In reply to ERU: Pretty much spot on here. I contacted a few frineds in CCW today who funnily enough had had a call from another member and gave me a pretty good answer which cut and pasted reads.......
Jonathan,
Thanks for your phone call.
These are extracts from the e-mail from our upland specialist, Barbara
Jones.
"Generally there isn't a problem regarding snow & ice climbing on
cliffs, as the plants are dormant or covered in snow/ice. However, the
concerns arise when conditions are lean - i.e. little snow/ice cover,
but frozen turf. In these conditions, ice axes and crampons can
possibly do some damage if either a lot of people climb a particular
route or if there are sensitive species/communities there. To try and
inform people about these issues, I've written pieces for the BMC
webpages together with their access and conservation officer for Wales
(see
http://www.thebmc.co.uk/Feature.aspx?id=3469 ) and am currently
working with the guidebook writers in N Wales, to include sensitive
areas on their crag diagrams so people know what to avoid."
"In Snowdonia, the arctic-alpines and tall-herb ledge communities could
be affected, but I went up to look at the main ice climbing cliffs in
June where I know the botanical importance is high. I found no evidence
of damage, but obviously it is something we need to keep an eye on. Go
to
http://www.thebmc.co.uk/News.aspx?id=3877 to see the article about
this visit."
There is much less potential for damage at Craig-y-llyn than in
Snowdonia but we would ask people to avoid climbing when there is little
snow or ice and just frozen turf. You told me that there would not be
the same reason to climb then anyway.
Do ask if you need anything more specific. I thought I would copy in
RCT's ecologist for information.

As ERU said, if the ice is well formed it is not a problem although officially permission should be sought from FCW. Having contacts and work with FCW i will call them tomorrow and ask about permissions etc.
An earlier post said that CBMRT were stopped from training there. I would suggest (Being a former member of the said team) it is because the CBMRT would cause damage. I say that because when they set up a belay the number one concern is safety. If I remember we used to used six huge metal posts hammered into the ground. Those posts would cause damage albeit small, however that small damage could cause irrepairable damage that the eye cant see. When most of us climb, we would be placing protection via screws into the ice. On the SWMC site is says there are no sports routes, reason being this would involve drilling into the rocks etc.
Happy climbing.
Jonathan
