Cranberry Rough is an 81.1-hectare (200-acre) biological and geological Site of Special Scientific Interest in the parish of Hockham, east of Attleborough in Norfolk, England.[1][2] It is a Nature Conservation Review site, Grade 2,[3] and the Great Eastern Pingo Trail, which is a Local Nature Reserve, goes through the site. Part of it is a Geological Conservation Review site,[4] and it is part of the Breckland Special Protection Area.[5]
The area is the site of a former lake known as Hockham Mere, which was drained and dried up by the middle of the 18th century.[6] It has swamp woodland, grassland, tall fen and a network of ditches and pools, with a diverse range of wetland plants and insects, especially butterflies, dragonflies and damselflies. Large areas are covered with sphagnum mosses.[7] Its biogenic sediments contain a late-Devensian & Holocene pollen record.[8]
