Is there any evidence of this? I mean, I know that the indigenous people did so to try to contain fires, because wildfires have been an issue for millions of years. But is there any evidence it was "more successful" historically? I'm not a huge believer that ancient cultures had these things figured out.
I'll let you go into the further reading section for more information.
Please explain the type of evidence you could gather that would tell you American Indians thought intentional burning was a good idea and part of their planned forest management.
From what I'm reading on your link the evidence is evidence of fires burning things down, thus the Indians had an advanced forest management system in place.
It turns out that people that lived in fire country for hundreds/thousands of years built up practices of burning when fires would remain calm rather than explode into conflagrations. "Advanced" is relative in this sense.
Between this and natural fires the landscape had a patchwork quality that acted as natural fire breaks.
