Estuaries are important sites of nutrient recycling in the coastal environment. Humans are diverting water from rivers and streams, decreasing the amount of flows making it to estuarine ecosystems. Significance of Estuaries for Wildlife Excluding the commercial fishery resources, estuarine wildlife can be classified into four categories, with differing economic and social significance: (1) fur-bearing mammals, (2) game water fowl, (3) other shore and water birds, and (4) the common wildlife that can tolerate human presence. Establishing new parks and protected areas, Current park closures, fire and safety alerts. Without estuaries water erosion will wash away the coast line where rivers meet the sea.Estuaries filter out the silt that flows down the rivers which could otherwise harm wildlife that lives close to the coast.For us humans it provides natural harbours. Notable estuaries include Mobile Bay, Chesapeake Bay, San Francisco Bay, Tampa Bay, New York Harbor, Long Island Sound, Puget Sound, and our own Indian River Lagoon.

Many marine organisms, especially fish used in commercial fishing, depend on estuaries at some time in their life. Tourism, fisheries, and other commercial activities thrive on the wealth of natural resources estuaries supply. Estuaries provide habitat and feeding grounds and for many fish, birds, shellfish, mammals and other wildlife. This can be sped up by land clearance for urban living and industrial development that exposes soils, leaving them vulnerable to being washed away.

Why are estuaries important? Estuaries are critical for the survival of many species. These freshwater inputs often have additional nutrients compared to the natural situation because they receive wastes from cities towns and farms. Major ancient civilizations grew along deltas such as those of the Nile and the Tigris-Euphrates rivers, with the inhabitants of these civilizations learning how to live with their natural flooding cycles. Estuaries also have economic … This filtration process creates cleaner and clearer water, which benefits both people and marine life. They are important to the economy because they benefit tourism. Many also have special significance for local indigenous people. Estuaries and their surrounding wetlands are also buffer zones. Historically, estuaries have developed as urban centres because of their location on historical transport and shipping routes.

Humans also rely on estuaries for food, recreation, jobs and coastal protection. As transition zones between land and water, estuaries are invaluable laboratories for scientists and students studying the complexity of biology, geology, chemistry, physics, history and social issues. Natural resources used by humans in estuaries. Estuaries are an irreplaceable natural resource that must be managed carefully for the mutual benefit of all who enjoy and depend on them. Climate, landscape shape (topology), geology and the movement and abundance of water help to determine the plants and animals that inhabit each wetland. It occurs when rain, rivers and streams wash sediment off the land and into estuaries. Wetland plants and soils act as natural barriers between the land and ocean, absorbing flood waters and the run through from storms.

Estuaries are among the most biologically productive ecosystems on earth. Land was reclaimed for harbours and filled in for pasture, sewage schemes and rubbish dumps. Estuaries also filter pollutants out of the water flowing through them, including pesticides, herbicides and heavy metals. Estuaries provide a nursery for the larval forms of some marine fish species, and provide shelter and food for many young and adult fish and shellfish. They stabilize shorelines and protect coastal areas, inland habitats, and human communities from floods and storm surges from hurricanes. An estuary that is being used as a port or harbor.
