The BIODESERT survey: assessing the impacts of grazing on the structure and functioning of global drylands 2022 Access copy available to the general public Unrestricted Grazing by domestic livestock is both the main land use across drylands worldwide and a major desertification and global change driver. The ecological consequences of this key human activity have been studied for decades, and there is a wealth of information on its impacts on biodiversity and ecosystem processes. However, most field assessments of the ecological impacts of grazing on drylands conducted to date have been carried out at local or regional scales and have focused on single ecosystem attributes (e.g., plant productivity) or particular taxa (mainly aboveground, e.g., plants). Here we introduce the BIODESERT survey, the first systematic field survey devoted to evaluating the joint impacts of grazing by domestic livestock and climate on the structure and functioning of dryland ecosystems worldwide. This collaborative global survey was carried out between 2016 and 2019 and has involved the collection of field data and plant, biocrust, and soil samples from a total of 326 45 m × 45 m plots from 98 sites located in 25 countries from 6 continents. Here we describe the major characteristics and the field protocols used in this survey. We also introduce the organizational aspects followed, as these can be helpful to everyone wishing to establish a global collaborative network of researchers. The BIODESERT survey provides baseline data to assess the current status of dryland rangelands worldwide and the impacts of grazing on these key ecosystems, and it constitutes a good example of the power of collaborative research networks to study the ecology of our planet using much-needed field data. info:eu-repo/grantAgreement/EC/H2020/647038/EU/Biological feedbacks and ecosystem resilience under global change: a new perspective on dryland desertification/BIODESERT This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 647038-BIODESERT info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.2 2022 ENVIRONMENTAL SCIENCES 202 / 275 = 0.735 2022 Q3 T3 ECOLOGY 97 / 171 = 0.567 2022 Q3 T2 0.65 2022 Ecology, Evolution, Behavior and Systematics 2022 Q2 Ecology 2022 Q2 3.4 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Eldridge, David J.
