That’s a whole lot of work.
Can you clear with controlled burns?
Pretty sure they are using it as a barricade against the trespassers.
No, burns have their own complications.
More typical is gathering together and burning in a pile, but I just decided to let it build up.
You actually end up with spread in a pasture burn, so you have to spray it first with what is effectively a selective Agent Orange, then bulldoze it.
Plus, there are flow lines with either crude or salt water or frac water all over the place (the roll back in forth in the Sun). They’re just polyethylene lines and would catch on fire.
