The potential for promoting biodiversity in urban areas is great, and the willingness of actors to get involved is increasing. In order to be able to do this, planners, developers and municipalities need - in addition to knowledge and legal foundations - well-supported and practicable benchmarks for biodiversity that can be easily and efficiently integrated into spatial instruments and processes. Such benchmarks and quality criteria exist for different spatial levels and building contexts in Switzerland and other countries. They are to be compiled and evaluated in a report and recommendations regarding their integration into spatially relevant processes and instruments are to be derived.
