Like all databases, the BMC RAD is only as good as the information that is uploaded to it, so it needs to be fully supported with someone keeping it updated in real time by checking with other organisations regarding the situation with nesting birds etc. This should include local RSPB/NT/NE officers and not just those at Head Office.
There has been many cases of nesting birds/birds not nesting on Cornish cliffs over the years, yet either that info doesn't get to the BMC, or it's not inputted onto the RAD or the info amended, in good time - The annual Chough nesting situation, at Chair Ladder, being a case in point. (The birds might not nest at the same site, or leave earlier than the end of June). Looking at the RAD this morning, it seems this now considered an annual restriction for the foreseeable future, whereas the restriction only came into being because the Choughs had moved from their usual nest site, near Chair Ladder, onto the cliffs one particular year.
Fortunately, Carn Gowla isn't the most popular of crags, but it has it's disciples (me included) and, being local, I am aware of the current issues, so stay away. A good social media campaign by the BMC about the Carn Gowla situation (and the RAD) would help prevent any unfortunate incidents that could jeopardize access, but not everyone uses UKC/social media. The NT and NE need to recognise this and understand that there may be the (very) occasional genuine mistake, especially if they aren't prepared to put a sign up at the main car park (let's be honest, I doubt anyone could be paid enough to put signs up at all the abseil access sites at Gowla).
Local BMC reps (unpaid volunteers) are doing their absolute best to ensure we get to keep climbing at the crag, so they need our support. Losing access here could be the thin end of the wedge, with loss of access to other, more popular, crags due to nesting birds (and other wildlife). When I first started climbing in Cornwall, there were no bird bans, except on Porthmonia Island. Now there are at least 5. Hence, the issue with climbers using older guidebooks that contain outdated information.
As for the Bonatti Pillar (which I've done), I doubt the latest generation of climbers even know who Bonatti was, or about his contribution to climbing.
