There was big thing back in the 1950s wit( the right to roam where certain places were declared public footpaths and rights of way even though many are in private hands.
They have to keep the: accessible as well or they get billed by the council for carrying out the work.
A lot of rights of way have to do with usage over time, and that if somewhere is used over a long time it becomes a right of way. That’s what the landowner wants to avoid, he doesn’t mind people using the land but he doesn’t want it to become a right of way. Placing a restriction stops that happening.
