  This paper focuses on the statistical properties of wild-land fires and, in
particular, investigates if spread dynamics relates to simple invasion model.
The fractal dimension and lacunarity of three fire scars classified from
satellite imagery are analysed. Results indicate that the burned clusters
behave similarly to percolation clusters on boundaries and look more dense in
their core. We show that Dynamical Percolation reproduces this behaviour and
can help to describe the fire evolution. By mapping fire dynamics onto the
percolation models the strategies for fire control might be improved.
