Extended Data Fig. 4: Impacts of a subsequent drought are more deleterious than an initial drought for trees.
From: Divergent forest sensitivity to repeated extreme droughts
Growth declines (Δring width index) from 1,208 sites in the International Tree-Ring Data Bank to an initial drought (Initial, light red) and subsequent drought (Subseq, dark red), categorized by drought severity of both droughts via the Standardized Precipitation Evapotranspiration Index (SPEI) thresholds. For multi-year droughts, the first year of the drought was analyzed. Error bars indicate ± 1 standard error. Stars indicate statistically significant differences (*p < 0.05, **p < 0.01).
