Both of our contries have been "managed"for millenia...your praries need management large herbic=vores and fire, otherwise they return to tinder...can't maintain parrie with fire alone.
Oz, the indigenous population managed the environment for thousands of years...yes they changed it massively...but that's what it was for 40+ thousand years...
Neither of our official histories will reflect this level of management, or the civilisations that maintained it, as that would be...uncomfortable.
So under pressure from certain groups, and lack of budgets, all these areas get lock gated, and called "national parks"...and left to nature...and it grows and produces fuel.
Then when the fires come, they are ridiculous, like these...both sides of the Pacific.
If we keep them locked up, they will keep doing this until over a few hundred years, the vegetation evolves to a NEW natural state that doesn't involve these infernos...or we manage them, but that's expensive, and involves large herbivores, and money.
Unless we get as cleveras those that we've displaced, and create abundance from that management.
