What happened: Soil excavated from the Elizabeth line tunnels in London was transported to Wallasea Island in Essex, creating wetlands that now host nearly 40,000 overwintering birds.
Why it matters:
- The project supports biodiversity by providing vital habitat for large numbers of birds.
- It demonstrates sustainable reuse of construction materials benefiting both nature and local communities.
MNN Take: Using tunnel soil to build wetlands is an innovative way to repurpose excavation waste while enhancing natural habitats for wildlife.
