Using LTER data to compare experimental vs. observed drought

Research suggests that experimental droughts in grasslands and shrublands may underestimate the magnitude of loss in aboveground net primary production (ANPP) by more than half when compared to naturally-occurring droughts (Kröel-Dulay et al. 2022). Thus, drought in these ecosystems may have more pervasive global consequences for C cycling than predicted from past meta-analyses and experiments. To further investigate such discrepancies in ANPP response to drought, we propose a workshop for researchers at the All Scientists’ Meeting to discuss leveraging drought datasets from LTER sites. Specifically, we will explore comparing observational data from 12 LTER sites who have also implemented 4 years of experimental drought as part of the International Drought Experiment. We anticipate that this workshop will act as a catalyst for a manuscript highlighting potential differences in the extent of ANPP loss between observational and experimental drought across LTER sites.
