Breckland in Norfolk and Suffolk is a 39,433 hectare Special Protection Area (SPA) under the European Union Directive on the Conservation of Wild Birds. The SPA partly overlaps the 7,544 hectare Breckland Special Area of Conservation. As a landscape region it is an unusual natural habitat of England. It comprises the gorse-covered sandy heath that lies mostly in the south of the county of Norfolk but also in the north of Suffolk. An area of considerable interest for its unusual flora and fauna, it lies to the east of another unusual habitat, the Fens, and to the south west of the Broads. The typical tree of this area is the Scots pine. Breckland is one of the driest areas in England.

Thetford Forest is the largest lowland pine forest in Britain and is located in a region straddling the north of Suffolk and the south of Norfolk in England. It covers over 19,000 ha in the form of a Site of Special Scientific Interest.
