Aboveground vegetation cover and biomass in plots with experimentally altered precipitation and nutrient inputs at the Jornada Basin LTER site, 2006-ongoing

This dataset contains cover and biomass data collected starting in
2006 for a long-term precipitation and nutrient manipulation
experiment at the Jornada Basin LTER site in southern New Mexico,
U.S.A. This experiment uses precipitation shelters and irrigation
treatments to manipulate water inputs, and fertilization treatments
to alter nitrogen input to 2.5 x 2.5 meter plots in a desert
grassland. Plant cover measurements are made annually in each plot,
from which biomass or net primary production are derived. This is an
ongoing study and the dataset will be updated yearly.
