This is likely to increase into the future due to climate change. The construction of waterway barriers such as dams, weirs, barrages and stream crossings on waterways are listed as a serious threat to fish movement within the waterway. Barramundi juveniles use coastal swamps, marine plains and flood plains as nursery areas. Their dense roots help bind and build soils. The heavy scouring of sediment will eventually result in the uprooting and loss of mangrove trees. Ponded pastures may also result in fish kills. Diurnal or daily flows may also be altered by major daily peaks associated with the demand for irrigation water. Mangroves protect shorelines from damaging storm and hurricane winds, waves, and floods. Responsible for total loss of mangrove habitat in some locations, urban development includes the construction of buildings and canal systems as well as the consumption of water by a growing human population. Natural structures like marshes, mangrove stands, coral reefs and oyster reefs can help protect Florida's coastline from storm surge and sea-level rise. These volunteers plant mangroves on the Blowing Rocks Preserve shoreline as part of their field trip. Human Impacts Dredging. Mangroves have long been associated with human populations, as coastal communities rely on the various ecosystem services that mangroves provide. Mangrove areas in some Pacific Island countries are high relative to their land area, such as 12% of the Federated States of Micronesia, and 10% Waterways often carry toxic loads of nutrients, heavy metals, pesticides and contaminants from previous activities that involved sewage plants, For example, three water hyacinth plants may produce 3000 new plants in 50 days. Swimming in the seas that reach East Africas mangrove swamps can be found the dugong, a vulnerable marine mammal that is often mistaken for its cousin, the manatee, due to its gray appearance and oblong body. The same report estimated that worldwide, mangroves reduce risk to more than 15 million people and prevent more than $65 billion in property damages each year. Weirs often have social, aesthetic and even heritage values to the local community.
