This art/science collaboration between artist Loraine Leeson and biophysical chemist Nithin Rai aims to support biodiversity on the River Thames. Reed beds are being constructed along the hull of the Tamesis Dock barge, situated opposite Tate Britain between Lambeth and Vauxhall bridges, the site of the original Lambeth Marshes. The initiative promotes the ‘greening’ of the shored up banks of the river, while providing a sheltered habitat and monitoring station for river organisms. It will also serve as a pilot for how biodiversity conservation may be expanded along the inner city reaches of urban rivers. Visitors will be able to connect to the project web site via their phones to observe recent activity and learn about the issues affecting biodiversity conservation in the Thames. Watch out in September for images of these organisms projected along the embankment. The work has been funded by the Western Riverside Environmental Fund, which re-directs revenue from landfill tax for environmental purposes.
