This Site of Special Scientific Interest is managed by Natural England as a National Nature Reserve. The coastline of the Wash which Sandringham borders have been designated a Special Protection Area for its importance as a wildlife haven on the tidal mudflats. In the late autumn and early winter, skeins of thousands of pink-footed geese can be seen leaving or returning to the marsh, flying directly over Sandringham.
Sandringham has been committed to maintaining the environment and the habitat to support a thriving flora and fauna, adopting sympathetic farming practices. Over five thousand trees and several miles of hedges are planted each year. The Estate also recycles food waste, glass, metals, plastic, cardboard and paper.
- Over two million trees have been planted;
- 45 new woodlands created;
- 40 kilometres of new hedges planted (including 7km in 2008 alone);
- 200 kilometres of field margins established;
- 160 hectares of wild bird cover established;
- 200 hectares of uncultivated and wildland maintained;
- 10 wetlands created;
- The management of Dersingham Bog, a Site of Special Scientific Interest, was transferred to the Nature Conservancy Council, now Natural England.
