The Future of the Nature Reserve
|
Where coastal zones are 'squashed' between sea defences and land based developments, many habitats such as saltmarsh have become increasingly rare both nationally and internationally.The Nature Reserve and Seven Sisters Country Park have around 10% of the total saltmarsh area in East Sussex.
In the future as sea levels rise, we may have to allow the sea to gradually flood the lower river valley, recreating more rare habitats like saltmarsh, which is a natural flood defence. Storms now regularly cause severe damage to Cuckmere Haven sea defences (shingle bank, groynes and beach). To date this has been repaired but it may not be sustainable on a long term basis.'Managed Retreat' may be necessary.
The Nature Reserve was included in the South Downs National Park draft boundary.
