Chalk streams are a characteristic and wonderful 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, of the 200 or so chalk streams in the world, over 160 are found in England. Chalk streams are a naturally rich habitat, capable of supporting many different plants and animals. To be in a position to restore and conserve one of these precious ecosystems is a thrill and a privilege.
