This section of the Thames Estuary is bordered by the West Thurrock and Swanscombe marshes, and would protect tidal mud, sand, shell and gravel seabeds. These unassuming habitats provide an ideal home for a range of invertebrates, which in turn are food of fish and waders. The site has been particularly recommended to protect the rare tentacled lagoon worm and its favoured habitats. This worm is scarce in the UK, and is very vulnerable to disturbance to its habitats.
Designation of this site in 2019 would provide a permanent London residence for tentacled lagoon worms and their many soft-bodied companions.
