Biodiversity of species on the grassland of Stong Pond, York University.

On September 21, 2015 in between 2:30pm to 5:30pm with a temperature of about 19 degrees Celsius, our group members conducted an experiment on the biodiversity of species. In this experiment, a dataset was collected for 25 quadrats on the grasslands of Stong Pond, York University- Keele Campus. During the study, the quadrat was placed randomly on the grassland twenty five times as replicates and was continuous. Plant species were identified in the quadrat with the help of a plant guide and features such as color, leave shape/size were also observed in the identification process. Various species of grasses were present and all were counted as one species. Common species found were: Common Milkweed, Birdfoot Trefoil, Grass, Heath Aster, Late Purple Aster, Common Thistle, Queen Anne’s Lace, Canadian Goldenrod, and Cow Vetch. The species type, total number of species observed and the total plant abundance was recorded. The data obtained was based on our visual observations, and no other tools besides the quadrat were used. Ron Kleiman helped with obtaining this raw data.

2015年9月21日下午2:30至5:30，环境温度约19摄氏度，本实验小组于约克大学基尔校区（York University-Keele Campus）斯壮池塘（Stong Pond）的草原样地开展了物种生物多样性调查实验。实验中，我们以样方（quadrat）为采样单元，在草原上随机连续布设25个重复样方。调查过程中，借助植物图鉴对样方内的植物物种进行鉴定，鉴定阶段同时观测了植物颜色、叶片形状与大小等特征。本次调查涉及多种禾本科植物，所有禾草均被统一归类为单一禾草类物种；共记录到的常见物种包括：普通马利筋（Common Milkweed）、百脉根（Birdfoot Trefoil）、禾草类、石南紫菀（Heath Aster）、晚紫菀（Late Purple Aster）、普通蓟（Common Thistle）、野胡萝卜（Queen Anne’s Lace）、加拿大一枝黄花（Canadian Goldenrod）以及广布野豌豆（Cow Vetch）。本数据集记录了物种类型、观测物种总数以及植物总多度。本次获取的所有数据均基于目视观测，除样方（quadrat）外未使用其他辅助工具。罗恩·克莱曼（Ron Kleiman）协助获取了本实验的原始数据。
