Here's what the hills around LA and Pacific Palisades look like:

Above is the tram station at the Getty museum that takes patrons up the hill to the complex that is "the Getty". The trees in the foreground are the exception not the rule for this part. When it rains enough, the hillside goes very green. A month later, it's back to bleak.
You might remember back in 2018??? they ran video of people driving through the tunnel of fire on the 405 in LA... It was that fire that threatened the Getty, and a lot of talk was "when are they pulling the artwork out for safety?" (It was safer in the concrete positively pressurized buildings.) It was hillsides like the one here that were burning.
The idea that you could remove the parts that are dead doesn't hold water in areas like this. That's not dead. It's dormant.
Below is a similar hillside from the Culver City Overlook. Closer view of what vegetation there is there. Again, dormant, not dead.

And one from a Santa Barbara vineyard. More trees, but not forested. Its areas like this that burn. Broken power lines, Careless campers. Homeless trying to make a hot meal. It doesn't take much to make this stuff go WHOOOSH!
