Natural resources used by humans in estuaries. Some of these are scallops, scams, and oysters. Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. Following this, we have used the Ecosystem Services Approach as a means of quantifying the potential benefits of a well-functioning and Estuaries also have other important values. Many species of fish and shellfish rely on the sheltered waters of estuaries as protected places to spawn, giving them the nickname "nurseries of the sea.". Water draining from upstream areas bring down sediments, nutrients and other pollutants to estuaries. In excessive amounts, however, nutrients cause a type of pollution called eutrophication. As the water flows through the wetlands and marshes, all the pollutants are filtered out. The estuaries serve as great ecosystems for humans, but the estuaries themselves are at risk of pollution. Estuaries are also the beneficiaries of energy subsidies through the tidal transport of food and nutrients and removal of wastes. TIDE presents an overview of demand and supply of ES in four North Sea estuaries (Elbe, Weser, Humber, Scheldt), including maps of many estuarine ecosystem services.

Particularly significant are the submerged aquatic plants and the vegeta­ tion supported by the adjacent wetlands, both of which supply much of the plant detritus basic to the estuarine food web.3. Hundreds of marine organisms, including most commercially valuable fish species, depend on estuaries at some point during their development. Sedimentation smothers the seabed, killing mud-dwellers that can’t burrow up quickly and disturbing the delicate balance of life in the estuary. Tourism, fisheries, and other commercial activities thrive on the wealth of natural resources estuaries supply. Although the benefits of estuaries continue to be vitally important to the economic and ecological health of Florida, the past 60 years have not been kind to the Indian River Lagoon. Estuaries provide places for recreational activities and scientific studies. They stabilize shorelines and protect inland areas from storm surges, flooding, and erosion. A freshwater inflow is the water that flows from streams and rivers into estuaries, mixing with the marine waters. Estuaries are an irreplaceable natural resource that needs to be carefully monitored so that the animals and plants that depend on them are thriving. Estuaries are critical for the survival of many species. Estuaries also reduce the impact of floods and storms by acting like sponges that soak up excess water and keep it from reaching land. Estuaries are delicate ecosystems that serve as natural filters for runoff, and habitat for many species of birds, fish, and invertebrates. Without estuaries, our shorelines would have no protection and would wash away with tides and waves.
