In 1993, the working group 'Methods of biotope mapping in populated areas', which was set up by the Federal Nature Conservancy Office in Bonn, updated its 'Basic program' for gathering, organizing and analyzing data relating to urban biotopes (Schulte et al. 1993). The 'Biotope mapping of Mainz', a research project carried out by an interdisciplinary group of geographers, biologists and environmental planners at the University of Mainz between 1993 and 1996, both attempted to transfer the objectives and recommendations of the 'Basic program' to the local situation and to remove shortcomings within its methodological framework. In conformity with the legal mandate, the work is based on the strategy of integrated nature conservation, i.e. simultaneous protection of biotic, abiotic and aesthetic resources, which is considered as an inevitable component of sustainable development in urban areas. Among the new methodological aspects recommended in the 'Basic program' and completed in the 'Biotope mapping of Mainz' are improvements upon the biotope-type reference key, very detailed descriptions of biotope-types, subtypes and variations, the elaboration of a small-scale biotope-type key withrelevance to flora, fauna and aesthetics, mappings and descriptions of the natural phenomena, recreational activities and environmental impacts related to biotope-types. Further, the 'Biotope mapping of Mainz' supplemented some new spatial aspects and assessment proceduresn that might eventually get planning authorities more adapted to the idea of sustainable development in populated areas, such as the zoning of urban nature, the delimitation and description of 'urban landscape units' (including climate, soil and water conditions, flora and fauna as well as historical and cultural features), the development of environmental quality aims and standards specified for each 'urban landscape unit', the assessment of the unit's biotope-types with reference to the established environmental quality standards, and last, suggestions and recommendations for urban planning and environmental management. A synoptic table will resume the project's issues with relation to the 'Basic program'.
