The Site is a very shallow arm of a fjord featuring extensive beds of submerged vegetation and large mudflats which are exposed at low tide. The bay is surrounded by salt marshes, wet grassland and agricultural land. The Site’s wealth of mussels, snails and invertebrates supports a wide range of birds. It is one of the most important wetlands in the region for staging migratory waterbirds, particularly ducks and waders, and it is also important as a breeding, moulting, feeding and overwintering site. It supports some globally vulnerable species such as the horned grebe (Podiceps auratus) and the velvet scoter (Melanitta fusca). The salt marshes also offer habitat to nationally threatened plants, and the Site is important for the critically endangered European eel (Anguilla anguilla). Some commercial net fishing is practiced in some of the deeper waters out in the fjord. The area functions as a sediment trap for eroded material carried along the streams flowing into the shallow waters. The Site is considered one of the best birdwatching sites in the county and facilities include an observation tower; the management authorities were planning in 2022 to produce a report on the birds observed.
