Save our chalk streams
The majority of the world’s chalk streams – around 85% – are found in England, and approximately 10% of these are found in Norfolk, which makes the county globally important for this rare habitat. Of the 220+ chalk streams found in England, only 11 of these have any legal protections.
Chalk rivers in Norfolk include the Rivers Bure, Glaven, Stiffkey, Burn, Heacham and Gaywood, but the longest, biggest and most significant is the River Wensum, which runs through Norfolk Wildlife Trust’s Sweet Briar Marshes nature reserve and forms a vitally important corridor that helps wildlife to move through the county.
The Government has a valuable opportunity to stand up for our chalk streams in their planning policy reforms. We are calling on them to introduce specific legal protections in planning for all our chalk streams, to protect them from development-related harm.
Our chalk streams need protecting
England's chalk streams are one of the rarest habitats on earth! Their crystal-clear waters are home to water voles, white-clawed crayfish, Norfolk hawker dragonflies and kingfishers, making them our equivalent to the Great Barrier Reef or the Amazon Rainforest. A truly special habitat that we are so lucky to enjoy.
They are not just important in their own right, they are fabulous corridors for wildlife for creatures such as otters, birds, bats – helping these creatures to move through the landscape. Yet many of our chalk streams are now dirty and choked by pollution, threatening the wildlife that calls them home and the people that rely on them for their wellbeing. The Government must introduce specific protections for all chalk streams in their planning reforms, to ensure these unique habitats are conserved and put into recovery for future generations.
How can planning reform protect our chalk streams?
The Government is in the process of reviewing their National Planning Policy Framework (NPPF). The National Planning Policy Framework (NPPF) is a set of planning policies, which informs the preparation of local plans and decisions on planning applications. Current measures fall far short of what is required to sufficiently protect chalk streams, especially from indirect pressures, such as pollution that occurs elsewhere in a river’s catchment, or abstraction to provide a water supply for new housing. Granting chalk streams better protections within this Framework and legally recognising how important they are will mean they are better protected when road or house building happens near them.
What is NWT doing?
NWT signed an open letter to Deputy Prime Minister and Secretary of State for Housing, Communities and Local Government The Rt Hon Angela Rayner MP in November 2024. We are also contacting and meeting with Norfolk MPs to encourage them to champion chalk streams in Government during the NPPF reviews. Within the Framework, we are calling for stronger protections for chalk streams as an irreplaceable habitat, and the introduction of 50-100 metre ‘no development’ buffers surrounding chalk streams and their catchments.
We are also promoting the recognition of chalk rivers in Norfolk County Council's Local Nature Recovery Strategy and working with partners to develop projects to protect and restore Norfolk’s chalk rivers, particularly the Tas, which forms a wild corridor through the south Norfolk Claylands.
