A classification tree with a depth of three that predicts a stand’s fuel class cluster (FCC) membership. Percentages within each box represent the percentage of the data belonging to that section of the tree. The four decimal values within each box represent the proportion of the data at that point of the tree belonging to each of the four FCCs. From left to right, the proportions are shown for the Black, Blue, Green, and Red FCC. Stand density is trees per hectare of live conifers in the canopy. Fuel type is the Canadian Forest Fire Behaviour Prediction (FBP) System fuel type assigned to the stand
