Story summary

The National Trust sunk three decommissioned Thames barges in the Blackwater Estuary, Essex, to create a new bird habitat.
Sediment around the barges will total 8,000 cubic meters, requiring 170 dredge trips.
The barges, ranging from 20 to 32 meters, will support various bird species, including vulnerable seabirds.
The project aims to provide a refuge above high tides, reduce saltmarsh erosion, and add 0.55 hectares of habitat.
