If there’s a dangerously high tide, these marshes should act like a sponge – absorbing some of the floodwater that might otherwise threaten towns and villages. It’s a way of working with mother nature, giving the sea room to breathe. So, everyone should be a winner: less threat from flooding, more salt marsh and more wildlife for us all to enjoy. In fact, coastal landscapes like these are of worldwide importance for birds. Our salt marshes, sands and mudflats provide vital winter feeding grounds for more than 6 million wildfowl and waders. It’s one of our most magnificent wildlife spectacles.
