Don’t think there’s much you can do to stop people digging holes, suppose you could always fill them in, but then do you have any more right too fill them in than they have to dig them, it’s not like they’re officially sanctioned trails/runs ?
Same with litter, not much you can do other than pick it up, maybe a few signs something like
DO NOT LITTER!
ACCESS TO THIS LAND IS NOT A RIGHT AND IS GRANTED BY KIND PERMISSION OF THE LANDOWNER, BY LITTERING WE WILL LOOSE THIS PERMISSION AND YOU’LL SPOIL IT FOR US ALL.

CONCERNED RIDERS.
Its a pretty quite spot, advertising it’s existence on here’s not going to help.
