Extreme drought decreases the stability of above- but not belowground productivity across Eurasian steppes

Data were collected annually from 2016 to 2018 across six representative grassland sites in Northern China as part of the Extreme Drought in Grasslands Experiment (EDGE). The sites spanned a range of grassland types and climatic conditions in Northern China, selected to capture regional variability in ecosystem responses to extreme drought. At each site, ANPP, BNPP, and community variables were measured in experimental plots subjected to extreme drought treatments and ambient controls.
