By presenting the process of developing an augmented reality (AR) installation, the paper explores the transformative potential of AR as a mediation tool in the context of a multifaceted socio-cultural issue. Focused on the removal of a 120-year-old Atlas cedar from a municipal park in the German town of Ratingen, the study employs research through design (RtD) approach, combining qualitative field research and digital documentation. The AR application serves as a platform for location-based storytelling, aiming to foster dialogue among citizens, scientists and city officials through a multi-perspective approach. As the project envisions a future where AR serves as a potent tool for mediating intricate societal challenges, this paper adds to the ongoing discourse regarding the convergence of technology, nature, and public engagement.
