Lab 3- sweep net dataset

This experiment was conducted in the grassland at York University on September 30th, to measure the population density of insects in the mowed and un-mowed grassland. A total of 10 replicates was collected, in which 5 was collected in the mowed area and 5 was collected in the tall grass area. This was done by placing the transect measuring tape at random for a distance of 30 meters on the ground. Once the tape was placed, a sweeping net was used while walking along the tape for a period of 2 minutes. After every 10 sweeps we observed what kind of insects were caught in the net and recorded the findings. This was repeated for a total of 10 trials

本实验于9月30日在约克大学（York University）草原样地开展，旨在测定刈割与未刈割草原的昆虫种群密度。共设置10组重复采样，其中刈割区域与高草区域各采集5组。采样时先将样带卷尺随机铺设于地面，布设长度为30米；卷尺布设完成后，沿其铺设路径行走，同时使用扫网开展时长2分钟的扫捕作业；每完成10次扫捕后，对网内捕获的昆虫种类进行识别并记录观测结果。上述采样流程共重复开展10次。
