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.
