Multivariate partial dependence plots for the best model (Fig. 3A) that used post-fire variables to predict the fall of pre-fire snags ≥ 10 cm DBH. Data were subset based on important variables for that model: pre-fire snag height and bole scorch. Threshold values for pre-fire snag height were based on bird use snag height thresholds (Raphael and White 1984, their Table 11) (Additional file 1: Fig. S20). Threshold values for bole scorch were based on where the individual partial dependence plot for bole scorch passed from snags being more likely to fall to being more likely to persist (Additional file 1: Fig. S20). Black and gray lines represent the mean partial dependence values from 15 model runs. The dashed line at DBH = 50 cm indicates where fall rates start to plateau
