Book excerpt: The setting-up of the Pan-European Network is one of the main objectives of the Pan-European Biological and Landscape Diversity Strategy. The Pan-European Biological Network is intended to ensure that ecosystems, habitats, populations of species and landscapes of European importance are maintained in a good state of conservation. It aims to restore the biodiversity which is seriously endangered in Europe. Water-courses and the environments associated with them are natural corridors used by both animal species and humans. With their great natural wealth, connecting numerous elements within the corridor, both longitudinally and laterally, they are essential elements in the constitution of the Pan-European Ecological Network.
