Data for: Extreme drought impacts have been underestimated in grasslands and shrublands globally

Data for publication \"Extreme drought impacts have been underestimated in grasslands and shrublands globally.\" In this publication, we used a globallly distributed network of drought experiments to assess the impact of extreme, single-year drought events on aboveground net primary productions in grassland and shrubland ecosystems. The data and script necessary to reproduce figures and analyses for the manuscript may be found in this repository. The single script combines all of the data frames in order to run statistical models, create figures, and produce any additional statistics referenced in the publication. Data in this repository include the reponses of aboveground net primary production to drought treatments at 100 sites, abiotic information about the sites such as mean annual precipitation, annual precipitaiton, and soil sand content, along with biotic characteristics about these sites including species richness and the percent of vegetative cover by graminoids. Though the ..., Aboveground net primary production data were collected in 100 drought experiments around the world. These data and scripts were used to explain responses of plant production to drought experiments. Please see published manuscript for detailed methods., , # Data for \"Extreme drought impacts have been underestimated in grasslands and shrublands globally\"

## Description of the data and file structure

The structure of this repository is relatively simple, with one single R script (Dryad_submission.R) which uses data from seven .csv files in order to reproduce results and figures from the publication. The datasets can all be linked by the site_code column which is the unique identifier for each of the 100 sites in the study.

Dryad_data_site_info.csv

This file includes information for the sites in the Drought Network International Drought Experiment including the full name, continent, country, habitat type, mean annual precipitation, and aridity index values.

**dt3.all.csv**

Contains information as to the mean drought response at each site (mean_DS3), number of replicates at each site (n), standard deviation of response (sd), standard error of response (se), lower and upper bounds of 95% confidence interval, and whether the site was si..., , **Changes after Jan 17, 2024:** Added data.Drtsite.csv file.
