Hmm. Sounds like it's in their too-hard basket and has been for many years now. Makes it hard to know how they really feel. If it wasn't for this forum I'd have no idea about any of this!
Certainly we have the impression that authorities would much rather be able to say "don't do it" and have the problem magically go away.
Obviously this is not happening. There are a large number of casual mountain bikers in the ACT, the "cyclists on formed roads" signs are ambiguous because it could be argued that an obviously constructed bike track is a "formed road". The street directories and even plans of the nature parks showing equestrian trails indicate that there are multi use (including bike) trails in the nature parks.
A complete re-think and a consistent and clear strategy is required.
At present, not only is there non-compliance, but the message that is supposed to be complied with is exceedingly fuzzy.
We're working on it, the problem is that it's not at the top of the list for Parks management and, given that we have other trails to look after, develop and protect such as Sparrow, Majura etc it's not first cab off the rank for the CORC trails folks either.
The work that Ross has been doing helps a lot as it indicates that riders are responsible and care about their impact, but it's still tweaking the edges of an illegal trail network. We are working on it and there is a willingness to deal with it from both the CORC and the PC&L end of things, it's just that resources are limited on both sides.
Head in the sand, sticking things in the too hard basket and putting up with the status quo doesn't help anyone terribly much.
Trust me, it's high on the "to do" list and things will progress once the World Champs is out of the way.
