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