Info

The damming of rivers has created areas of open water, such as Stanford Water on the Wissey andThompson Water on a tributary of the Wissey, whilst modern gravel extraction has created newwetlands in place of more typical river valley habitats at Lackford, Lynford and south of Thetford.18
PingosPingos are ground water fed poolscreated from the thawing of periglacialice-lenses.Pingo sites are a key feature ofBreckland and support importantcommunities of aquatic invertebratesincluding Heteroptera and Coleoptera.19
