Annex I habitats that are a primary reason for selection of this site

Annex I habitats present as a qualifying feature, but not a primary reason for selection of this site

  • Not Applicable

Annex II species that are a primary reason for selection of this site

  • 1092 White-clawed (or Atlantic stream) crayfish Austropotamobius pallipes

    The Wensum is a chalk-fed river in eastern England, and is an eastern example of riverine white-clawed crayfish Austropotamobius pallipes populations. As with most of the remaining crayfish populations in the south and east of England, the threats from non-native crayfish species and crayfish plague are severe. Designation of the river as a SAC provides as much protection as can be afforded to such vulnerable populations.
