That's not the justification. The author is bringing up traditional burning practices because suppression of those practices is a cause of our current mega fires.
"Thanks to centuries of overzealous fire protection and the suppression of Indigenous cultural burns — which Europeans found “primitive” — forests have become overgrown, accumulating piles of underbrush and fallen trees. In trying to prevent wildfires altogether, we’ve been essentially storing up bigger and bigger piles of fuel. And with that extra fuel comes fires that burn more ferociously, exacerbated by drought and drier conditions from climate change.
“When you talk to different native people from the Yosemite area, they talk about how it used to look when fire was used as a management tool,” UC Davis professor of Native American Studies Beth Rose Middleton Manning said in a University of California article. Areas that were once open valleys are now choked with conifers and other fuel sources that were not there when cultural burns helped groom the land."
The justification for controlled burns is written here
"Setting fires intentionally may sound like a paradoxical approach to fire control, but if they are done correctly, controlled burns reduce the fuel available for wildfires, helping to prevent the catastrophically large, hot fires that overwhelm firefighting resources. They also are beneficial for a healthy ecosystem."
It sounds like you'd like to know more about wildfire and how indigenous burning practices suppress mega fires. I encourage you to read the linked materials, as this little article isn't going to go deep enough to answer your questions.
