Rainham Marshes Nature Reserve

'One of very few ancient landscapes remaining in London, these medieval marshes right next to the River Thames were closed to the public for over 100 years and used as a military firing range. We managed to acquire the site in 2000 and set about transforming it into an important place for nature and a great place for people to visit. Now you can expect to see breeding wading birds in spring and summer, and large flocks of wild ducks in winter. Birds of prey and rare birds are regularly seen too. There are also water voles in the ditches and rare dragonflies flit across the boardwalks.'
