Chalk streams are a characteristic and attractive feature of the Chilterns landscape. They are also a globally rare habitat. In fact there are only 283 chalk streams in the UK, and the UK accounts for around 85% of the global total.

Chalk streams are important habitats for wildlife and support a massive range of species. 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.

Our three films provide an excellent overview, explaining ‘What are chalk streams, and why are they special‘, How chalk streams work, and exploring the threats they face.

The nine 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.
