Added to the Montreux Record, 4 July 1990. Natura 2000 (SPA, SAC) Local Nature Reserve; SSSI. The Dee is a large funnel-shaped sheltered estuary and is one of the top ten estuaries in the UK for wintering and passage waterfowl populations. The estuary supports internationally important numbers of waterfowl and waders. The estuary plays a very important role in shoreline stabilisation and dissipation of erosive forces, sediment trapping and water supply. The two shorelines of the estuary show a marked contrast between the industrialised usage of the coastal belt in Wales and residential and recreational usage in England. The site was subject of Ramsar Advisory Missions in 1993 and 1994 due to several adverse factors affecting its ecological character: pollution, overfishing, introduction of invasive species and general disturbance from transport and industrial activities. Since them, management plans have been developed and implemented. However, some of the threats remain. Ramsar site no. 298.
This site is currently under consideration for inclusion in the new UK MPA network. Having marine components does not automatically qualify a site to be part of the new MPA network. As such, the marine components of this site, as well as the management efforts, are being evaluated. Check out our MPApedia page on the UK for more information!
