The realization of the redevelopment concept Großes Meer is able to illustrate, how the instruments of land development (land consolidation and village renewal measures) may assist the process of coordination of the numerous actors of a complex project. Furthermore, the integrative approach of land consolidation not only allows the adequate allocation of the lots due to the requirements of planning authorities and within the allocation of equal values, but in many cases may also implement the planning basics for construction work and support it according to the Directive on Granting Integrative Rural Development.

Lapwing and Wind Turbines-results of a seven year study in the south of East Frisia In spite of a multitude of studies concerning the influence of wind turbines on birds (many of them on the lapwing) there are still uncertainties about the assessment of the effects of wind turbines on this species. A seven year BACI-study (beforeafter-control-impact) investigated the influence of wind turbines on breeding lapwings. The parameters analysed comprised population trends, spatial distribution and the distance to the next turbine, breeding success as well as the influence of certain habitat parameters like type of agricultural use and the distance to woods and hedges. With the data from two years multiple logistic regression models were calculated to compare the density of lapwings in areas of same habitat quality. Parameters like agricultural land use, distance from hedges and vegetation structure had more influence on the dispersal of lapwings than the distance to the next turbine. Lapwings also bred within the wind farms but showed displacement effects up to 100 m.

Exploration and production of oil or gas in protected nature areas require a comprehensive and flexible approach in order to adapt the project to the specificity of the respective conservation objectives. Approvability can only be achieved if all reasonable technical and logistic alternatives, which are able to minimize the environmental impact, are exhausted. These principles are illustrated by experiences from 10 years of handling different projects within Germany's largest oil field located within a Wadden sea national park: the laying of two pipelines and two sea power cables, the establishment of extensive scour protection and the preparatory planning for four exploration wells. All projects had to be assessed against the conservation objectives of different regimes: national park, biosphere reserve, nationally protected habitat, European Habitat Directive, European Bird Directive, special species protection and - since 2009 - UNESCO world heritage site. The examples illustrate in which way the technical and logistic concepts were - sometimes radically - changed and adapted to the conservation needs of the area. The main topics to be addressed were: Strict avoidance of any contamination of the environment (zero discharge principle) Avoidance of sensitive periods, Avoidance of raising soil temperature more than two Kelvin, Minimization of area use Extensive monitoring Implementation of compensation measures (revitalization of salt marshes) These examples of good practice show how an environmental optimization of projects can lead to successful application procedures (even confirmed in court cases). Thus it can enable the exploration and production of oil or gas in protected and environmentally highly sensitive areas. In this way environmental impact assessments should not be seen as static evaluations but rather as a process during which a project is adapted and optimized towards approvability.

Since October 1987, RWE Dea (operator) and Wintershall Holding GmbH (partner) have developed the most significant German oil reservoir in the field Mittelplate. The production of more than 25 million t of crude oil to date has chiefly been carried out via the artificial island Mittelplate located 7 km off the coast near the southern border of the national park known as "Schleswig-Holsteinisches Wattenmeer", which also has the status of a world natural heritage site since 2009. The lighting facilities on the Mittelplate drilling and production island were optimised against the backdrop of this sensitive environment. Birds migrating by night are attracted by large-scale artificial light sources, especially when visibility is poor. This leads to impairments for bird life in the form of disorientation, dissipation of energy, collisions and increased decimation by predators. This phenomenon is particularly problematic in offshore regions. As regards the impact of green, blue and red spectral ranges of light, there are contradictory statements in specialist literature. While van de Laar [I] and Poot et al. [2]describe that nocturnally migrating birds are attracted by red light rather than by blue and green light, Evans et al. [3]discovered exactly the opposite. Against this backdrop, RWE Dea AG has abstained from using e. g. green light for the time being, opting for a reduction of the light being emitted into the environment instead. To this end, various measures have been implemented on Mittelplate island to date. All lighting facilities potentially emitting light externally on Mittelplate island were recorded, classified and examined with regard to their optimisation potential. A description of the de-commissioning, switching and optimum alignment of light sources, the installation of light guidance shields as well as control of light sources via the process steering system is given. Moreover, compliance with safety at work rules and regulations is dealt with. In order to document the success of the relevant measures, photographs were taken in darkness subject to identical conditions before and after implementation of the optimisation measures. In strict compliance with safety at work rules and regulations, by implementing these measures it was possible to bring about a mitigation of the impacts of Mittelplate particularly on nocturnally migrating birds. © 2011 URBAN-VERLAG Hamburg/Wien GmbH.

Application of Legal Species Protection in Planning Procedures - Limits and options After the Small Amendment of the Federal Act on Nature Conservation in 2007, supported by several decisions of national courts, species protection is meanwhile playing a central role in planning procedures. This calls upon practical planning to find solutions which are both legally safe but also practicable in order to guarantee the compatibility of planning and species protection. The paper outlines the legal requirements for species protection assessments and provides solutions for different problems of species protection using select examples. Using current planning projects the different types of prohibitions are explained using examples of European bird species and bats, the fish species houting (Coregonus oxyrinchus) and the plant species Elbe Water dropwort (Oenanthe conioides). These investigations show that the existing legislation and supportive interpretations are not able yet to answer all questions of species protection. This makes clear that determinations of nature conservation values hit the walls due to knowledge gaps regarding the relationship of ecology and population biology.

In April 2013 the second draft for a Ordinance on the Compensation for Interventions in Nature has been presented in order to implement a federal standardisation of the impact regulation. The draft has already passed the Federal Cabinet but still needs acceptance of the Federal Assembly. The paper outlines the major content of the draft ordinance and its comprehensive appendices, and it evaluates the basic compensation model from a viewpoint of practical planning. Beside positive aspects of the new regulations it identifies deficits of the draft, and it suggests additional concretions and desirable adaptations which could improve its practicability.

The assessment pursuant to the Habitats Directive of large instrastructure projects and other construction schemes has meanwhile become day-to-day business in practical planning. The procedure of derogation, however, which is necessary if the impact might not be compatible with the conservation aims of the protection areas has so far more or less been unknown territory. The legal conditions have meanwhile been defined by the Habitats Directive, the Federal Nature Conservation Art and different definitions of the Federal Administrative Court. This is particularly true for the aspects "examination of alternative solutions" and "overriding public interest". There is, however, still a certain insecurity regarding the delineation of the measures to ensure coherence against the so-called "anywaymeasures". At the moment there is still need for close agreement with the local nature conservation authorities. Yet wider perspective allows the conclusion that the derogation procedure according to the Habitats Directive is not an incalculable and unforeseeable approval procedure. The efforts might be higher compared to a "simple" impact assessment according to the Habitats Directive but in difficult cases the derogation procedure increases the legal security for the project proponent.
