An inland tidal estuary with extensive areas of mudflats exposed at low tide. The site is internationally important for wintering waterbirds, notably Bewick's Swan, Cygnus columbianus bewickii, and it supports important numbers of passage birds. Human activities include recreation, hunting, and agriculture. Extended in March 2000 from 515 to 1203 ha.
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!
