- Abstract
The aim of this article is to identify both the diversity of plant associations in the extensive grasslands of the Geneva city parks as well as the different factors potentially influencing their composition and to propose suitable management measures. Methods: The vegetation was characterised according to the sigmatist phytosociological method. The data were then entered and standardised with the VEGEDAZ software, then attached to a reference unit according to the identification key of the Geneva syntaxonomic reference system. The settlement types and practices were identified and coded, then analysed with the R studio software. Results and discussion: Forty-three readings were carried out and sixteen associations identified. The most common association is Salvio-Mesobrometum. This demonstrates the resilience of urban parks to recover a diverse oligotrophic flora despite past intensive management. At the same time, the extensive grasslands of the Arrhenatherion (Lolio-Arrhenatheretum, Ranunculo-Arrhenatheretum and Tanaceto-Arrhenatheretum) are mostly the result of transformation linked to practices, for which the use of scythes and the removal of hay, seems to favour the number of species present. Finally, the ruderal environments constitute refuges for several heritage species.
