What does an ecosystem actually sound like? What hidden worlds of life become audible in the Botanic Garden - and how are we connected to them? We invite you to join us on exciting sound journeys on the grounds of Wir bauen Zukunft.

After intensive research, sound recordings of the biotopes and audio productions, we will experience the species-rich flora and fauna in acoustic stories. With the Biosphera audio tours, listen to the exchange of trees and fungi, the communication of bats, birds and insects - or immerse yourself in the wafting earth and underwater worlds. A new audio tour app has also been developed as part of the project and can be tested on site.
