Since the beavers discovered the beech trees on the estate of Kasteel Amerongen, one tree has already been completely gnawed. Almost all other trees have now also been gnawed. That can be problematic: if the sap flow is interrupted, the tree dies. Addressing the problem is tricky because beavers are a protected species.
