Nowadays, more than half of the World’s population is urban (in Switzerland app. 75%), with an increasing trend. Even though the novel urban ecosystem is often undervalued, it supports surprisingly high biodiversity and is essential for human well-being. Our project ‘BiodiverCity’ adopted a novel trans- and interdisciplinary research approach, with ecologists, social scientists, practitioners, and stakeholders working together, to assess urban biodiversity and attitudes of people in order to identify the needs of the residents and key factors that positively influence quality of life and biodiversity in the urban environment.
Invertebrates, birds, and bats were investigated in Zürich, Luzern, and Lugano, which were selected as being representative for small to medium sized European cities. Urban environmental variables measured at different spatial scales and space-only variables were used to identify urban matrix characteristics that most influence the number of species and community composition. The same urban characteristics were used in the interviews with the public at the national level and with urban residents. In this way, comprehensive conclusion are drawn, on how urban areas are to be planned and managed to support both, a diverse biodiversity and satisfied inhabitants.
