The process of urbanisation leads to a series of transformations and disturbances that may have consequences for wild plant communities. This thesis presents a study of the plant communities of ordinary grasslands distributed among three cities of western France: Angers, Nantes and La Roche-sur-Yon. Using both taxonomical and functional approaches, the aim is to analyse the variation in plant diversity and composition along landscape gradients, in particular those of urbanisation and habitat connectivity. Such grassland habitats appear to be diverse, despite a low number of exotic species. The urban-rural gradient structures such communities, in particular by strongly modifying species composition; and this despite an absence of variation i...
