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.
