Bradwell Cockle Spit on the Dengie Peninsular consists of some 30 acres of shell bank together with extensive saltmarsh. The spit has been built up by tidal currents and is mainly cockle and oyster shells. During bad weather and strong tides, the spit moves and in the past two decades, up to 100 metres of saltmarsh has been lost to erosion.
