They are the principal recreational areas of most of the nation's largest cities - such as Boston, New York, Baltimore, Los Angeles, and San Francisco. Estuarine habitats also protect streams, river channels, and coastal shores from excessive erosion caused by wind, water, and ice. It occurs when rain, rivers and streams wash sediment off the land and into estuaries. Māori viewed estuaries as productive food gardens and often actively protested when sewage and stormwater were discharged into estuaries. They are home to unique plants and animals that have adapted to the brackish water that develops where fresh and salt-water systems come together. For this reason, estuaries are some of the most fertile ecosystems on Earth. They have many benefits for humans and animals. These provide protected harbors for shipping and have developed *DonaldW. Cultural values. Tens of thousands of birds, mammals, fish, and other wildlife depend on estuarine habitats as places to live, feed, and reproduce. Estuaries support up to five times as many bird species as an equivalent area of native bush. As water flows through a salt marsh, marsh grasses and peat (a spongy matrix of live roots, decomposing organic material, and soil) filter pollutants such as herbicides, pesticides, and heavy metals out of the water, as well as excess sediments and nutrients. It often forms at the mouth of a river, with large mud flats where the tides wash in and out. They also have other ecosystem uses, such as pesticides. Tides carry in nutrients that stimulate plant growth in the marsh and carry out organic material that feeds fish and other coastal organisms. Here are some interesting facts about estuaries: Nearly 75% of all of the fish and shellfish harvested come from the rich resources found in coastal estuaries. Why are estuaries important to humans? They stabilize shorelines and protect coastal areas, inland habitats, and human communities from floods and storm surges from hurricanes.
