Why Protect It?
-
-
Over 40 habitat categories have been identified e.g. heathland, freshwater ponds, saltmarsh etc
Rock Groyne
-
As they last longer than timber (wooden) groynes and they are vital in preventing the longshore drift occuring in the area, so the beach remains in place
Beach Nourishment
Since the mid 70's, beach nourishment has been a method used to add material to beaches in this area
-
-
-
Gabion Cages
-
The cages protect the headland as they take the power out of the waves so the impact of erosion is not as severe
-
Long Groyne
The groyne was constructed betwen 1937 - 1939 and is critical to controlling coastal erosion in Poole and Christchurch Bays
-
-
So successful that the sea never reaches the base of the cliff even in storms, and a dune ecosystem has developed
Without the long groyne, beach material would rapidly wash away and the cliffs could start to erode again within a year
The repair and upgrade of the groyne will take place from 2021 - part of a £33 million project from 2021 - 2031
The groyne will be raised in height to help provide protection for the next 100 years from predicted sea-level rise
-
Conflicts
Sand dredging for beach nourishment from the near Isle of Wight is causing conflcit as this can cause more erosion locally to the IoW
Conflict with the local people in the rest of the area in Christchurch Bay that are not being as well protected e.g Barton on Sea
Barton on Sea
Further round the coast at Barton on Sea, they are being starved of material and the beaches are disappearing - any longshore drift that should bring in replenishment of sand is being caught at Hengistbury Head and Mudeford Spit
-
The local people there are not happy that their area is falling into the sea and not being protected as much - house prices are rapidly decreasing because of this
