Site description This IBA lies in the Severn Vale, about 10 km south-west of Gloucester, in an area subject to winter flooding. A network of ditches that support aquatic and marginal plants separates grass fields, which hold small numbers of breeding waders. Part of the site is common land. The site is important for wintering wildfowl and waders.
