Roth et al. present results of an analysis of change in vascular plant community structure at 129 sites in Switzerland over a 15-year period (2003-17) during which atmospheric nitrogen deposition had declined by about 15%. Their results show only weak shifts in plant community structure and little change in species richness. However, marked species turnover was noted with colonizing species likely to be more oligotrophic and to have higher indicator values for temperature. This suggests that climate change as well as atmospheric nitrogen deposition are affecting long-term patterns in these mountain hay meadow communities.
