In a pioneering project hailed as a first of its kind in the UK, the National Trust has submerged retired Thames barges in an estuary to combat erosion and establish a novel “island” habitat for avian species.
The initiative involves the sinking of three decommissioned lighters – historical barges formerly utilized for transporting coal and other industrial materials – within the Blackwater Estuary, situated between Maldon and West Mersea in Essex.
These barges have been strategically filled and overlaid with sediment, effectively creating a new island sanctuary for birds, including the endangered dunlin, curlew, ringed plover, and lapwing.
The National Trust characterizes this endeavor as one of several “innovative, nature-based solutions designed to safeguard Northey Island against the impacts of rising sea levels and the accelerated loss of saltmarsh ecosystems.”
The historic barges, once integral to the transportation of building materials, coal, and food from the Port of London, had been moored in Essex for over three decades.
Now positioned on the intertidal mudflats of the estuary, these vessels have forged a new landmass along the edge of the existing saltmarsh at Northey Island.
These barges have been repurposed to bolster efforts aimed at securing the future of endangered seabirds currently listed on the UK red list for conservation.
The newly formed island is also anticipated to play a vital role in mitigating erosion of the saltmarsh habitat, which faces a significant threat from rising sea levels at the neighboring Northey Island, according to the National Trust.
The National Trust has lauded this project as “a bold marine engineering feat,” showcasing an innovative approach to conservation.
Katy Gilchrist, coastal project manager for the Trust, stated: “This is the ultimate act of marine recycling – transforming retired industrial vessels into a sanctuary for wildlife.”
“We’re basically turning history into habitat, and as far as we know, no-one has attempted anything quite like this before.”
The barges, ranging in length from 20 to 32 meters (66 to 105ft), underwent thorough cleaning and were rendered seaworthy before being towed into position and carefully placed onto a pre-constructed platform of sediment.
Holes were strategically cut into the hulls to facilitate the sinking of the vessels, which were then filled with sediment, primarily mud, to ensure they were adequately weighed down and securely anchored.
“Once the island is fully established with gravel on top, it will sit safely above the highest tides to offer a safe refuge for some of our bird species which are in decline,” Gilchrist said.
Upon completion, the island will contribute 0.55 hectares (1.4 acres) of new habitat – nearly the size of a football pitch – within the Blackwater Estuary.
Matt Wilson, countryside manager for the National Trust, commented: “The new island, located just off the eastern shore of Northey will provide a refuge for birds above the highest tides and away from disturbance on shore, acting as a lifeline for birds that are running out of safe spaces to nest and rest.”
“As well as creating a new habitat for birds, the island will also help to reduce erosion of the existing saltmarsh at Northey Island,” he added.
The National Trust is collaborating with the Environment Agency, Natural England, Maldon Harbour Improvement Commissioners, specialist engineering and environmental consultants Royal Haskoning DHV – and specialist marine contractors Landbreach Ltd on the project.
