This is described by Natural England as "both a nationally important wetland site and one of the richest areas of traditionally managed grazing marsh and dykes now remaining in Broadland". The principal conservation lies in the aquatic flora and fauna of the dykes, especially the dragonflies.{{cite web|url= https://designatedsites.naturalengland.org.uk/PDFsForWeb/Citation/1002865.pdf |title=Ludham - Potter Heigham Marshes citation|series= Sites of Special Scientific Interest|publisher=Natural England|accessdate= 12 June 2018}}
