Yup! I recently read about aboriginal tribes doing controlled burns during the winter, rainy seasons etc. They even noticed certain plants would grow more afterwards, attract certain animals etc

while you are not wrong, there isn't really anything else we can do. At this point the best thing to do - because it is the only thing feasible - is let the first burn, and then start over by doing the regular burns that forests need. We know from other fires that forests tend to recover a lot faster than you would expect and so in a decade we will have healthy forests again.

Sure, if you can put in a large fire break across a province/state and burn just one side this year, and the other side next year that would be good. However both need to burn and there is no way to do just a small area every year and catch up to where the forests need to be.

We've been suppressing fires for decades, allowing underbrush to build up creating even worse conditions for fires.

Either we let it burn, or make a conscious effort to clean up the underbrush ($$$). There is nothing we can do to reverse climate change fast enough to stop this.

In combination with poor forestry fire management. Which is essentially what I was getting at.

The Permian extinction was caused by the basaltic flood eruptions that created the Siberian Traps, with a volume of four million cubic kilometers of lava. That's not happening here.
