Bishop of Norwich Backs UNESCO World Heritage Status for England's Rare Chalk Streams

The Rt Revd Graham Usher, Bishop of Norwich and the Church of England's lead bishop for the environment, has thrown his support behind a new parliamentary bill seeking UNESCO World Heritage status for England's chalk streams.

The Chalk Streams (UNESCO Natural World Heritage Site) Bill was introduced to Parliament on 25 February 2026. It would require the Secretary of State to secure global heritage recognition for these rare waterways.

Only around 200 chalk streams are known to exist worldwide, and approximately 85 per cent of them are located in England. Many of these flow through the Diocese of Norwich, including the Babingly, Glaven, Gadder, Ingol, Hun, Stiffkey, Tiffey, Wissey and Wensum.

People are rightly horrified by the destruction of rainforests thousands of miles away but sometimes seem less concerned about collapsing ecosystems almost literally on our doorstep.

Bishop Graham Usher said in support of the campaign.

These crystal clear waterways support more species of plants than any other English river type and provide vital habitat for threatened wildlife including water voles, brown trout, southern damselflies, white clawed crayfish and Atlantic salmon.

However, most chalk streams are in poor condition. Over abstraction is causing some to run dry in summer months, while sewage discharges, agricultural pollution and climate change place increasing pressure on these fragile ecosystems. Fewer than a dozen currently have Site of Special Scientific Interest (SSSI) protection.

Bishop Usher, who also serves as the Anglican Communion's lead bishop for biodiversity, previously attempted to protect chalk streams through an amendment to the Planning and Infrastructure Bill. The amendment passed the House of Lords with a 196 to 137 vote but was ultimately defeated in the House of Commons.

Christians are called to advocate for God's creation. In our nature impoverished land, this means protecting our heritage of natural wonders.

Bishop Usher declared.

The campaign also calls for chalk streams to receive planning protection by listing them alongside ancient woodland, and for water company fines to be reinvested into chalk stream restoration. Bishop Usher was recently named to the "edie 100" list of UK sustainability and climate leaders, with the recognition acknowledging everyone in the Church of England working to protect the natural world.

The Crusader's Opinion

God gave us dominion over the earth not to destroy it, but to steward it. When 85 per cent of the world's rarest river habitat sits in your backyard and you let it be poisoned by sewage and sucked dry by greed, that is not progress. That is negligence before the Creator. Bishop Usher is right to stand in Parliament and demand action. These chalk streams are not just ecological wonders; they are part of the heritage of a Christian nation that once understood its duty to protect what God entrusted to it. The fact that the House of Commons voted this down should shame every MP who cast that vote.
