Tracey,
Has there been any discussion with Parks about climbers maintaining climber's tracks?
Clearly Parks don't have the resources or inclination to maintain any of these (never have), so it's been back onto the climbing community.
However this is a legal grey area (well, several shades darker than that) so I wonder if the issue has been brought up with them so that (for example) a climber clearing fallen logs from an established trail isn't going to be subject to prosecution?
The climbers access to Rosea is a case in point - several fallen trees over the last few months could use attention with a chainsaw if someone can be bothered.
regards
