Classification tree model showing the probability of prescribed fire resulting in damage to Cladonia samples associated with different combinations of the independent variables measured in this study (Tables 1 and 2, Fig. 4). Nodes representing the important independent variables (1 through 3) and outcomes (4 through 7) are connected by lines representing splits driven by the values of the independent variable at the higher-level node. A probability distribution of outcomes is presented in the bottom row where the terminal nodes represent both the model prediction associated with a given combination of independent variables (e.g., that the sample would be consumed at node 4) and the observed dispersion of outcomes within a given node, where C = consumed, F = fragmented, and I = intact
