Beavers give a dam...about flooding
by Imogen Berryman
What's Going On Here?
Two beavers have been released in an Essex estate (UK) to manage flood risk naturally and improve biodiversity.
How Will They Help Manage Flood Risk?
Organised by a partnership between The Environment Agency, the Essex & Suffolk Rivers Trust and Essex Wildlife Trust partnership, the project aims to see how the beavers’ work compares to traditional flood risk management methods.
Beaver expert, Derek Gow has been working with similar trials and has found that water flows through 10x slower when a river has beaver dams to flow through.
Beavers To The Rescue?
After serious flooding in 2012, Lydbrook found itself under 4ft of water. These two Eurasian beavers have been drafted in to protect 18 homes across 13 acres of land.
The data captured will help to assess the success of this sustainable flood risk management approach. If it reduced flooding like similar trials have shown, there could be an opportunity to replace traditional ‘hard engineering’ approaches more widely which would beaver-y good!
The Beavers will be stars of their own wildlife documentary being screened next year where you can follow the progress and see how it worked. In the meantime, you can follow the project here.
