An Eye on Eels

All is not well with the European eel (Anguilla anguilla).

Where are our wastelands?

‘Imagine you are walking through a field in summer. You might think you were in the heart of the country, but you could equally be in the middle of London where urban wastelands … previously developed land that has been abandoned by people and reclaimed by nature … bring people closer to nature.’ ‘Brownfield? Greenfield?’ London Wildlife Trust and the London Brownfields Forum, 2002.
