Colne Estuary, Protected wetland estuary in Essex, England
The Colne Estuary contains five tidal arms flowing into the main river channel, featuring mudflats, saltmarsh, grazing marsh, and sand spits across 2,701 hectares.
The geological formations at East Mersea contain significant Pleistocene deposits that demonstrate climate patterns from post-Anglian interglacial periods.
The Essex Wildlife Trust manages three distinct areas within the estuary: Colne Point, Fingringhoe Wick, and Howlands Marsh for conservation and education.
Visitors can access designated observation points and public footpaths throughout the estuary while maintaining distance from protected wildlife zones.
The peat seam in St Osyth Marsh, dated to 4280 BP, provides crucial information about historical saltmarsh development and coastal changes.
