A project to restore sand dunes in Lancashire has been hailed a success by conservationists.

Over the last 150 years, more than 80% of the sand dunes in Lytham St Annes have been lost to make way for housing and roads.

The Fylde Sand Dunes Project has been boosted by using Christmas trees and planting marram grass to bring up to 328 ft (100m) of sand dunes back to the area, said Amy Pennington, of Lancashire Wildlife Trust.
