Google Earth has produced a timelapse of bush fires in Australia that is illuminating.
The animation shows fire scars appear, fade and be overwritten by a new fire. Though fire size seems to be increasing in Australia, this process creates patchiness and resiliency in Sierra Forests, But it takes place over the hundreds of years cycle of forest tree growth, rather than the few years of brush and grasslands, so it's harder to see.
