[2] The Berney Marshes and Breydon Water habitats are being managed by the RSPB to benefit all of the wildlife in the area but in particular the breeding and wintering birds.

The area managed by the RSPB extends to 550 hectares (1,400 acres) of improved wet grassland and in winter the total numbers of wildfowl and waders can reach 85,000.

Species the reserve is important for include pink-footed goose, Eurasian wigeon and black-tailed godwit.

The water levels are kept high into the Spring so that the grasslands are in a good condition for breeding common redshank and Northern lapwing, this being helped by the grazing of cattle which helps to make the grassland sward more suitable for breeding waders.

In addition, the RSPB manage 375 hectares (930 acres) of intertidal mud flats as a sanctuary for the wintering birds.
