Climate-change projections suggest large changes in riverine flow regime, which will likely alter riparian communities. In northern Europe, forecasts propose lower annual spring flood peaks and higher winter flows, resulting in narrower riparian zones. To estimate the impact of climate change on habitat extent of riparian plants, we developed a framework estimating the sensitivity and exposure of individual species to streamflow change, and surveyed five reaches along the free-flowing Vindel River in northern Sweden. We modeled the hydrologic niche of riparian plant species based on the probability of occurrence along gradients of flood frequency and duration, and used predicted future water-level fluctuations (based on climate models and IPCC emission scenarios) to calculate changes in flow-related habitat availability of individual species. Despite projected increases in run-off, we predict most species to decrease in riparian elevational extent by on average 12−29% until the end of the century, depending ... : species_dataFile with data on species presence and absence in plots at different riparian elevations at sites along the Vindel River in northern Sweden. Species names and inundation data for the plots are explained in a separate worksheet. Refer to the associated paper for explanation of the inundation data and scenarios for the future. ...
