Plant diverity and richness metrics across inter-annual precipitation variability treatments at a grassland site in the Jornada Basin, 2009-2014

This ongoing dataset contains metrics of plant diversity, evenness,
and richness from a study at the Jornada Experimental Range (JER) in
southern New Mexico. The study was designed to assess the effect of
interannual variability in precipitation on average aboveground net
primary productivity (ANPP) in Chihuahuan Desert grasslands. The study
began in 2009, has five precipitation treatments (see Methods) and
contains 50 plots (10 per treatment). This data package contains
6-year (2009 to 2014) means of metrics per plot. Annual and more
recent data are available and will be released pending an upcoming
publication.

本持续更新的数据集收录了新墨西哥州南部霍拉达实验牧场（Jornada Experimental Range, JER）一项研究中的植物多样性、均匀度及物种丰富度指标。该研究旨在评估年际降水变异性对奇瓦瓦荒漠草原地上净初级生产力（aboveground net primary productivity, ANPP）平均值的影响。研究始于2009年，设置5组降水处理组（详见研究方法），共包含50个样地，每组处理对应10个样地。本数据包收录了2009至2014年共6年间各单样地指标的平均值。年度数据及最新观测数据均可获取，待后续正式发表后将对外发布。
