Wensum Valley Wildlife

Towards its Western end, the proposed Northern Distributor Road passes through the Wensum Valley, the flood plain of the River Wensum and its tributry the River Tud.  The Wensum Valley is a Site of Special Scientific Interest and  European Special Area of Conservation.  The valley and its surrounding area contain 14 County Wildlife Sites.

It is home to a number of protected species including otters, just re-establishing themselves after years of conservation work, and water voles, the most rapidly declining mammal in the UK.

The following species information comes from the Biodiversity Action Plans of the Norfolk Biodiversity Partnership, which includes the Norfolk Wildlife Trust.  And, ironically, Norfolk County Council!  These can be found on their excellent web site at http://www.norfolkbiodiversity.org/.

Otters (Lutra lutra):
The otter is listed on Appendix 1 of CITES, Appendix 11 of the Bern Convention and Annexes 11 and IV of the Habitats Directive. It is protected under Schedule 5 of the Wildlife and Countryside Act 1981 and Schedule 2 of the Conservation (Natural Habitats) Regulations 1994. The European sub-species is listed as globally threatened on the International Union for Conservation of Nature and Natural Resources (IUCN) and World Conservation Monitoring Centre (WCMC) Red Data List.

Water voles (Arvicola terrestris):

It has limited legal protection in Britain through its inclusion on Schedule 5 of the Wildlife and Countryside Act 1981 (as amended) in respect of Section 9(4) only. This makes it an offence to intentionally damage or destroy or obstruct access to any structure or place which water voles use for shelter or protection, or to disturb water voles while they are using such a place.

Great Crested Newts (Triturus cristatus):
The great crested newt is listed on Annexes II and IV of the EC Habitats Directive, Appendix II of the Bern Convention, and Schedule 5 of the Wildlife and Countryside Act 1981.

Other important and vulnerable species potentially at risk from the NDR:
White clawed crayfish (Austropotamobius pallipes), classed as globally threatened by the IUCN and WCMC, and the depressed (!) river mussel (Pseudanodonta complanata), seriously threatened throughout its European range and belived vulnerabe to both pollution and the disturbance of river banks.  Also barn owls, hobbies and badgers.

Environmental Assessment:
Even NorfolkCouncil's own environmental assessment concludes that all of the routes they have proposed have "...the potential to significantly affect habitats, including those occupied by protected species."  Every possible route at the western end of the proposed road is described as having a "very large adverse impact" in terms of ecology.  Every eastern route is described as having a "large adverse impact".

The Council's response has been to omit from the lists in their consultation leaflets some of the most important species affected, notably otters and water voles, even though it is clear from the Environmental Assessment that they know they are there.  Presumably they are hoping that the public will not realise until it's too late.
