Importance of Estuaries What is an Estuary? The word estuary is derived from the Latin word "aestuarium" meaning tidal inlet of the sea, which in itself is derived from the term "aestus", meaning tide.

Estuarine plants also can
absorb tide and storm surges. What Challenges Do
Our Estuaries Face? Too many nutrients Toxic Chemicals Invasive Species Pathogens Changes in Waterflow Habitat loss and change by: Kaye Cebele Gonzales The productivity and variety of estuarine habitats support a wonderful abundance and diversity of species. The transition character of estuaries provides important research value for scientists.
