How a Cold War border became Europe's thriving green wildlife haven
An evening lecture on the Green Belt Thuringia National Natural Monument will take place on March 6, 2026. The event, organised by the Geisa Art, Culture, and Science Association, will explore how a former border zone has also become a haven for rare wildlife and delicate ecosystems. Speaker Ralf Hofmann, regional manager for the Rhön section, will share insights into conservation efforts along this unique landscape.
The lecture will also highlight the balance between protecting nature, preserving history, and supporting sustainable outdoor activities. Alongside the talk, a photography exhibition titled Around the Green Belt will showcase the area's natural beauty.
The Green Belt Thuringia National Natural Monument stretches along the route of the former Inner German Border. Once a divided and heavily guarded area, it now thrives as a 12,500-kilometre network of habitats connecting 24 European countries. The Thuringian Nature Conservation Foundation has managed its protection and development since its designation as a Nationales Naturmonument in 2023.
The region supports an extraordinary variety of life. Over 1,200 species listed on the Red List of threatened wildlife find refuge here, including the black Apollo butterfly, the large blue butterfly, the meadow pipit, and the red kite. Rare habitats such as limestone grasslands and mountain hay meadows also flourish along the belt.
Since 2018, the foundation has worked on restoring 146 biotope types. Projects include reviving traditional meadow irrigation, converting forests to near-natural states, and creating dead wood habitats. Funding from the EU LIFE program has supported biotope mapping, invasive species control, and public awareness campaigns. Volunteers and partnerships with the Thuringian state government have played a key role in these efforts.
During the lecture, Hofmann will explain how conservation, historical remembrance, and nature-friendly recreation can work together. The event aims to raise awareness of the Green Belt's ecological importance while celebrating its transformation from a symbol of division to one of unity and biodiversity.
The lecture and exhibition will provide a closer look at one of Europe's most significant conservation projects. Attendees will learn about ongoing efforts to protect endangered species and habitats along the former border. The event also offers a chance to see how community involvement and scientific work are shaping the future of the Green Belt Thuringia.
