The largest area is of special environmental and scientific interest, Chafford Gorges Nature Park; its management was taken over by Essex Wildlife Trust on 9 June 2005, since which it has a visitor centre open to the public.
In 2012, the site has been reclaimed for community and environmental use in a project involving The Cory Environmental Trust, DP World port, and the Essex Wildlife Trust working together to create the Thurrock Thameside Nature Park.
