In response to biotic and abiotic changes in the urban environment, animal and plant populations and communities rearrange, accommodate and/or adapt. Understanding the processes leading to these different responses is essential to designing more ecological and resilient cities. We have launched an observatory on the taxonomic and functional diversity of urban plant communities and populations under various artificialization and management contexts. The pooling of various skills in ecology, geomatics and human sciences allows us to improve our understanding of the mechanisms at work in the adaptation of biodiversity to humans, their constructions and activities. Our project aims to study the taxonomic and functional compositions of plant communities in 60 urban herbaceous areas of the Strasbourg Eurometropolis. We intend (1) to measure the variability of these compositions in response to different urban forms, human densities and applied management and (2) to specify the adaptation mechanisms involved in this response. This study will allow us to inform planners and managers about the functional state of urban nature spaces, to inform them about the beneficial, neutral or harmful influences of their actions on the capacities of species to grow, maintain and reproduce.
