Project Details:
The decline in insect biodiversity with negative consequences for food webs and the loss of ecosystem services is currently dramatic. The causes of the decline in insect diversity are manifold, the qualitative deterioration of their habitats, whether on land or in water, light pollution, habitat loss, competition from invasive species and environmental toxins are just some of the factors. As part of this pilot project, flowering areas and nesting aids for insects are being created on the grounds of the University of Veterinary Medicine Hannover Foundation. The results of a species inventory serve as the basis for targeted measures to improve the habitat. The optimizations, e.g. the creation of flowering areas with regional wildflowers, deadwood areas and insect nesting aids, are only the first steps.
Through these measures to promote key species groups, such as wild bees and butterflies, other groups of organisms can also be promoted through deadweight effects due to the improved structural offer, in order to achieve a sustainable optimization of the entire TiHo site.
Further steps are planned as part of the project, which will be scientifically supported by Bachelor's and Master's theses. The TiHo grounds, which are near-natural in many areas, already provide important habitats for numerous rare animals and plants in the urban environment. These habitats are to be recorded in detail, protected and optimized. Other planned measures include improving the ecological condition of the Bünte pond in the park, creating an interactive insect trail and an exhibition with measures to promote biodiversity in urban areas.

Project Details:
Common Eider (Somateria mollissima) is classified as endangered in Europe due to continuous The population declines. Meanwhile, its occurrence along the coast of Schleswig-Holstein has potential for conflict with the culturally established and economically important fisheries.
This pilot study will develop approaches to startle common eiders from mussel farms and allow a sustainable coexistence of conventional fisheries in the Baltic habitat and protected species. The main focus is the protection of mussel farms against common eider predation. However, the results can potentially be transferred to fisheries, to prevent unintentional bycatch of birds in gillnets.
Post-mortem examinations of common eiders will be carried out simultaneously, to find out about potential pathological causes for the population decline and gain an insight into the health status of the population. These examinations include bacteriological, virological and parasitological analyses. Furthermore, toxicological analyses will deliver information about environmental pollution load.

The European Atlantic is changing rapidly, and it is essential that neighbouring countries have access to up-to-date robust information on the status of key species and populations so that future monitoring and management can be directed effectively and efficiently to achieve and maintain favourable conservation status of species and good environmental status of European Atlantic waters. The "Small Cetaceans in European Atlantic waters and the North Sea (SCANS)" survey is being planned for summer 2022. The objective of SCANS-IV is to estimate the abundance of cetacean species in shelf and oceanic waters of the European Atlantic through a large-scale multinational aerial and shipboard survey in July 2022. This is the most appropriate survey month because of the higher probability of good sighting conditions, and also to ensure that results are comparable with those from SCANS surveys conducted in 1994, 2005/2007 and 2016 (Hammond et al. 2002, 2013, 2021). Thus, this project will represent the fourth survey in the SCANS series. SCANS-IV will deliver regionally coordinated synoptic surveys in shelf and offshore waters of the European Atlantic. It will generate robust abundance estimates for regularly occurring whale and dolphin species and improve power to detect trends in shelf and offshore species. The outputs of the project are timely for EU Member States obligations for reporting under the Marine Strategy Framework Directive (MSFD Article 8: due 2024) and the next reporting round under the Habitats Directive (Article 17: 2019 - 2024) (where applicable) and allow OSPAR/HELCOM assessments. The estimates are also needed for impact assessments of offshore industries and fisheries.
The project will be achieved through the successful completion of six work packages. The first two WPs (WP1 & WP2) focus on collecting data on cetacean abundance and distribution through implementation of aerial surveys on the continental shelf and shipboard surveys in offshore waters. The data will be analysed in WP3 to generate abundance estimates, trends and perform spatio-temporal habitat modelling. WP4 will consider the long-term security of the large-scale cetacean monitoring SCANS programme in the Northeast Atlantic and propose a governance structure to ensure the continuation into the future. WPs 5 & 6 will focus on dissemination of results, project management and reporting.

Project Details:
The Eurasian otter (Lutra lutra) is (re-)expanding in all parts of the German federal state of Schleswig-Holstein (SH) nowadays. As an aquatic mammal, otters mainly inhabit rivers, streams and lakes but also forage along the coastlines. Otters primarily feed on fish, whereas they are considered food generalists and also target amphibians, crustaceans, birds, mammals and other invertebrates. It is assumed that the decline of certain endangeredeD fish species can be linked to the growing otter population. Furthermore, there is an increase in conflicts between fisheries and otter conservation, both nationally and internationally. Therefore, an extensive evaluation of the current conflict potential between the growing otter population, fisheries situation and conservation conflicts between species is needed. This will be covered in the frame of this research project that focuses on fisheries, natural otter habitat and spawning areas of endangered salmonids in comparison:
-Installing wildlife cameras to assess the local abundance of otters
-Dietary analysis to investigate the prey spectrum of otters
-Determination of otter individuals using spraints (genetic fingerprinting)
-Evaluation of a potential conservation conflict between otters and salmonids
-Development of acustic deterrents to protect fisheries from otters
-Analysing reproduction parameters to assess the population health of otters using specimens found dead

Project Details:
Two populations of harbour porpoise occur in the coastal waters of the German Baltic Sea, of which the "Western Belt Sea Population" is significantly larger with an estimated 42,324 individuals (acceptance range: 23,368-76,658), compared to the "Baltic Proper population", which is considered "critically endangered" with an estimated 497 individuals (acceptance range: 80-1,091). Harbour porpoise habitat in the Baltic Sea is intensely impacted by human activities that can have a negative impact on population level. These include shipping, tourist recreational activities, military activities, fishing, offshore construction, explosions of ammunition, chemical and pharmaceutical pollution, and marine debris. In the Baltic Sea in particular, harbour porpoise are threatened by set-net fisheries, to suffer from incidental bycatches. To warn harbour porpoises of set nets, acoustic devices are increasingly being used in the German Baltic Sea. These warning devices (Porpoise Alert = PAL) simulate a communication sound of harbour porpoises. Whether these devices lead to a reduction in bycatch has not yet been conclusively investigated. Effective management measures necessitate a deeper understanding of harbour porpoise habitat use. This is urgently needed, as there is evidence of declines in harbour porpoise populations in Schleswig-Holstein's waters.
The harbour porpoise is listed in Annex II and IV of the Flora-Fauna-Habitat Directives, which obliges EU member states to monitor its conservation status. In this project, the occurrence and habitat use of harbour porpoises in the western part of the Baltic Sea is investigated by means of passive acoustic monitoring. For this purpose, porpoise click detectors (CPODs, Cetacean-Porpoise Detector) were deployed at four positions in March 2021 to record the presence of harbour porpoises. The operated monitoring stations (Holnis, Bredgrund, Schleisand and Damp) cover the area of the Schleswig-Holstein Baltic Sea and are intended to close the gap in the monitoring network between Fehmarn and Denmark.
