(a) heat map of regression coefficients (β) for when basal area (BA) at the 0.015 ha scale (a 6.91 m radius circle, center on the sample point), and (b) at the 0.1 ha scale (a 17.84 m radius circle, center on the sample point) of each overstory component predicts fuel loadings of each fuel component. Tree basal area was calculated from a complete census of all live stems ≥1 cm diameter at 1.37 m height, and all dead stems ≥10 cm and ≥2.0 m tall. Regression slopes and P-values are shown in text. In cases for which the regression was not significant, the background color is set to white. Scatter plots and significant regressions are plotted on Additional files 141516, and 17. ABCO: Abies concolor; PILA: Pinus lambertiana. Sample sizes are n = 112 for woody fuels and total fuels, and n = 1120 for litter and duff. Regression models were for 2011 pre-fire fuel loadings at the Yosemite Forest Dynamics Plot in Yosemite, California, USA
