Thames estuary conservation

In the last 30 years, the Thames Estuary has become one of the world's most unpolluted metropolitan tideways, but its rich variety of wildlife remains a well kept secret.

Commercially important fish species such as Dover sole and sea bass use the Thames as spawning and nursery grounds. The estuary's mud flats provide an essential feeding ground for the internationally important migrant bird populations and recent research, carried out by ZSL, has also confirmed that dolphins, porpoises and seals are all regular visitors to the Thames.

ZSL has a number of Thames Estuary Projects, falling under the Marine and Freshwater conservation programme, that study the Thames and it's diverse ecology.
