Plant biomass collection on the Biodiversity Experiment at the Kellogg Biological Station, Hickory Corners, MI (2001 to 2011)

Dataset Abstract The biodiversity gradient experiment is an additional long-term study located within the LTER Main Site complex, in which a series of 21 different experimental treatments vary in plant species diversity. Treatments range from bare soil to single-crop rotations to multiple-crop rotations to annually fallowed fields with early successional plant communities. Plant species richness thus varies from 0 to >15 in any given 3-year rotation cycle. Treatment plots are 9.1×27.4 meters (30×90 feet) replicated in each of 4 randomized blocks. The study site was established in 2000. original data source http://lter.kbs.msu.edu/datasets/112数据集摘要 本生物多样性梯度实验是位于长期生态研究网络（LTER）主站点群内的一项附加长期研究，共设置21种不同的实验处理组，各组植物物种多样性水平存在差异。处理组覆盖范围从裸土、单季轮作、多季轮作，直至每年休耕并伴生早期演替植物群落的地块。因此，在任意给定的3年轮作周期内，植物物种丰富度从0变化至15种以上。实验样地规格为9.1×27.4米（30×90英尺），在4个随机区组中均设置重复。该研究站点于2000年正式建立。原始数据来源：http://lter.kbs.msu.edu/datasets/112
