Fig. 4From: Short-term recovery of post-fire vegetation is primarily limited by drought in Mediterranean forest ecosystemsPartial dependence plots showing the marginal effect of predictor variables (x-axis) on post-fire vegetation recovery (y-axis) for three aridity areas in the western Mediterranean basin. The predictor variables analyzed were a the maximum number of consecutive weeks with Standardized Precipitation Evapotranspiration Index (SPEI) values of < − 1; b fire severity, measured in relative difference normalized burn ratio (RdNBR) values; c the northness index; and d the topographic wetness indexBack to article page
