context_page_description: Cley Marshes is a 176-hectare nature reserve on the North Sea coast of England just outside the village of Cley next the Sea, Norfolk. A reserve since 1926, it is the oldest of the reserves belonging to the Norfolk Wildlife Trust, which is itself the oldest county Wildlife Trust in the United Kingdom. Cley Marshes protects an area of reed beds, freshwater marsh, pools and wet meadows and is part of the North Norfolk Coast Site of Special Scientific Interest, Special Area of Conservation, Special Protection Area, and Ramsar Site due to the large numbers of birds it attracts.
  The reserve is important for some scarce breeding species, such as pied avocets on the islands, and western marsh harriers, Eurasian bitterns and bearded reedlings in the reeds, and is also a major migration stopoff and wintering site. There are also several nationally or locally scarce invertebrates and plants specialised for this coastal habitat. It has five bird hides and an environmentally friendly visitor centre and further expansion is planned through the acquisition of neighbouring land and improvements to visitor facilities.
context_section_description: Water voles are a highly threatened species in the UK, with a huge decline in numbers of 70–90%, mainly due to predation by the introduced American mink, but also habitat loss and water pollution. They are still common at Cley, which is one of a number of East Anglian sites now of national importance for this species. Brown hares are widespread, and European otters may be seen, with spraints regularly found at the southern end of East Bank. The common frog, common toad and common lizard all occur on the reserve.
  Arnold's Marsh and the other lagoons nearest the beach are salty due to the percolation of seawater through the shingle bank. These saline lagoons may cover mud, firm sand or submerged vegetation, and hold some rare and threatened invertebrates including starlet sea anemone, lagoon sand shrimp, Atlantic ditch shrimp, the mysid shrimps Paramysis nouveli and Neomysis integer, lagoon cockle, the bug Orthotylus rubidus and spire snail. Little whirlpool ramshorn snail has been found in a freshwater channel. Rare beetles associated with these coastal environments include yellow pogonus, Bembidion ephippium and Tachys scutellaris. These marshes are the only reliable UK site for the Pogonus species, and even here it is localised and hard to find.
