These swampy, stilt-rooted trees store massive amounts of carbon on tropical shorelines, support nurseries for a wide variety of commercially important fish species, and protect coastal areas … Growing in a coastal intertidal zone means that these trees and shrubs must be able to accommodate the rise and fall of the daily tides. With the ability to store vast amounts of carbon, mangrove forests are key weapons in the fight against climate … Red mangroves, together with the other three U.S. mangrove species—black mangroves, white mangroves, and buttonwood—form vast coastal forests. “Mangroves are various types of trees up to medium height and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics – mainly between latitudes 25° N and 25° S. The remaining mangrove forest areas of the world in 2000 was 53,190 square miles (137,760 km²) spanning 118 countries and territories. A mangrove is a shrub or small tree that grows in coastal saline or brackish water.. The complex root systems of these forests protect shorelines from being eroded over time by waves. The huge amount of biomass dissipates the energy of incoming waves and may greatly decrease the impact of hurricanes and tsunamis in coastal areas (e.g. Both the environment and its people receive benefits from mangrove forests and its variety of services. They attract tourists which is a source of foreign exchange. The structure of the roots helps to soften the blow of the waves, which protects any man-made or natural structures on the opposite side of the mangrove. The Sundarbans is the world's largest coastal mangrove ecosystem and spans an area between the Indian and Bangladeshi coasts. Mangrove thickets improve water quality by filtering pollutants and trapping sediments from the land, and they reduce coastal erosion. More than half of the world’s mangrove … The Sundarbans mangrove forest covers an area of about 10,000 km2, of which forests in Bangladesh's Khulna Division extend over 6,017 km2 and in West Bengal, they extend over 4,260 km2 across the South 24 Parganas and North 24 Parganas districts. This results in alternations in both the terrestrial and aquatic food web. Found in coastal areas all over the tropics ; Primarily in brackish water ; salty and fresh mix ; Cover approximately 22 million hectares in tropical and subtropical coasts; 3 Ecosystem Functions Threats. These include that they: 1. 2. Dense mangroves are the common varieties of trees. Provide physical habitat and nursery grounds for a wide variety of marine organisms, such as fish, shrimp and crabs. Tangles of prop roots along the coast trap sediment that moves with the tide, which gradually builds up soil around the plants. Mangroves are extremely important breeding grounds and feeding areas for shrimp and fish. All of these trees grow in areas with low-oxygen soil, where slow-moving waters allow fine sediments to accumulate. In addition, it is at the… Mangroves provide essential habitat and coastline protection but are under threat. There are 80 different species of mangrove trees and shrubs. The total area is nearly 10,000 km2. Florida has approximately 1042.5 square miles (2,700 square kilometers) of mangrove forest, a subtropical coastal ecosystem. The forests provide habitat to 453 faunal wildlife, including 290 bird, 120 fish, 42 mammal, 35 reptile and … Water. Composed of species that are among the few saltwater-tolerant woody plants, mangrove forests occupy coastal areas with saline or brackish water, typically where there are muddy bottoms. [NEW DELHI] Dense mangrove forests growing along the coasts of tropical and sub-tropical countries can help reduce the devastating impact of tsunamis and coastal storms by absorbing some of the waves’ energy, say scientists. 4. While no one lives within the Sundarbans mangrove forest in Bangladesh, the growing population pressure in the periphery leads to the unsustainable use of natural resources when people enter the mangrove forests – some legally (fishing), some illegally (poaching) – to sustain their livelihoods. Mangrove forests are found in coastal intertidal zones at tropical and subtropical latitudes around the globe. 2. This has an effect on the types of refugees available to consumers. Mangrove habitats are of significant environmental and economic importance. 1. Continued mangrove expansion could increase carbon storage along coastlines. Provide food for marine organisms. And they are found in the intertidal regions where freshwater and saltwater intermixes, in the bays, estuaries, creeks, and lagoons. Dahdouh-Guebas et al., 2005). It can grow above 2 meters tall. Mangroves are tropical trees that thrive in conditions most timber could never tolerate — salty, coastal waters, and the interminable ebb and flow of the tide. Reclamation is carried out by both government and private developers. Variations in river and surface run-off, that inhibit the tropical coastal deltas of fresh water and silt, cause losses of mangrove species diversity and organic production. Wood grown in those forests serve as source of fuel for the locals and rural households. Trap and cycle various organic materials, chemical