Harbour mud being used in project to restore precious saltmarsh

DREDGED mud from a harbour on the south coast is being used to restore surrounding saltmarsh, in an innovative scheme to protect the local economy and wildlife.

The team behind the scheme to restore the eroding saltmarsh that protects Lymington Harbour, Hampshire, hope the “remarkable” recovery of natural habitat could be replicated around the country to conserve coastal areas at risk from rising sea levels.

Lymington has a ferry link to the Isle of Wight, 1,600 leisure moorings and sees 20,000 visiting yachts a year, with the harbour worth tens of millions of pounds a year to the local economy.

But its precious saltmarsh is eroding at a rate of two or three metres a year in the face of rising seas and increased storminess driven by climate change, which risks leaving the harbour exposed and unviable.

Building rocky breakwaters and dumping dredged mud in front of the saltmarsh have been used in recent years to slow the erosion.
