NATURA 2000, an endeavour in the spirit of the Convention of Biological Diversity (Rio, 1992), is one of the success stories among pan-European initiatives and one of the worlds most effective legal instruments concerning biodiversity and nature conservation. The EU Habitats Directive (council directive 92/43/ECC) requires a standardised monitoring of the habitat types and a reporting every six years. For this reason, an operational, objective, economically priced and as far as possible automated application is required. The rapidly developing remote sensing sensor technique and also new image processing methods offer new possibilities to apply remote sensing data for NATURA 2000 monitoring. Today, with (i) GMES as an umbrella for utilizing latest EO-based achievements form both space- and in-situ sensors to provide European solutions for global problems of the environment-security-nexus, (ii) INSPIRE as a pan-European endeavor of obeying standards and other prerequisites of interoperable use, and (iii) the vision of a unified and integrated (i.e. single) European Information Space (SEIS), set the stage for a technologically mature, integrated, and user-centric system, more effectively to be used than ever. Users are in need, as imposed by the legally binding character of the directives, and this is what this project will service, from European to local scale. MS.MONINA follows a pan-European, multi-scale approach that on the one hand reflects the specifics and the variety of habitats in the different biogeographical regions, and on the other hand guides the specifications of the service chains and their implementations as service cases and pilots. The multi-scale (MS) concept reflects the fact that on different (administrative) levels there are specific requirements for sensitive sites-related reporting, monitoring, management etc.

To study the time trend of PCDD, PCDF and dl-PCB levels in the muscle of herring from the Western Baltic Sea, samples were collected in 2006 at the same fishing locations as in 1999. The results demonstrated no obvious change in contamination levels based on content in fat during the last 7 years. The site-dependent increase in WHO-PCDD/F-PCB-TEQ concentrations already found in 1999 in fishing grounds between the Skagerrak and the east of Bornholm could be confirmed by this study. In addition, an overview is given in this study on the actual WHO-TEQ concentrations in cod, eel, herring, sprat and some salmon landed at various fishing ports along the coast of Mecklenburg-Western Pomerania/Germany. All herring samples were found to be below the maximum levels and the concentrations in cod were below 1 ng WHO-TEQ kg -1 wet weight (ww). The contaminant levels of 28 pooled eel samples varied considerably between 1.35 and 16.75 ng WHO-TEQ kg -1 ww. The results are discussed in relation to the fat content and to the weight of the eels. © 2009 Elsevier Ltd. All rights reserved.

Black Soils with dark-coloured, mollic horizons occur in the Baltic region of Germany and their classification as Chernozems was previously discussed. Mollic topsoil horizons are diagnostic for steppe soils. We therefore hypothesized that the molecular characterization of soil organic matter (SOM) by pyrolysis-field ionization-mass spectrometry (Py-FIMS) is suitable to identify similarities between the Black Soils and Chernozems as well as soils from other major soil groups with mollic horizons or otherwise high SOM content. Data were collected from a set of 341 topsoil samples and analysed based on 139 Py-FI mass spectra and thermograms. The OC content in Black Soils reached high values matching those of Haplic Chernozems from Germany and typical steppe climate ecosystems. Arable soil use converted Ah horizons to lighter-coloured Ap horizons that nonetheless had a similar or higher OC content than underlying Ah horizons. Arable soil use led to less stable SOM as indicated by a higher percentage of volatilized organic matter (VM) upon pyrolysis. Furthermore, VM was especially high (21-52%) for redoximorphic soils, whereas it ranged between 5.1 and 15% in the Black Soils, Chernozems and other steppe soils such as Phaeozems or Kastanozems. Assignment of marker signals from Py-FI mass spectra to the compound classes revealed that Black Soils, all Chernozems and other steppe soils had more phenols and N-containing compounds but less sterols and suberin than most of the other soil groups investigated. The percentage of volatilized organic matter (VM) - with low values hinting at SOM stabilization in soil - ranged from 5 to 52%. It was especially high for redoximorphic (21%) and organic soils (52%), whereas it ranged between 5.1 and 15% in the Black Soils, Chernozems and other steppe soils. Principal component analysis unravelled the SOM composition patterns of different soils and showed that the Black Soils clustered together with typical Chernozems, while soils of other units differed. This indicates that sources and especially humification pathways of SOM were different in these soils compared to Black Soils and Chernozems. Notably, this was the case for Colluvic soils (= Colluvic Regosols), redoximorphic soils (e.g. Gleysols, Stagnosols), Luvisols and Phaeozems, although colluviation, influence of ground- or stagnant water, and clay migration were found in several Black Soils as well. Our findings do not support a strong, direct influence of colluviation and perched water on the SOM composition in the mollic horizons of Black Soils. The data also show that the Chernozem-specific SOM formation and clay migration, as in Luvisols and Phaeozems, are temporally discrete processes. The results underline that Chernozem formation in Central Europe is a relic process and is not only due to steppe ecosystem conditions. Rather, it depends on parent substrate properties, especially clay and carbonate content, secondary carbonate input and anthropogenic soil use. These factors preserved or even regraded the relic Chernozems since the Atlantic stage. © 2013.

