Plant species percent cover data: The influence of natural enemies on plant community composition and productivity

The purpose of this experiment is to determine the influences of natural enemies, including plant pathogenic fungi and insect pests, influence plant community composition, productivity, and diversity over time. The experiment is being conducted in an old field that is burned every other year. Within the old field, there are 8 blocks, and within each block there are 6 treatments: foliar fungicide, soil drench fungicide, foliar insecticide, mammal exclosure, the combination of all enemy suppression tactics (pesticides and mammal exclosure), and a nontreated control. The pesticides are applied repeatedly throughout the growing season. Within the plots, community productivity, species composition, percent cover, and pest damage are being quantified over time.本实验旨在探究包括植物病原真菌与昆虫害虫在内的天敌对植物群落组成、生产力及多样性的随时间推移所产生的影响。本实验于每两年焚烧一次的弃耕农田中开展，该农田内设置8个样块，每个样块内包含6种处理方式：叶面杀菌剂处理、土壤灌施杀菌剂处理、叶面杀虫剂处理、哺乳动物驱离处理、所有天敌抑制策略联用处理（杀虫剂施用与哺乳动物驱离联用）以及未处理对照组。实验期间将在整个生长季内重复施用农药，样地内的群落生产力、物种组成、盖度百分比及害虫危害程度将随时间进行量化测定。
