SSSIs are the country's very best wildlife and geographical sites. They include some of the most spectacular and beautiful habitats; wetlands teeming with wading birds, winding chalk rivers, flower-rich meadows, windswept shingle beaches and remote upland peat bogs.
There are over 4,000 Sites of Special Scientific Interest (SSSIs) in England, covering around 7% of the country's land area. More than 70% of these sites, (by area) are internationally important for their wildlife, and designated as Special Areas of Conservation (SACs), Special Protection Areas (SPAs) or Ramsar sites. Many SSSIs are also National Nature Reserves (NNRs) or Local Nature Reserves (LNRs).
