Hankensbüttel Otter Centre

The Hankensbüttel Otter Centre is a significant nature experience centre located in Hankensbüttel, within the German district of Gifhorn. Spanning 6 hectares (15 acres) of open land adjacent to the Isenhagener See, the centre is dedicated to showcasing the European otter, a species facing threats of extinction, alongside several related species from the marten family. It operates as a popular tourist and visitor destination, offering an immersive natural environment for its inhabitants.

History and Organization

The origins of the Otter Centre can be traced back to the Fischotter-Forschungsgehege Oderhaus (Oderhaus Otter Research Station), established in 1979 near Sankt Andreasberg in the Harz mountains by the Lower Saxon Forestry Commission. Claus Reuther was instrumental in its founding and also established the Aktion Fischotterschutz (Otter Conservation Project) in Braunlage in 1979. Following the conclusion of the research project in 1986, the group conceived the idea for a dedicated otter centre, which subsequently opened in Hankensbüttel in 1988. This transition marked its evolution from an otter conservation group into a state-recognized nature conservation organization. Claus Reuther served as the head of the centre from its inception until his death in 2004. The facility experienced a setback in 1993 due to a serious fire in its main building, though Reuther was later acquitted of arson charges.

The Aktion Fischotterschutz and the Hankensbüttel Otter Centre have received numerous national and international accolades for their conservation efforts, including awards from the World Wildlife Fund, the Emmy and Karl Kaus Prize for Animal Conservation, and recognition as an official project in the UNESCO "Creation of Sustainable Development" world decade.

Animals and Habitat

The otters at the centre are housed in spacious enclosures designed to replicate their natural habitat, complete with streams and ponds. In addition to otters, the centre displays various species of marten, which are closely related to otters. This presentation of multiple related species in a single facility is considered unique. The species exhibited include the badger, stoat, polecat, beech marten, pine marten (with the centre boasting the only pine marten enclosure in Europe), mouseweasel, and European mink. The enclosures and habitats are meticulously designed to reflect the animals' native environments, featuring elements such as streams, ponds, lakes, swamps, hedgerow landscapes, and woodlands. Notable enclosures include the badger hill with a visitor tunnel, otter ponds and brooks with underwater viewing points, and specific houses and barns for marten species.

Visitor Experience and Education

Attracting around 100,000 visitors annually, the Otter Centre provides a rich environmental education program. This is achieved through practical learning and experimentation, with mechanical aids and interactive exhibits designed to illustrate various ecological concepts. Visitors can test their knowledge through question boards and engage in educational games. The centre also hosts approximately 60 special events each year, particularly for children, focusing on historical and nature-themed activities. Visitor facilities include a visitors' hall, an otter shop, and a restaurant.

Research and Conservation Initiatives

Beyond public dissemination of information, the Hankensbüttel Otter Centre is actively involved in research, primarily conducted in areas separate from public access. These research enclosures are equipped with ponds and are focused on understanding the specific needs of otters and other species. Young animals born in captivity are typically conceived and born within these research grounds to ensure a peaceful birthing environment for pregnant females.

The centre also engages in biotope conservation by acquiring or leasing land with running water in various locations across Lower Saxony. These efforts aim to develop secluded habitats for otters, exemplified by the revitalization of a canalised water system on the Ise to resemble its natural state. A key principle of this biotope conservation approach is to foster cooperation and understanding with local residents, encouraging agricultural practices that are compatible with nature while maintaining protected strips along riverbanks.
