Technical water management measures in the inundation region of southern Moravia significantly affected conditions of terrestrial and water ecosystems. Changes in ecological conditions and reaction of biota in the ecosystems of floodplain forests and meadows and regulated watercourses and retention reservoirs were studied within the UNESCO Man and the Biosphere programme for several years by a multi-disciplinary team of scientific workers. A broad extent of knowledge from many scientific disciplines enables a deeper insight into complexity of ecological relations after an intervention into landscape to ecologists, water managers, foresters, agronomists and biologists of different specializations.
