    Description: Alpha ventus was the first German offshore wind farm build in the German exclusive economic zone in 2008/2009. The data are part of the mandatory monitoring programme of the German Standard Investigation of the Impacts of Offshore Wind Turbines on the Marine Environment (latest version: StUK 4, published by BSH 2014). Makrozoobenthos was collected in the offshore wind farm alpha ventus at four wind turbines at different depth (epifouling communities), distance-dependent to the turbines in the soft bottom, as well as randomly within the soft bottom of the offshore wind farm area and in a comparable reference area nearby. Samples were taken by scrape samples with scuba divers to analyse the epifaunal communities and with van-Veen grabs to analyse the infauna. Soft-bottom samples in the wind farm and reference area were collected in spring and autumn from 2008-2012 before, during and after construction (until three years) of the wind farm. After construction of the turbines, epifaunal community was evaluated for recording successional stages of growth on the wind turbines in different depth to cover the vertical zonation along the turbines (at 1, 5 and 10 m depth). Further, soft-bottom samples were collected distance dependent to the turbines 100, 200 and 400 m apart from the turbines. Biodiversity data of species include abundance (count data) and biomass (wet mass, g) per sample. Data were sampled on behalf of the DOTI GmbH & Co. KG in the framework of the mandatory monitoring and collected and quality controlled by the Federal Martime and Hydrographic Agency (BSH) in cooperation with AWI. Thus, we would like to thank the DOTI GmbH, particularly Magdalena Buchholz on behalf of the DOTI GmbH, as well as the BSH, in particular Dr. Maria Boethling, who kindly provided the data for scientific independent research analysis and publication.

    Description: 1. According to the EU Marine Strategy Framework Directive (2008/56/EC), marine protected areas (MPA) should contribute to a good environmental status of the Europeans seas. Measures maintaining or restoring a favourable conservation status of protected species and habitats are mandatory according to the EU Habitats Directive (92/43/EEC). 2. Identification of suitable sites for ecological restoration measures within MPAs is a crucial step towards successful conservation and sustainable MPA management. In terms of species restoration, it is important to restore the respective species with the best possible environment for growth, survival, fitness, and successful recruitment. 3. This study provides a comprehensive list of site-selection criteria for ecological species restoration. Three general categories were chosen: (1) ecological history: evidence for the historical distribution; (2) feasibility of restoration: regulating framework and logistics; and (3) environmental conditions: quality of abiotic and biotic factors. A total of 16 site-selection criteria were identified and applied to biogenic reef restoration, namely for reefs of the native European oyster Ostrea edulis, in the German Bight. 4. The Natura 2000 area Borkum Reef Ground was identified as a suitable site for oyster restoration. It is one of three MPAs in the German Exclusive Economic Zone of the North Sea, which have been declared as Nature Conservation Areas according to national legislation. The conservation objectives include maintenance or, if necessary, restoration of the habitat type ‘reefs’. As a reef-building species, the European oyster O. edulis is of particular importance for this habitat type in terms of nature conservation.

    Description: Marine sublittoral sandbanks are essential offshore feeding grounds for larger crustaceans, fish and seabirds. In the southern North Sea, sandbanks are characterized by considerable natural sediment dynamics and are subject to chronic bottom trawling. However, except for the Dogger Bank, sandbanks in the southeastern North Sea have been only poorly investigated until now. We used an extensive, multi-annual dataset covering ongoing national monitoring programmes, environmental impact assessments, and basic research studies to analyse benthic communities on sublittoral sandbanks, evaluating their ecological value against the backdrop of similar seafloor habitats in this region. The analysis revealed complex spatial structuring of sandy seafloor habitats of the southeastern North Sea. Different infauna clusters were identified and could be specified by their composition of characteristic species. The sandbanks shared common structural features in their infauna community composition although they were not necessarily characterized by particularly high biodiversity compared to other sandy habitats. A close association of one of the main bioturbators in the southern North Sea, the sea urchin Echinocardium cordatum, with sandbanks was detected, which may promote the sediment-bound biogeochemical activity in this particular seafloor habitat. This would corroborate the status of sandbanks as sites of high ecological value calling for consideration in marine conservation.
