I agree with the sentiment, there are plenty of folk getting sick of the way things are going.
Back when the SOAC was being drawn up the wild camping arrangements were being pushed forward by outdoor activity orginisations(Ramblers, climbers, mountain bikers, canoeists, nature watchers, etc.). It wouldn't be fair to say the new laws aren't working because these folk are getting on with things quite happily.
What I don't think anyone realised how many new people would start going out simply for the hell of wild camping. Hazy as the old laws may have been the uncertainty did put some off, and I feel others took more care what they were doing because there was the knowledge that they were on someone elses property. Now there is the feeling that they have the right.....
....which they do, but some are pushing it too far. I heard of a farmer approaching a group in the summer only to have the access laws spouted in his face. They were cutting live wood to keep a large fire going, there were around eight of them and they'd been there for days but still they felt they had the right.
What to do in the National Parks? I've no idea. The parks were bandied around when the laws were being changed as being able to cope with the increased numbers. If there were restrictions placed on the parks I reckon folk would just wander further afield, dumping the problem on individual landowners. That's not on and would cause even more grief.
It'd be easy to say education was the key but the problem stems from a small number of folk who just don't give a damn. There's a good chance that having trashed an area of Loch Lomond last year some of them will be wandering to somewhere new next year.
Loch Long is certainly being hit, there are fire rings sprouting along the far shore but at least with a FC plantation there the woodland damage is minimal.
More power to rangers is probably the best bet, maybe a few signs at the parking areas with a plea not to trash the place and a couple of photos of sites to try to shame some sense into them.
Whether that'd work is anyone's guess though. The problem groups must know that what they're doing is wrong.
Noticed this year that the wee clump of trees between Balmaha and the Endrick is about half gone now.
