There is probably just a very small minority of riders who ride with disregard for other users of the woods.
This is no different in many ways than people who use the public roads as a recetrack or drive dangerously. Of course nobody suggests banning cars/bikes/lorries etc from the road as a solution as it is clearly not the way.
I agree with the policing of the woods and the reporting of any type of antisocial behaviour, by anyone.
A few dedicated tracks for bikes would be a good move and has been 100% proven successful in many other similar situations.
As mentioned on the comments of the newspaper article they would probably be built and maintained by volunteers at no cost, liasing with the land owners and in sympathy with the surroundings and other users.
I see no real problem here that cannot be easily dealt with. 🙂
