It assesses the significance of every estuary and the distribution and numbers of all species ordinarily current, and by means of environment this in a world framework demonstrates the outstanding significance of the estuaries round those islands. Threats to the material of the panorama and its natural world abound, and estuaries should not exempt. Barrage schemes, business and agricultural reclamations and lots of different pressures exist and are the topic of chapters which survey the location, now and sooner or later.
