In the original enclosure there is a dam of about sixty metres length. The end of it has been turned into a canal. This is the short canal that skirts one of the exclosures that Kevin Jones built when he was doing his PhD here some years ago.
The idea was that the exclosure would stay and others would come and go on with some monitoring.
The beavers, however, have thought otherwise and broken into the exclosure. The willows in there are their reward.
