WebPost-fire tree mortality was greatly influenced by slope when holding DBH and BSI constant. For instance, a tree with a DBH of 50 cm, BSI of 10, and slope of 0° had 6% probability of tree death, whereas the same tree on 20–30° slope experienced a 23% probability of death. A BSI ≥ 25 almost ensured tree mortality regardless of DBH and slope.
