完成最后一个采样点的数据采集后，所有数据均被记录并整合至主数据文档中。
