Dee Estuary/ Aber Dyfrdwy SAC
This site is in the north-west of the UK. It is an important area for saltmarsh and mudflats. Several types of fish, including sea and river lampreys, swim through this site.
MPA TypeSpecial Area of Conservation
Special Areas of Conservation (SACs) are strictly protected sites designated under European legislation. They contribute both to the UK MPA network and set up to protect habitat types and species considered to be most in need of conservation at a European level (excluding birds).

Surface Area158.16 km2 (61.06 mi.2)
Perimeter149.71 km (93.02 mi.)
Atlantic salt meadows (Glauco-Puccinellietalia maritimae)
Areas with specially adapted plants found in the upper reaches of saltmarshes that are not always reached by the tide. The habitat is used for grazing, but is also very important for birds.
The downstream part of a river, where it nears the sea, which is influenced by the tide These complex habitats can include areas always submerged by the tide as well as those exposed at low tide. They can be exceptionally important feeding and breeding ar
- Intertidal mudflats and sandflats (Mudflats and sandflats not covered by seawater at low tide)
Glasswort and other annuals colonising mud and sand (Salicornia and other annuals colonising mud and sand)
Specialised plants able to thrive in the lower reaches of saltmarshes where the vegetation is frequently flooded by the tide. It is important as it can help the development of more stable saltmarsh.
Annual vegetation of drift lines
Plants that last mostly only for one growing season on fine shingle shorelines that tend to shift and change.
