A simple cellular automaton replicates the fractal pattern of a natural
forest landscape and predicts its evolution. Spatial distributions and
temporal fluctuations in global quantities show power-law spectra, implying
scale-invariance, characteristic of self-organized criticality. The evolution
toward the SOC state and the robustness of that state to perturbations