elements, and important nutrients in the coastal ecosystem. Mangrove forests play an important role in a coastal ecosystem. Storing carbon in flooded soils. There are about 80 different species of mangrove trees. Mangrove forests act as natural protection in the case of storms and decrease erosion on coastal areas. Mangroves are coastal forests that grow in the tidewater of tropical and semitropical regions. One of the most important roles of mangrove habitats is their ability to prevent erosion of coastal areas. In some areas, red mangrove roots are ideal for oysters, which can attach to the portion of the roots that hang into the water. Mangroves are a special type of vegetation. Serve as an important buffer between sea and land Live and decaying mangrove leaves and roots provide nutrients that nourish plankton, algae, fish and shellfish. … Mangrove forests are found in the coastal regions which are affected by tides. Coastal area is in serious danger from land reclamation in the Niger Delta, Nigeria. Because mangroves are found so close to the sea, they experience a host of pressures. Those that can handle tidal soakings grow in the open sea, in sheltered bays, and on fringe islands. They are the salt-tolerant variety of plants, which can survive in harsh conditions. Mangrove forests are rich in biodiversity providing a habitat for wide varieties of animal and plant species. Title: Mangrove Forests 1 Mangrove Forests Dr. James A. Danoff-Burg Columbia University 2 Mangrove Forests. The roots of the plants are submerged in water and can be seen only during low tide. Serve as roosting and nesting sites for many of our birds. Mangroves serve as kindergartens for many species Soil reclamation for agric… Economic importance of coastal forests They provide raw materials for paper industry. In coastal areas in the tropics and subtropics, few trees play a more important role than mangroves. What is a mangrove forest? With their dense network of roots and … Australian Mangrove forests contain 41 species of mangrove from 19 plant families. The Mangro ve forest type occurs in many of Australia’s coastal regions, but has a total area of only 0.9 million hectares, or 0.6% of Australia’s native forest cover. Development in the coastal zone also leads to mangrove destruction indirectly through the increased pollution, altered hydrology, and harmful human contact that can result. People will always be engaged in making projects. The main source of these threats are induced by humans. Mangroves grow along shorelines, and they protect coastal areas from erosion and storm surge… Sundarbans is the largest mangrove forest in the world. The most abundant tree species are sundri and gewa. The mangroves are threatened in their existence by several causes. Mangroves range in size from small bushes to the 60-meter giants found in Ecuador. Mangroves are extremely important to the coastal ecosystems they inhabit. Landscape reclamation is intended for urban city expansion, road construction, housing project, crude oil exploration and sand mining. JOHN MWIKYA BSMR/265J/2017 COASTAL FORESTS AND MARINE RESOURCE Question one Explain the economic, social and environmental functions of coastal forests. There are about 110 mangrove species.. Botanists believe that mangroves originated in Southeast Asia, but ocean currents have since dispersed them to India, Africa, Australia, and the Americas.. Mangroves are remarkably tough.Most live on muddy soil, but some also grow on sand, peat, and coral rock. Mangrove forests are tropical forests which are particularly unique as they straddle the sea and land along coastlines. Mangroves are essential to maintaining water quality. Review the following information with students: A mangrove is a small tree or shrub that grows in shallow water along the coastlines in warm, tropical climates. Within a given mangrove forest, different species occupy distinct niches. Only 12 species live in the Americas. Such habitats are similar to salt marshes in the temperate zone. The Ten Thousand Islands area, including Ten Thousand Islands National Wildlife Refuge, is comprised of about 232 square miles (600 square kilometers) of mangrove forest, making Southwest Florida home to one of the world’s largest mangrove systems. They are dynamic areas, rich in food. Mangrove forests only grow at tropical and subtropical latitudes near the … As coastal populations continue to grow and coastal tourism increases, mangroves are cleared to make way for infrastructure, businesses, hotels, and homes. And they are economically and ecologically significant. This is because of land expansion activities such as urban development. Physically, they serve as a buffer between marine and terrestrial communities and protect shorelines from damaging winds, waves, and floods. View of mixed mangrove forest on drier ground alongside a small coastal river. Serve as storm buffers by reducing wind and wave a… Red mangroves grow at sea level right along the shore. Branches of the mangroves act as bird rookeries and nesting areas for coastal wading birds including egrets, herons, cormorants and roseate spoonbills.
