List of Sites of Special Scientific Interest in Suffolk

With an area of 1,466 square miles (3,800 km2), it is the eighth largest county in England,[1] and in mid-2016 the population was 745,000.

[3] Much of the coast consists of the estuaries of the Orwell, Stour, Alde, Deben and Blyth rivers, with large areas of wetlands and marshes.

The largest is Breckland Forest at 18,126-hectare (44,790-acre), which is partly in Norfolk and has several invertebrates on the IUCN Red List of Threatened Species,[6] and the smallest is a 0.1-hectare (0.25-acre) meadow in London Road Industrial Estate, Brandon, which has the largest known wild population in Britain of the nationally rare sunflower Artemisia campestris.

This fossiliferous site exposes rocks of the marine Red Crag Formation, with a megaripple sequence showing the gradual reduction in depth of the sea.

[105] The Red Crag spans the end of the Pliocene around 2.6 million years ago and the start of the succeeding Pleistocene.
