Partial dependence between site burn severity and environmental predictors for archaeological sites in the Jemez Mountains, New Mexico, USA. Shown are six predictors determined to be important for predicting site burn severity in our study of 858 sites assessed after five wildfires that occurred between 2000 and 2011: (A) Elevation, (B) Heat Load Index, (C) Slope-Cosine-Aspect Index, (D) Percent Slope, (E) Compound Topographic Index, and (F) Linear Aspect Index. For (F) Linear Aspect Index, N = north, S = south, E = east, and W = west. Burn severity is represented as follows: high burn severity is a short dashed line, moderate severity is a dotted line, low severity is a long dashed line, and unburned is a solid black line. The y-axis represents the probability of observing a particular burn severity class for each predictor value, holding all other predictors constant at their average value. Larger (more positive) partial dependence values correspond to a greater likelihood that a severity class will be observed at the predictor value indicated on the x-axis. Smaller (more negative) partial dependence values indicate that a severity class is less likely at the corresponding predictor value
