His family should file a wrongful death civil suit against the Sierra Club and other organizations that have used their influence to stop the logging of dead timber and the clearing of brush.
I grew up there. I spent a lot of time in Pioneer Town. It's high desert area. Most of the brush is dry throughout late spring and summer, but greens again briefly in fall.

It's not possible.
