I really enjoyed watching the recently uploaded Youtube film on the release of beavers at RSPB Loch Lomond:
(6) BEAVERS AT LOCH LOMOND - the inside story of bringing beavers back - YouTube
I do hope:
1) there will be a series of updates on how the beavers are getting on engineering the habitat for greater biodiversity; and
2) assuming the project is successfully, there will be other projects like this at other RSPB sites in future.
