So I grew up in a climate very similar to California, and we also had annual wild fires in the winter time. After a fire everything was black, but as soon as it rained, shit turned green as if there never was a fire. In fact, there is a species of trees that requires fire for it to reproduce. A lot of the time the fires were started by firefighters on purpose because they had control over it.
I've always wondered why Cali has such a big problem with wildfires. The house I grew up in was on a hill, right next to a nature preserve and every year it would burn, but it was never an issue. One year I remember it coming really close to the house, it was touching our brick wall. So my mom called the fire department and they came and put it out just enough to stop going towards our house any further.