In Schleswig-Holstein, Germany, various flow-deflectors are used as instream measures for the restoration of streams and rivers since several years. The effect of such measures on the hydromorphology and the status offish was analysed. In seven restored and control reaches, the variability of depth and the residual pool depth were measured, streambed structures were mapped and the status of substrate composition and offish was evaluated. Additionally, the individual flow deflectors made from wood and gravel depositions were categorized and compared with wood structures in near-natural streams. Based on these comparison recommendations for a more natural design of instream measures were developed. The instream measures, have been mainly installed in 2008, improved the diversity of streambed structures and hence, variability of depth in the reaches. Only a few changes were found regarding the residual pool depth, channel development and status of stream substrate and fish. The form of instream measures clearly differed from natural depositions of coarse woody structures. To increase hydromorphological and ecological effectiveness it is recommended to increase variability of instream measures, especially in size, and to orientate their design on natural wood structures.

The perennial red macroalga Gracilaria vermiculophylla (Ohmi) Papenfuss has recently been introduced to the Baltic Sea and is a potential competitor to Fucus vesiculosus, the most common native perennial alga in large parts of the Baltic Sea. Gracilaria might interfere with Fucus through direct competition for resources. In addition, Gracilaria is a favoured refuge for mesograzers, which prefer to feed on Fucus. Mesocosm-experiments were conducted over one year in the Kiel Fjord in order to test the direct and indirect effects of Gracilaria on Fucus. Fucus was incubated with Gracilaria at three different densities and grazers in high or low abundances. High densities of Gracilaria inhibited the growth of Fucus adults and also reduced the half-life-time of Fucus germlings. Associated grazers also had a negative effect on Fucus adults. Our results suggest that Gracilaria is able to influence Fucus in the Baltic Sea through direct competition for resources and by exposing it to higher grazer pressure. © 2013 The Author(s).

Agricultural raised bog habitats have been changed during last decades. Drainage, fertilization and intensive use as grassland and acre have caused mineralization and reduction of peat. A profitable utilisation is hardly yet possible; reasons of climate protection are opposing to deep cultivation with following agriculture. Giving up agricultural use in connection with increase water-level would make sense for achievement specific aims of nature protection, whereby coincidentally the emission of CO2 cold become impaired. Also energy recovery of herbages has become proved. Several research programms, field reports and ideas for a future use of raised bog habitats have been presented and discussed in this seminar.

Within the framework of projects of renaturation in many raised bogs in Schleswig-Holstein birches have been cut and pulled out, but with varying success. Several studies and observations of many years result in a different management of birches in bogs due to the requirements.

The program for protection of peatland in Schleswig-Holstein with an area of 192.000 ha includes all peatsoils of raised bogs and fens and all biotopes and grassland on peat. Aiming to develop biodiversity as well as to contribute to climate protection many projects are financed with funds of the state but above all with subsidies of EU. The selection criteria for development area and the practical experience with performance of restoration projects are described.

WFD identifies a pressure as significant, when the pressure contributes to an impact that may result in the failing of "good status" for the specific waterbody and as a consequence demands the implementation of appropriate measures. An indication for a significant sewage treatment plant discharge is the status of the biological (and chemical) quality elements of a waterbody. Working thesis for a statewide project to estimate potential significance of sewage treatment plant discharges reads as follows: "If measured saprobic index does not meet good status, the sewage treatment plants in the belonging catchment area are interpreted as significant when the measured value for NH4-N at the saprobic monitoring station (after mixture at average low water discharge) exceeds the LAWA-benchmark." In the LLUR-project a first statewide estimation included 950 municipal and industrial waste water treatment facilities under consideration of more than 700 saprobic monitoring stations.

In the year 2000, the benthic and hyporheic ostracod species were investigated in the groynes and the groyne fields of the river Elbe. In total only 12 species were found. The low number of species is owing to the few mesohabitats that occurred in the channel that was altered for navigation purposes, and that the river was severely polluted in the past, which led to an extinction of most species. Since about 1992 the Elbe is in a continuing phase of recolonization. Remarkably, the juveniles of the two species Pseudocandona albicans and Limnocythere inopinata occurred predominantly in the hyporheal within gravel of subaqueous dunes. © 2013 WILEY-VCH Verlag GmbH & Co.
