Recent studies showed that green spaces in cities (e.g. parks, allotments, cemeteries) provide habitat to numerous species and may fulfill basic nature conservation functions. In this project we investigated main factors driving the species richness within urban green spaces in Hannover, Germany. We especially focused on the effects of patch size and distance to the urban edge, but also investigated effects of other patch metrics, habitat heterogeneity and connectivity of urban green spaces. The relevance of these measurements was investigated for vascular plants, mammals, and birds.
Our results showed that patch size as well as the number and diversity of habitats within urban green spaces were of overriding importance for total, native, and endangered plant species richness, as well as total and native bird species richness. An analysis across all the investigated taxonomic groups underlined the importance of patch size and habitat heterogeneity. We conclude that, in the context of urban ecological planning, it is important to conserve large green spaces that include a high diversity of habitats to maintain high species richness.
The joint Lower Saxony - Israel research project was carried out by the Institute of Environmental Planning, Leibniz University Hannover and the Faculty of Architecture and Town Planning, Technion – Israel Institute of Technology. In addition, the Department of Geography and Environmental Studies and The Golan Research Institute, University of Haifa, participated in the study. This joint research project was financially supported by the state of Lower Saxony, Hannover, Germany (VWZN2631).
