Local flooding history affects plant recruitment in riparian zones
Abstract Aims Many rivers across the globe are severely impacted by changed flooding regimes, resulting in drastic shifts in vegetation, but the processes driving the exchange of flood‐sensitive and flood‐tolerant species are understood less. We studied the role of long‐term and recent flooding hist...

Further, lowest seedling numbers were observed when the previous flooding occurred in winter, and higher seedling numbers when floods occurred in spring or not at all. Conclusions Both long‐term and recent flooding histories can affect plant recruitment, and their influence should be taken into account when designing restoration projects.
