Peter, The harbour conservancy are running an initiative called CHAPRON to protect and recover nature. Not sure how successful it will be, but there is plenty of info on the conservancy Web site.
As I look at the photo again, I note how much more in tact the wrecked barge is outside the mill. Also the mature elm trees along the shore towards Warblington.
