Chalk streams are a characteristic and attractive feature of the Chilterns landscape. They are also a globally rare habitat, confined to north west Europe and to the UK in particular. In fact more than 85% of all the chalk streams in the world, are found in England.
Chalk streams are important habitats for wildlife and support a massive range of plants and animals. They are home to some of our most threatened plants and animals, such as the water vole and brown trout. They also have a fascinating history and supported many thriving industries in the past.
The Chilterns’ chalk streams are so important that a special partnership project has been created to conserve them. Uniting all the organisations with an interest in the streams, the Chilterns Chalk Streams Project works with local people across the Chilterns to improve river habitats, improve access and enjoyment and promote the sustainable use of water.
