Crouch and Roach Estuaries (Mid-Essex Coast Phase
The Crouch and Roach Estuaries are located on the coast of south
Essex in eastern England. The River Crouch occupies a shallow
valley between two ridges of London Clay, whilst the River Roach is
set predominantly between areas of brick earth and loams with
patches of sand and gravel. The intertidal zone along the Rivers
Crouch and Roach is 'squeezed' between the sea walls along both
banks and the river channel. Unlike more extensive estuaries
elsewhere in Essex, this leaves a relatively narrow strip of tidal
mud which, nonetheless, is used by significant numbers of birds.
The site is of importance for wintering waterbirds, especially
Dark-bellied Brent Goose Branta b. bernicla.
The Crouch and Roach Estuary is an integral component of the
phased Mid-Essex Coast SPA.
