I have wandered this land since childhood.
The only places I could not do so were on the MOD lands down the Clyde estuary.
Anywhere else to be somewhere just for a walk wasn't an excuse, it was a reason. Camping for a night or two if you did no damage most folks never minded. Usually offered you fresh water and hinted that the wife had eggs and veggies for sale
Land that sees a lot of people using it needs stewarding in this country. No getting away from it, we have an appalling habit of dirt and destruction.
Look around any area after the school kids have been out for lunch and there's the cleansing dept clearing up after them.
They carry that throw away, knock it down, kick it over attitude into adult life. They go to Loch Lomond and the like and get rat assed maroculous and think they're having a good time
No other situation with so many visitors would have such truly dire infrastructure. Not enough bins, not enough toilets, not enough stewards, not enough signages (and yes, the numpties need the keep off the cliff signs
)
Is the answer restrictions ?
No.
It's education in the long term and in the short term more publicity, more rangers, more application of the fines already available; more police and more public infrastructure.
Scream it out in every tabloid in the country, "don't trash, don't cut down trees, bury your sh1t away from watercourses".
And for heavens sake some enterprising businessman with a wee lorry run along the lochside selling bags of sticks. He'd make a wee mint. It doesn't even need to be well seasoned for household use stuff, those idiots'll no' care so long as it burns.
cheers,
Toddy
