List of Sites of Special Scientific Interest in Suffolk

View over a pond from a bird hide at Lackford Lakes

The following is a list of Sites of Special Scientific Interest (SSSIs) in Suffolk, England. In England the body responsible for designating SSSIs is Natural England, which chooses a site because of its fauna, flora, geological or physiographical features.^[1]

As of January 2013 there were 141 SSSIs within Suffolk.^[2] Sites include ones also designated as Ramsar Sites, ancient monuments, areas of Heritage Coast, National Nature Reserves and European special protection areas. Management is carried out locally, including by the National Trust, Ministry of Defence, RSPB and Suffolk Wildlife Trust as well as by local landowners.

Sites range from the very small, with Waldringfield Pit being just 0.08 hectares (0.2 acres) in area, to two of the largest SSSI in England in the Breckland Farmland and Breckland Forest areas, both of which are larger than 10,000 hectares (24,711 acres) in area and cross the border into Norfolk.

For other counties, see List of SSSIs by Area of Search.

The data in the table is taken from English Nature's website in the form of citation sheets for each SSSI.^[3]
