BIOL2050 Lortie LAB 3: Grasslands Dataset 2 Species Abundance

We identified an easily spotted species of plant in the Cows Vetch, which flowers in a vibrant purple blossom. The grasslands provide a suitable environment because they feature a large amount of vegetation in condensed sections. The use of the transect method is efficient at identifying a specific organism over the large expanse of the grasslands area. The method is explained as laying out a 25m transact over a random line of the large area, and walking along the transact to observe the specific plant species on the line or very close to the line. We defined plants being close to the line as being within 5 feet of the transect. Our observed traits included distance from our initial point that the plant was observed, height of the plant, number of leaves, and number of flowers. Data observed and recorded on september 23, 2015 at the Danby grasslands lot of York University between the times of 2:30PM -5:30PM. Temperature was about 25 degrees celsius with winds of 15km/h. MetaData (Also on excel metadata sheet) We identified an easily spotted species of plant in the Cows Vetch, which flowers in a vibrant purple blossom. The grasslands provide a suitable environment because they feature a large amount of vegetation in condensed sections. The use of the transect method is efficient at identifying a specific organism over the large expanse of the grasslands area. The method is explained as laying out a 25m transact over a random line of the large area, and walking along the transact to observe the specific plant species on the line or very close. We defined plants being close to the line as being within 5 feet of the transect. Our observed traits included distance from our initial point, height of the plant, number of leaves, and number of flowers. Distance: Measured in feet and inches by the distance walked along the transect before encountering the Cows Vetch Species Height: Measured in feet and inches from the base of the soil to the highest flower or point of the plant # of leaves: A brief overestimate of the number of leaves on every single branch of each section of the single plant # of flowers: An overestimate of the number of flowers including newly formed flower buds, and flowers heavily wilting. All flowers included from the single plant. Crowding Rating: Given a Rating from 1-3, a crowding rating of 1 means the plant is not surrounded by any other plants by a distance of 2 feet of the plant of study. A Rating of 2 signifies that the plant is in contact or in very close proximity (1 foot radius) to 2-3 other plants of the same species or others. A crowding rating of 3 means that the plant was completely surrounded by other plants that occupy the exact same space.本数据集的观测对象为野豌豆属（Cows Vetch）中一种易于辨识的植物，其花冠呈鲜亮紫色。该草原区域为目标植物提供了适宜生境，因区内植被总量充足且分布密集。采用样线法（transect method）可高效在广袤的草原范围内定位目标物种，具体操作为：在大区域内随机布设一条25米长的样线，沿样线行进，观测样线上或紧邻样线的目标植物。本次研究将“紧邻样线”定义为距离样线5英尺以内的范围。 本次观测记录的植物性状包括：目标植物距初始观测点的距离、植株高度、叶片数量以及花朵数量。观测与数据记录工作于2015年9月23日在约克大学（York University）丹比草原地块开展，时段为当日14:30至17:30，观测时气温约为25摄氏度，风速为15公里/小时。元数据（详见Excel元数据表）如下： 1. 距离：以沿样线行进至遇见目标野豌豆属植物时所走过的路程计量，单位为英尺与英寸。 2. 植株高度：从土壤基部至植株最高花朵或最高点的高度，单位为英尺与英寸。 3. 叶片数量：对单株植物各分支的叶片总数进行粗略估算。 4. 花朵数量：对单株植物的所有花朵（含新形成的花苞与严重萎蔫的花朵）进行粗略估算并计数。 5. 拥挤度评级：采用1-3级评级体系，其中1级表示目标研究植物周围2英尺范围内无其他植物；2级表示目标植物与2-3株同种或其他植物接触或处于半径1英尺的极近距离范围内；3级表示目标植物完全被占据相同生境的其他植物包围。
