Interesting thread, and some really good contributions (especially boxelder, rangerbill etc.). Apologies for the extended monologue below – but I was musing this thread earlier...
There is a myth perpetuated (including by some on here) that ramblers and horse riders (for example) are all in support of this kind of work being carried out. This simply isn't the case. Many enjoy rougher tracks, less visually intrusive paths and more 'natural' feeling routes. And this isn't about 'accessibility' either. A friend of a colleague has published some good studies involving blind walkers organisations, suggesting that part of the value they find in being able to use off-road routes is the engagement offered by different and unpredictable surfaces – not merely a uniform road that can be repeated anywhere (albeit amongst some pretty scenery). The fact is that there are a whole range of motivations that make people want to be able to access a particular area or route – and not all will be compatible, all the time.
The current system of ROW/ access legislation/ policy/ practice does not seem to acknowledge this, and rather presupposes that if a user is able to access a route that is all that matters, and the nature of the route itself is immaterial. In fact, judging by my experience, and the views expressed on the thread, the very material of a route is crucial to the experience of many of us. Walkers, fell runners, mtber's, horse riders, climbers and so on all seem to enjoy particular routes for their very difference, rather than their uniformity. Why is it not possible for authorities to have an attitude towards access that celebrates and promotes this diversity, rather than one that suppresses difference and tends towards a misguided understanding of why access is important in the first place?
The difficulty then clearly is how to deal with or manage issues around 'damage' to routes, and the impact that users have on the routes they clearly value. How do you feasibly manage access without infringing on rights or fundamentally changing the nature of that access? I can't help thinking that having a planning system that is based on a notion of limited rights against a backdrop of presumed non-rights (all of course based on reductive and contested historical precedent) doesn't help, as it confers the entire responsibility regarding access to 'authority' and absolves us from any personal responsibility. 'They' provide it, 'we' use it. It seems if they ensure access where legally required to do so they have done their job (regardless of the nature of this or how this is achieved), and as long as we remain legal in our access (regardless of the potential effects of legal or non-legal use), all will be well. It's hardly surprising that this system ends up creating or adding to tensions between individuals, and does little to address the reasons why such intensive and controversial management of access is seen to be necessary.
Anyway, to get back towards the thread...
It does seem bizarre that local authorities can be seen to 'improve' ROW in a (sometimes) heavy-handed manner with little consequence, while at the same time a whole host of groups like Natural England (IIRC?) , John Muir Trust, Mountaineering Council, and Ramblers Scotland are actively involved in working or campaigning against large engineered works carried out by private estates – leading in some cases to prosecution, and in others to the active removal of precisely these types of track road.
