roughly 8 metre high external dikes that run for almost 30 kilometers right around this island in the wotton sea. but internal tykes also help to protect the island. as do the drainage channels. because it's not only the north sea waters that pose a threat but also those that rain down from above so how do the locals get the water off their island they channel excess water into a basin by the harbor where the from there it's pumped out into the sea at low tide it's a solid system except during periods of extremely heavy rainfall. increasing rainfall and rising sea levels will be challenges for a pair of arm but as a tide marker in the harbor shows the islanders have plenty of experience with tidal surges they've done battle with the sea on many occasions. nevertheless the local population can no long. ungar rely on the exact same type construction that has served them in the past. zor the state of came up with a strategy it's called the climate dike investment q i wonder because the 1st we're factoring in climate change and are currently strengthening our dikes and such a way that we can build t

apply a process known as beach replenishment that would see sand added to certain areas of the wotton sea pilot projects will determine whether it will work. also impacted by climate change is the buffer zone between the sea and protective dikes these salt marshes are important for coastal protection because they serve to break the force of the waves before they crash against the levees the only plants that grow here have to withstand high concentrations of salt but as i know bush adding of the wind and sea conservation station explains the marshes are also home to birds and plenty of insects and this is a stem swelling from a sea planting stem warning weevil are it does nothing else in the world besides laid eggs in the flower stalks of c. plant st and its groups develop here in this stem. there's also a c. planting stem boring we've all parasitic wasp. salt marshes grow when sediment is deposited on them during high tide but for how much longer than. i moment salt marshes are keeping up a lot of sea levels rise more quickly there will be a tipping point where they disappear because they

and migratory and mudflap birds estimates just there are some 10000 species in the wotton sea. obviously the water and see in terms of its size and biodiversity is pretty unique water is why it became a world heritage site but there are landscapes such as islands mudflats and salt marshes in many other places around the world the experience we collect here in terms of sea level rise can also be transferred to other regions. it's hard to predict the exact future of the mudflats today it's proving difficult to find one prominent if elusive inhabitant the loved one. them but they didn't have any luck finding a loved one but he has found something else a razor clowne. i was lucky enough to see one on a different tour of the mud flats extremely rare to see want to tall because they can stand up within seconds it's pretty fascinating and then they lie flat and then this foot comes out 6 out from the ground and then the muscle flips upright and burrows its way into the moat. the warden sea is a fascinating place an eco system that might one day disappear beneath the waves forever. aba
