Floodplains are challenging to survive on!
Although floods replenish soil nutrients, they also create regular disturbance, so only plants that can tolerate repeated inundation, soil saturation, and flood damage occupy the margins of streams. Green ash trees, for instance, have incredibly wide-spreading roots1 that enable them to maintain a hold in this environment. Small plants that thrive in these floodplain soils must also be either extremely well-rooted, or able to grow fast enough to mature and produce seed between floods in which they are often flattened, buried by debris, or swept away.
