And here is a picture at low tide.
The mudflats at Tollesbury are quite well known. A few years ago the sea wall was broken and the land flooded as an experiment to create natural flood plains. It has worked quite well, but is still constantly monitored by DEFRA to see if this method of flood defence can be rolled out elsewhere. They had thought that a lot of the natural habitat and subsequently the seabirds would return once the land was flooded, however the ragworms had other ideas and they have thrived in the marshes. So if you need bait as a fisherman, Tollesbury is the place to be. That said, we do have a good amount of different birds around that entertain us for hours. We also have samphire all around us, which people pay an absolute fortune for. Can't see why though, personally I think it's horrible!
