Partial dependence between observed site fire effects on artifacts and features and important predictors for archaeological sites within perimeters of fires that occurred from 2000 to 2011 in the Jemez Mountains, New Mexico, USA (n = 858). (A) Two-way partial dependence (y-axis) for Existing Vegetation Cover (EVC; each box) × Slope-Cosine_Aspect Index (x-axis). (B) Two-way partial dependence values for mean fire season ERC (Energy Release Component, a composite fuel moisture index) and percent of normal, mean annual precipitation. Larger (more positive) partial dependence values, shown as lighter green and yellow colors, indicate a greater likelihood that a fire effect will be observed at the corresponding predictor value. Smaller (more negative) partial dependence values, shown as darker green and blue colors, indicate that a fire effect is less likely at the corresponding predictor value. See Table 2 for full description of EVC classes and other variables. Plots for other predictors are presented in Additional file 1: Figures A1.1 and A1.2
