England's Rare Chalk Streams Need Urgent Protection
8 Mar
Summary
- Chalk streams, a rare freshwater habitat, are predominantly found in England.
- Environmental groups are urging for greater legal protection for these unique streams.
- Government and water companies are investing in reforms and upgrades to clean up streams.
England's chalk streams, one of the world's rarest freshwater habitats, are facing calls for enhanced protection from environmental campaigners. These unique ecosystems, originating from porous chalk bedrock, are known for their exceptionally clear water and gravelly bottoms. The vast majority of the 220 existing chalk streams are located in southern England.
The London Wildlife Trust is advocating for chalk streams to be categorized alongside other irreplaceable habitats like ancient woodland within the National Planning Policy Framework. They argue that current legal protections are insufficient for these invaluable natural resources.
In response, the Department for Environment, Food and Rural Affairs (Defra) has announced a "once-in-a-generation" reform of the water industry, including immediate actions to cleanse chalk streams. A significant investment of £2 billion in water company projects over five years is earmarked for chalk stream restoration and abstraction licensing system upgrades.
Water companies like Thames Water are undertaking substantial upgrades to their wastewater networks. These improvements aim to increase treatment capacity, reduce storm discharges, and implement new nutrient-reduction schemes. Efforts are also underway to improve specific urban rivers, such as the River Wandle, through projects like fish-pass enhancements.
