In reply to climbingpixie:
The easiest place to get up-to-date bird restrictions information and advice is the FRCC website (frcc.co.uk) and, of course, posts on this forum. I post whenever there are changes to restrictions. The situation with Castle is a request rather than a formal restriction.
The RAD sometimes takes a little time to update (not my patch) and the crag moderators are the people to update the crags database.
On the subject of ticks I can throughly recommend Armathwaite in July and August, you may be surprised if not embarrassed at where the light blighters can take hold.
