Presents a predictive model for calculating the maximum spot fire distance expected when firebrands are thrown into the air by the burning of tree crowns. Variables included are: quantity and surface/volume ratio of foliage in the burning tree(s), height of the tree(s), and the wind field that transports the firebrands, and the firebrand burning rate. No validation data are available at present.
