Model evaluation summary statistics and qualitative ratings for the Ryan and Amman (R-A) model for gymnosperms, from our study to evaluate post-fire tree mortality models. AUC = area under the receiver operator characteristic curve; Acc. = accuracy; Sens. = sensitivity; Spec. = specificity; PPV = positive predictive value; NPV = negative predictive value; see Table 1 for formulas. Warmer colors indicate higher values. Species are ordered from thin-barked to thick-barked species, based on species’ bark-thickness coefficient. Data used to evaluate post-fire tree mortality models are from the USA, from fires occurring from 1981 to 2016
