Abstract: Cellular automata for heterogeneous bushfire propagation are introduced and their critical properties studied. The underlying models assume continuous fuel with variable moisture characterized by either a fixed value or a random choice of extinction determined by the moisture level. Elliptical (circular) propagation from a single ignition point is assumed. Classes of universality are very stably identified to be those of directed and undirected percolation, despite a significant range of variation of the many parameters involved.
