Assessments of Biodiversity and Habitat Services in Cities – Exemplified by Dresden (Germany) and Liberec (Czech Republic)

Abstract The choice of suitable biodiversity assessment methods for practical purposes in city planning and decision-making is still a challenging problem. Despite the availability of a wide variety of methods for almost all dimensions of diversity (mainly species and habitat diversity, including spatial aspects), few of them have entered the practical ‘daily’ work. In the example of in-depth examinations in German and Czech cities (e.g., Dresden and Liberec), it was found that the most frequently applied analyses are those of protected species and habitats in urban nature conservation in general, and particularly in city development planning to derive avoidance, protection and compensation measures. Preference analyses (questionnaires, structured interviews) are becoming increasingly popular. Economic calculations of habitat values and the valuation of ecosystem services are still in their infancy. We will present methods that are presently being applied or could be included in a practical methodological toolkit to analyse and valuate biodiversity in urban nature conservation, city planning and decision-making.
