Estuaries and wetlands support important ecosystems and can also protect surrounding areas from foods and tidal storm surges. When flooding does occur,

estuaries and wetlands soak up excess pollution and then niter the water through sand and other sediments into the groundwater or river system. They also

control erosion with water that holds soll in place. Following a food, the plant matter from wetlands feeds many species further down the river

system. Estuaries contain species that are tolerant to changes in the amount of salt in the water. Tidal wetlands form downstream from estuaries and are

considered nurseries for birds, fish, and shellfish.
