In Poland, EIA and SEA have been integrated into the planning system in a different way compared to Germany. There, EIA is performed within an independent procedure. For projects mandatorily requiring EIA, the respective county decides on the outcome of an EIA, whereas for projects with case-by-case screening the regional authority's council is responsible for this task. There are still significant uncertainties in the application of SEA which sometimes leads to conflicts with the EU provisions. In Poland, provisions for SEA were already made in the year 2000. Different SEA procedures are established for regional plans and for other environmental plans. Furthermore, in April 2004, provisions for the EA according to the Habitats Directive were made in the Polish nature protection act. EA according to the Habitats Directive is strongly linked to EIA and SEA. Poland is already experienced in the practice of EIA and SEA. However, there still is a lack of methodological guidelines. Furthermore, the different legal provisions and procedures need to be further adjusted to each other.
Summary Possibilities of Co-Operation between Nature Conservation and Water Management. The EU Water Framework Directive (WFD) issued different regulations in the context of flodplains although not listing them directly as target areas to be dealt with. This makes clear that flodplains are assed as functional areas and therefore also need concrete requirements for their protection and development from a water management point of view. Additionally measures along rivers and streams necessary to reach the environmental aims of the WFD can result in changed conditions in floodplains. This is illustrated by examples of the Lower HAvel River. This may lead to conflicts with the aims and tasks of nature conservation. Particularly the definition of development aims needs an early identification of agreements and possible conflicts. Therefore the water management authorities have to consider the influence of the floodplains on the condition of the water bodies in an early stage: as soon as reference conditions are described, for the assessment of the risks to achieve the environmental aims as well as for the development of measurement programmes. Further it will be the task of nature conservation institutions to establish own target systems for the water bodies additionally to the NATURA2000- syetem of protection areas as well as for the development of measurement programmes of the WFD. Zusmamenfassung Die EU- Wasserrahmenrichtlinie benennt Auen zwar nicht direkt als Handlungsobjekte. Betrachtet man jedoch ihre verschiedenen Vorgaben im Zusammenhang, wird deutlich, dass Auen als Funktionsräume mit erfasst sind, weshalb zukünftig aus wasserwirtschaftlicher Sicht auch konkrete Anforderungen an ihren Schutz und ihre Entwicklung zu stellen sein werden. Zudem können Maßnahmen am Fließgewässer, die zum Erreichen der Umweltziele der WRRL erforderlich sind, zu Veränderungen der Bedingungen in Flussauen führen. Dies wird an Beispielen aus der Unteren Havel näher erläutert. Damit ergeben sich Überschneidungen mit den Zielen und Aufgaben des Naturschutzes in Flussauen, die eine enge Abstimmung von Wasserwirtschaft und Naturschutz erforderlich machen. Besonders bei der Festlegung von Entwicklungszielen sind Gemeinsamkeiten und mögliche Konfliktpotenziale frühzeitig zu identifizieren. Dazu ist es erforderlich, dass von der Wasserwirtschaft der Einfluss der Auen auf den Zustand der Wasserkörper bereits bei der Beschreibung der Referenzzustände, der Bewertung der Risiken für das Erreichen der Umweltziele sowie der Entwicklung von Maßnahmenprogrammen berücksichtigt wird. Um Einfluss auf die Maßnahmenprogramme n. WRRL nehmen zu können, wird es Aufgabe des Naturschutzes sein, auch über das Schutzgebietssystem NATURA2000 hinaus eigene gewässerbezogene Zielsysteme zum Auenschutz aufzustellen.
Monitoring of groundwater and surface water levels in the Middle Havel area - a basis for the management of landscape water resources The lowland of the middle stretch of the River Havel ("Mittlere Havel", Brandenburg, Germany) is characterised by hydrological conditions that are deeply influenced by draining for agricultural land use. In this area strategies for the sustainable management of landscape water resources are tested in a development and testing project, funded by the German Federal Agency for Nature Conservation. For monitoring of environmental change, the scientifical accompaniment of the project established a network of gauges, measuring ground water levels, water levels in ditches and in the River Havel itself. Data is gathered in areas that are potentially endangered by flood and areas that are protected by embankments. Until now, data from this network is available for more than two hydrological years since autumn 2001. It shows that water level dynamics are mainly influenced by precipitation and evaporation. Only in areas, which are under the potential influence of floods, ground water levels reach water levels in the river during winter term. In areas that are protected by embankments and additionally drained, surface and ground water levels are actually lower than water levels in the river. In addition, ground water levels are influenced by lowering the water levels in ditches. A sustainable landscape water management therefore has to be realised primarily through an altered management of water scoops in the diked areas. This requires the detailed analysis of all relevant hydrological and meteorological data including data about the water scoops.
