In reply to Northern Mountain Monkey:
> Interesting point! There's a couple of crags in there that are on the 'do not winter climb' list but are on the 'need cleaning of vegetation list'...
But the "does not climb in winter" list clearly states that the reason is due to the high quality rock climbing found on them, not the risk of damaging vegetation.
I've not heard any suggestion that the "need cleaning" list included anything where the problem was caused by rare or protected vegetation, rather than things like heather, grass, or general filth.
