Somebody reminded me of this recently and knew how to get in touch with the farmer in question, so I telephoned and arranged a visit.
We walked down to the bank of the river and soon found plenty of signs of activity from the winter. We didn't see any really recent gnawing (such as from the previous night), but there was some that could have happened in the last week or so.
What is clear in this photograph is that we are looking at coppicing activity that comes from at least Spring 2009.
A really interesting sight was the coppicing of willow, carried out during times of flood high up the trees. You can see, at between roughly half past one and two-o'clock from Louise's head, branches that have been gnawed and then put out new shoots.
This picture shows the same two nodes of shoots from closer.
