Land was reclaimed for harbours and filled in for pasture, sewage schemes and rubbish dumps. Estuaries provide a wide variety of habitats and wildlife and significant commercial and recreational benefits. Salt marsh grasses and other estuarine plants help prevent erosion and they stabilize shorelines. They are sheltered homes to many species of plants and animals that like to live in water that is part fresh water and part salty waters. What makes this habitat different? Salt marsh grasses, mangroves and other estuarine plants also help prevent erosion and stabilise the shoreline. Nutrients are taken up by plants or recycled by sediments. They contain a wide range of habitats and ecosystems including large areas of open water, rocky reefs, unconsolidated bed sediments, intertidal sand and mud flats, mangroves, saltmarshes and temperate seagrass beds. Estuaries are among the most productive environments on earth, creating more organic matter each year than similarly-sized forests and agricultural areas. As the water flows through the wetlands and marshes, all the pollutants are filtered out. Estuaries are one of the most important of the state's natural resources and are some of the most intensively used areas of NSW. Estuaries are often the cultural centres of coastal communities and serve as the focal point for local commerce, tourism and recreation activities.

Estuaries provide us with a range of resources and services. A healthy estuary produces more food per acre than the richest Midwestern farmland. This can be sped up by land clearance for urban living and industrial development that exposes soils, leaving them vulnerable to being washed away. Many also have special significance for local indigenous people. Estuaries are also important to keep our oceans healthy. Estuaries also have other important values. Estuaries provide places for recreational activities and scientific studies. These unique coastal environments also provide aesthetic enjoyment and the proven health benefits of green space for the people who live, work or visit estuaries for the many recreational activities. 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. Estuaries are an irreplaceable natural resource that needs to be carefully monitored so that the animals and plants that depend on them are thriving. Due to estuaries being biologically productive, migratory birds use them as places to rest and re-fuel. It occurs when rain, rivers and streams wash sediment off the land and into estuaries. This protects land based organisms as well as valuable real estate from storm and flood damage. Eventually, s… ... he entered the river in 1609. More than two-thirds of the fish and shellfish consumed by humans spend some part of their lives in estuaries. Why are estuaries so important? This protects the upland habitat as well as valuable real estate. Estuaries provide people with many opportunities for recreation including boating, fishing, swimming, diving, windsurfing and bird watching. More than one-third of the United States' threatened and endangered species live only in wetlands, and nearly half use wetlands at some point in their lives. Wetlands occur in different environments around the world, but they all have one thing in common: they are extremely important habitats of rich biodiversity, and they have an important role to play in the lives of humans and animals alike. importance of estuaries. Estuaries are among the most biologically productive ecosystems on the planet. Some can be measured in dollars and others cannot. Population growth and coastal development are two of the key causes of threats to our estuaries. Estuaries are important for many reasons. Estuaries are important sites of nutrient recycling in the coastal environment. Wetland plants and soils also act as a natural buffer between the land and ocean, absorbing flood waters and dissipating storm surges. They depend on them to live, feed and reproduce. They are important to the economy because they benefit tourism. As well as being one of the most productive ecosystems, estuaries are also one of the most threatened ecosystems (NOAA, 2012).

Humans are diverting water from rivers and streams, decreasing the amount of flows making it to estuarine ecosystems. The protected waters provide vital nesting, breeding and feeding habitats for many species. Millions of people visit estuaries each year to boat, swim, fish, and watch birds and other wildlife. Estuaries and their surrounding wetlands are also buffer zones. This includes recreation, scientific knowledge, education and visual values. More than two thirds of the fish and shellfish we eat spend some part of their lives in estuaries. Spawning organisms make reefs and estuaries their home because animals can find abundance of food and excellent protection from predators. Their resources provide tourism, fisheries and recreational activities to have a greater economic benefit. Tens of thousands of birds, mammals, fish and other wildlife depend on estuarine habitats as places to live, feed and reproduce. Many are threatened species. 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. Estuaries provide ideal spots for migratory birds to rest and refuel during their journeys. Why Are Wetlands Important? An immense variety of species of microbes, plants, insects, amphibians, reptiles, birds, fish and mammals can be part of a wetland ecosystem. These freshwater inputs often have additional nutrients compared to the natural situation because they receive wastes from cities towns and farms.
