Floodplains Boost Salmon Growth and Survival

Studies in California reveal how important active floodplains are for salmon productivity and growth, in addition to providing flood protection and seasonal agricultural land. Juvenile salmon that spend time on the floodplain grow faster than those that use only the river channel during their migration to the ocean, according to Carson Jeffres, fish ecologist for the UC Davis Center for Watershed Sciences. This increase in productivity on the floodplain is because the water is warmer and food is more abundant.  Because of the increased growth, the juvenile salmon are larger when they head out to sea and can survive better by swimming faster and avoiding predators.
