In reply to goose299:
Yes, I'm with Jon on this one. The number of people you meet on crag based scrambles is very few for the large part of the year, let alone the Ghylls, even though it is meant to be quite a popular activity.
Yearly floods and sediment transport will scour a lot more vegetation than the handful of scramblers. As a scrambler myself, you do tend to look for the clean rock as a preference for handhold/footholds instead of vegetated areas when on routes.
What may be of interest is the path that is created in getting to a scramble, because these are not the obvious or natural lines of ascent for a hillside. They will be caused by people doing a particular route.
