Prescribed burns (intentional, hopefully controlled, fires) are increasingly common in modern forestry and wildfire prevention. They're done in Canada and Australia, and from a quick search, it was brought back into practice in the 1990s in the USA.

Parks Canada has an interesting FAQ about their practices: https://parks.canada.ca/nature/science/conservation/feu-fire...

In South Australia, they're very much monitored and controlled. In the Northern Territory however, it is not uncommon in season to see fires burning beside the highway in a national park, and no one anywhere nearby monitoring them. Well, that is besides birds who hang around to nab fleeing insects and other creatures. Birds have been known to carry burning twigs elsewhere to spread the fire too.

Coming from the former region and visiting the latter, it's quite jarring. But that (now called) mosaic burning has thousands of years of history. You can easily see how it advantaged the early occupants of the area: reduce overall fuel load, flush out animals to hunt, and clear annoying tall, dry grasses which would be miserable to live amongst and walk through.

Prescribed burns are much more common in the southeastern US than in other areas: https://www.wabe.org/why-the-southeast-is-ahead-of-the-west-...
In Western Australia they are a racket. Land is burned for burning's sake as an area of required burning is defined and people rush to hit a quota. Studies are showing that land left untouched for years is actually less flammable than land in the medium turn after burn-off. Additionally, the effects on air quality cannot be discounted either. It is a politicized issue and people are terrified of being seen as not doing anything to combat bushfires that would otherwise threaten homes.
this comment is useful to show how opposed various parties can be.. I have > forty recent, peer reviewed forestry sciencepapers on this topic here in California, where I share them with others who want to educate themselves on the topic.. here we share some characteristics with some parts of Australia regarding wildfires.. in recent years, the severity and scale of some fires have shattered previous records.
