Appendix 1: County Wildlife Sites within Downham Market Group of IDBs area

County Wildlife Sites are areas of land that represent the best examples of semi-natural vegetation outside of Sites of Special Scientific Interest (SSSIs) and which complement SSSIs and nature reserves by contributing to ecological networks across the county.

Many support locally- and nationally-threatened habitats and species, as well as Biodiversity Action Plan priorities.
