That is correct Bandwagon. No intention to start "something", and we all know trespassers, littering etc are the source of problems. However I happen to know a few landowners who don't mind, if people enter their land........Im sure there are many more.
Those who do not want people on their property, indicating so, is very easy. If your property doesn't fall under those that are automatically "prohibited" or assumed to be "prohibited"....Put some red dots or signs up. It not hard to announce to the world.
visitors not welcome, or "X activity not welcome".
Personally I would recommend people be familiar with the law. And not suggest those who are within the law, are causing problems. Any landowner who for any reason be it finding too much litter, or was an "anti" who was having problems with people on his/her land, just simply has to post a sign. So "hunters" or birdwatchers, who are legally going onto land where they are permitted to be and go....aren't a problem, nor source of problems with more land owners saying no to hunters.
