Long-term tallgrass prairie percent cover from the Rainfall Manipulation Plot Study (RaMPs) at Konza Prairie Biological Station (1997-2012)

Vegetation percent cover data from a long-term precipitation manipulation experiment was
used to determine how higher precipitation variability (fewer, larger events) will impact
plant community structure and species composition in annually burned, native tallgrass
prairie. The study was conducted from 1997-2012 in the Rainfall Manipulation Plots (RaPMs)
at Konza Prairie in northeastern Kansas, USA. The RaMPs infrastructure maintains total
ambient growing season precipitation with half the plots (n = 6) receiving a rainfall regime
that includes fewer but larger rain events and longer intervals between events during each
growing season.

本研究采用长期降水调控实验获取的植被盖度百分比数据，旨在明确降水变率升高（即单次降水事件更少但量级更大）将如何影响每年焚烧的原生高草草原的植物群落结构与物种组成。该实验于1997年至2012年在美国堪萨斯州东北部的康扎草原（Konza Prairie）的降水调控样地（Rainfall Manipulation Plots, RaPMs）开展。该RaMPs实验设施维持了生长季总降水量与自然环境一致，其中半数样地（n=6）采用的降水格局为：生长季内单次降水事件更少、量级更大，且事件间的间隔时长更长。
