The feeder streams
The Salcombe-Kingsbridge estuary is unusual because it has no large river feeding it – just a series of small streams from Frogmore, Bowcombe, Batson, East Allington, Sherford and other surrounding villages, rising at springs some 140 metres above sea level.
The estuary
The Salcombe-Kingsbridge estuary is tidal up as far as Kingsbridge, the bridging point 5 miles inland. Like the other estuaries of South Devon, the original deep river valley has been inundated by later sea level rise, with the tide flooding in to create a wide expanse of water.
Designations
As well as being part of the AONB, the estuary is also a Site of Special Scientific Interest and a Local Nature Reserve and lies within the South Devon Heritage Coast.
Wildlife
Two tides a day fill this ‘ria’ or drowned river valley with sea water. With no river input the estuary is almost entirely a marine system which has brought about some rare and important habitats and species. Reed beds, mudflats and eelgrass beds all help to support the abundance of wildlife that inhabits Salcombe-Kingsbridge estuary. The expansive mudflats in its upper regions contain a huge abundance of worms, snails and bacteria, which in turn provide an important food source for wading birds and fish populations within the estuary. The lower fringe of the foreshore is inhabited by eelgrass providing a nursery habitat for fish and seahorses. The Salcombe-Kingsbridge estuary is also home to species of crab, shellfish, otters and it is not uncommon to see dolphins, seals and basking sharks venturing into the estuary to feed.

Caring for the estuary
The lack of a true river input mean the water catchment area of the Salcombe-Kingsbridge estuary is relatively small and short for an estuary of its size. The Salcombe-Kingsbridge estuary is affected by both-point source pollution (that with a traceable source into the estuary) and diffuse pollution (from the land or atmosphere). Pollutants can make their way quickly into the water and be highly toxic killing wildlife within the Salcombe-Kingsbridge. They can also reduce the oxygen content and water quality of the estuary potentially leading to ‘anoxic dead zones’. It is important that we understand how our actions can affect the estuary and what we can do to prevent them.
Blue Carbon
Our coast and estuaries play an important role in the binding of the worlds biological carbon (or green carbon), with more than half being captured my marine living organisms (hence it is called blue carbon). With such an important carbon fixing resource on our doorstep it is important that we restore and maintain healthy marine ecosystems. For further details pleas access the full blue carbon report.
