Before Columbus, natives would burn off land to attract grazers to the succulent new grass that grows after the burn. It could be that the hunters, of that period, realised that burn offs would attract the smaller grazers, which would be more numerous and not as dangerous to hunt as the really big animals. One mammoth might be a windfall but a hundred bison might be even better. This video suggests that this may have happened. Get rid of the forests and bring in the smaller grazers. You can see the herds for miles away on the grasslands which wouldn't happen in a forest setting.

@axeldeblois3391 Why would they? Their populations were small and they lived in smaller groups of no more than 30 or so. They had no transportation except their feet and their weaponry wasn't that effective for mass killing. To kill one mammoth would expend a great deal of energy and could be quite dangerous. They'd NEVER spend the entire day killing an entire herd. They'd never be able to process it all and it would attract all kinds of scavengers and predators which would pose another danger. One group would be quite the mammoth killers if they were averaging one mammoth per month and I doubt that this average ever happened. The risk to reward factor just wouldn't be worth that kind of effort. Those numbers could only be reached when human populations were a great deal higher and the weapons were a great deal more sophisticated.
