Here's my suggestion to the OP and anyone who is in a similar situation. Go out and stop him! Geez. We've had a number of people attempt to do the same thing to us, and if we notice they are planning to take every tree for themselves, we try to talk to them first, and if they don't respond we take action. The safe zones already protect any resources from outsiders, so anything outside of that border is fair game, period. And, that's how it should be.

The only thing necessary for evil to triumph is for good men to do nothing. If you don't want to get walked over, get out there and do something to stop them.
