In the past few years, the Geneva vineyard has significantly changed its soil management practice: permanent grass cover has become a common practice. This article provides a detailed analysis of the grass cover in the canton of Geneva and launches a discussion on opportunities for improvement. It demonstrates that the flora of the vineyard is diverse but dominated by a few species typical of fertilized meadows, occupying a large area. The frequency of mowing does not seem to influence the flora composition. With some small extra effort, the majority of vineyards could be considered as ecological compensation areas, a good advantage for vine growers qualifying for direct payments. For the weeded plots in this study, 50 % could be covered with permanent grass without too much risk. Therefore, there is still much to be done to promote permanent grass cover.
