My hon. Friend makes an important point, which just goes to show how committed farmers and landowners are to improving and enhancing the natural environment in whatever way they can. The flow of water can have a significant impact on nature, and not only in landlocked areas. Members with coastal constituencies will be aware of saltmarsh and intertidal habitats that are critical for the conservation of many special species. I agree with my hon. Friend and support the work going on in Somerset.
