In spite of a wide variety of human activities, Lake Constance has preserved a natural landscape with rich biological diversity. About 200,000 water birds rest or hibernate in the region. These include about 80,000 Tufted Ducks, 50,000 Pochards, and 7,000 Great Crested Grebes. The water of Lake Constance is teeming with fish - 26 different species live there.

Partner of Living Lakes is Bodensee-Stiftung, an international foundation for nature and culture. Together with the Environmental Lake Constance Council (Umweltrat Bodensee) the Bodensee-Stiftung provides a platform for all associations aiming at sustainable development at the same time preserving its actual natural and cultural landscape. The Council comprises about 20 nature protection associations from Switzerland, Austria and Germany. The main stress is put on "Sustainable Tourism", "Organic Farming" and "Renewable Energies" e.g. solar technology for water sport.
