As part of the “Multispecies Campus” Living Lab at Freie Universität Berlin in Berlin-Dahlem, Studio Animal-Aided Design developed a solid foundation for the future maintenance and design of open spaces and buildings with a focus on biodiversity promotion. The aim was to use the method of Animal-Aided Design (AAD) to integrate suitable animal species at an early stage in upcoming spatial transformations and to enable measures to support urban nature. A central element of the project was a participatory target species selection workshop involving students, faculty members, and staff of Freie Universität Berlin. In topic-specific groups, species proposals were discussed and evaluated based on criteria such as visibility, conservation value, feasibility, and conflict potential. Specially developed target species cards were used, enabling an accessible and engaging exploration of the animal world. This process led to the consensus-based selection of target species — ranging from the Slender Ground-Hopper (Tetrix subulata) to the European Green Woodpecker (Picus viridis) — which will serve as a basis for specific animal-friendly maintenance and design measures. The project thus not only lays the groundwork for a biodiversity-oriented transformation of the campus, but also fosters a vibrant, identity-forming engagement with urban nature — linked to climate adaptation and the improvement of the campus’s quality of stay.
