Thames21, London's leading waterways charity, today launched the capital's first ‘Waterway Treasure Map' - a wiki for the waterways - to record and save the jewels of London's rivers and canals.

The charity is calling on Londoners to put their favourite sites on the map now, and help safeguard their future.

The interactive website allows users to view and add their own places of special interest, whether they are historical, wildlife viewing areas, or even a nice spot for a picnic. The map will also be used to record and help save areas under threat or in danger of being spoilt.

This valuable online resource is the first of its kind, and allows users to create the map themselves, by adding their stories, photos and links. It will be a living archive, unlocking information that is normally trapped in dusty drawers or stored away in someone's memory.

With the increasing effects of climate change, the waterways are also under pressure, and the map will be used to track invasive species like Japanese Knotweed and Himalayan Balsam that destroy riverbanks. Spots that are troubled by rubbish and fly-tipping can also be reported on the site.

With support from the Heritage Lottery Fund, the project will initially be running in four London boroughs: Southwark, Ealing, Lewisham and Hounslow, before eventually being rolled out across all London areas.

Mayor of London, Boris Johnson said: "This is a fantastic new way to celebrate and help protect our precious waterways by sharing their own unique experiences online. I urge Londoners to get involved and help form a virtual encyclopaedia about these wonderful natural assets."

Chief Executive of Thames21and London Leader Debbie Leach said: "Turning detective for Thames21 will provide people with a great new way of volunteering. People of all ages and interests will have a chance to get involved, get out and about exploring London's rivers and canals and help create the map with their discoveries."

Sue Bowers, Head of the Heritage Lottery Fund said: "Our support for this invaluable project will help to raise community awareness amongst Londoners of their local canals and waterways, enabling them to develop a sense of pride and ownership in the natural heritage environment around them."

This project forms a major new part of Thames21's outreach work to connect Londoners with the capital's rich network of waterways. The project will highlight the unique history, character and biodiversity of London's rivers and canals, which have shaped the city over centuries influencing trade, commerce and tourism.
