In dry seasons around here, constant deliberate control-fire are an absolute must. There are hundreds of thousands of acres highly inaccessible and with literally a couple foot deep layer of dry dead palm prawns, branches, leaves, dead grass, branches, pine needles with then the dried upper grown grass and bushes too. If that gets going by a fire, usually caused by lightling storms, the fire is intense and difficult to reach if not impossible.
For this, every year, there is a bulldozed maze of fire lanes for access - which double somewhat as fire slow-downs. However, there also are continuous controlled burns too to limit how much a fire can spread - as fire won't burn thru an already burned out patch. Yet the areas so diverse and government owned, no one complains.
In California and apparently Arizona and other areas, homeowners don't what patches of wildland near THEIR houses control burned. As a result, there will always be "out of control" and enormous wildfires there. Fighting fire with fire is a necessity, and when denied the result WILL be massive fires and lose of life and property.
If one studies nature without human intervention, fire is a natural cycle both to prevent catastrophic mass fires and for new growth and new life. But no one with a house in the hills or mountains wants to see a patch of burned land while driving home, so this isn't done - and the consequences 100% predictable later - a worse, more destructive and more deadly fires.
