I hadn't visited the swampy ground behind the Curling Pond for a couple of months, so it was very interesting to see the extension of the dams to form terraces, the extent of grazing of the new sward and the colonization of the ground by bogbean (Menyanthes trifoliata).
Although the beavers seem to be using their oldest lodge still, they have built a couple of new lodges on the bank of the short canal that links the two ponds.
Neither of these lodges is as extensive as the original lodge, whose construction they started on in the autumn of 2002.
This photograph shows the top impoundment that the beavers have made with another dam.
