Stretching 10 kilometres from Exeter to Exmouth and Dawlish Warren, the Exe Estuary stands as one of the most important wildlife sites in south-west England. This internationally protected wetland hosts more than 20,000 birds each winter, making it an essential destination for anyone passionate about birdwatching and coastal wildlife.
International Conservation Importance
The estuary's significance is reflected in its multiple conservation designations, including Ramsar Site status (recognising wetlands of international importance), Special Protection Area, and Site of Special Scientific Interest. These accolades confirm the Exe Estuary's vital role as both a breeding and feeding ground for thousands of birds, with over 10,000 wildfowl and 20,000 waders wintering here annually.
Recent surveys recorded a remarkable 77 different species of wetland birds, with peak totals exceeding 30,000 individual birds. Most notably, the estuary provides winter refuge for a third of the UK's entire avocet population and hosts one per cent of the world's dark-bellied Brent geese, which migrate here from the Russian Arctic.
Rich Habitats and Diverse Wildlife
The Exe Estuary's ecological richness stems from its five distinct habitat types:
Mudflats and sandflats teem with microscopic life. Just one square metre of estuary mud contains up to 10 million tiny worms, thousands of snails, and hundreds of shellfish, providing extraordinary food resources for wading birds. These intertidal areas reveal their treasures at low tide before disappearing beneath the water.
Eelgrass beds stabilise the sediment whilst offering essential habitat for fish and crustaceans. The rare eelgrass (Zostera noltii) serves as a vital food source for wigeon and Brent geese, who depend on these underwater meadows throughout winter.
Mussel beds attract oystercatchers, whose distinctive orange bills expertly prise open the shells. Saltmarshes provide high-tide roosting areas for wildfowl and waders, whilst reedbeds offer summer nesting sites for Cetti's warblers, sedge warblers, and reed warblers.
Birdwatching Throughout the Seasons
Winter transforms the Exe Estuary into a spectacular theatre of avian activity. Alongside the dark-bellied Brent geese and avocets, visitors regularly spot black-tailed godwits (with numbers increasing yearly), dunlin, oystercatchers, grey plovers, and lapwings. Duck species include wigeon, pintail, teal, shoveler, goldeneye, and red-breasted mergansers.
Waders such as redshank, curlew, greenshank, ringed plover, and sandpipers probe the mudflats, whilst little egrets (now breeding on the estuary) stalk the shallows. Rare visitors occasionally include Slavonian grebes, spoonbills, cattle egrets, and great white egrets. Peregrine falcons patrol overhead, and most winters bring the extraordinary spectacle of starling murmurations at the Exe reed beds, where thousands of birds perform synchronised acrobatic displays at dusk and dawn.
Dawlish Warren: Botanical Treasure
At the estuary's southern tip, Dawlish Warren National and Local Nature Reserve harbours remarkable botanical diversity. This sand spit supports 620 plant species, including the rare Warren crocus, found at only one other British location. Over 2,000 invertebrate species have been recorded here, including ruddy darters, hairy dragonflies, scarlet tiger moths, and Jersey tiger moths. The reserve's 583 flowering plant species and 260 fungi species make it a botanist's paradise.
