Colne Estuary National Nature Reserve

Recommended by Visit England Logo
Overview
The Colne Estuary NNR is a large and important reserve at the mouth of the Colne Estuary and consists of the grazing marshes of Brightlingsea, the intertidal mudflats of East Mersea Flats, and the salt marsh and shingle of Colne Point. The extensive ancient grazing marshes at Brightlingsea are covered with large anthills of the yellow meadow ant – an indication that the land hasn’t been ploughed for a very long time. Today, about 100 cattle graze on the marshes for most of the summer. East Mersea Flats is an important area for waders and waterfowl, especially as a feeding ground in winter, when there are significant populations of grey plover, black-tailed godwit, dunlin, sanderling and turnstone, and waterfowl such as Brent geese and widgeon. Colne Point’s salt marsh and shingle also attracts a wide variety of birdlife, and is an important area for breeding birds. In summer, these include ringed plovers, oystercatchers and the nationally rare little tern.
