We have a place here called Hoosier Prairie where they do controlled burns to keep it like the “original” prairie. Meanwhile we can’t burn leaves.
And the natives before us burned forest land to make prairies and grasslands because they knew the game didn't eat trees.
I cut thousands of trees each year, stack them all up in 2-story-house-size piles and open burn them.
Best part about it all, local governments pay us big bucks to do it.
Firewood sized logs end up being firewood. All done with machinery, to the point that the first time I actually touch a piece of firewood is when I carry it into the house.
It was what they used for fuel on prairie.
