But does it allow fires in woodland? Official blurb suggests not:
Lighting fires
Wherever possible, use a stove rather than light an open fire. If you do wish to light an open fire, keep it small, under control and supervised – fires that get out of control can cause major damage, for which you might be liable. Never light an open fire during prolonged dry periods or in areas such as forests, woods, farmland, or on peaty ground or near to buildings or in cultural heritage sites where damage can be easily caused. Heed all advice at times of high risk. Remove all traces of an open fire before you leave.
(ends)
In terms of 'leave no trace' best places for fire may be below high water mark (ie, foreshore, where we still have public right of fishing, shooting, fires, etc) or on gravel banks/bars of rivers and burns.
Right of access to hills, and to a lesser extent forests, has a long tradition in Scotland, even if not exactly supported in law. The new law makes this tradition explicit - with few exceptions there is a right of 'responsible accesss'.
Wild camping was technically illegal but widely tolerated and carried out until the new law. Now we have harmonised the law with practice and tradition.
The canoeists will also be pretty ecstatic.
In my experience, nearly all landowners/lairds/keepers are pretty fair minded - it has been the dodgy 1% that everyone talks about. I have some worries about the minority of irresponsible countryside users too. I can understand the city-dweller, divorced from nature, dropping litter into their artificial environment. But I cannot understand folk who go to a lot of trouble to visit wild and unspoilt places and then pollute it. You would be surprised at the mess around some bothies and howffs.
