Fig. 5. Effects of fuel structure on fire severity across five levels of topo-weather.

Slope estimates (β₁), standardized by z-score, represent the univariate linear effects of GEDI-derived fuel structural variables on dNBR wildfire severity from a series of spGLMMs. Model results were obtained from all data samples (“all”) in addition to subsets defined as five equal-sized classes stratified by corresponding topo-weather variables. Median posterior estimate (points) and associated 95% credible interval (error bars); terms not significant (open symbol) when the credible interval includes zero (dashed vertical line).
