No native writing system was known among North American Indians at the time of first European contact.

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.

Instead of being argumentative about this, look where we actually have documentation, which is aboriginal burns in the AU.

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.
