What is a mangrove forest and what is its ecological and economic importance? Value is determined in these markets through exchange and quantified in terms of price. The tsunami has provided an opportunity to illustrate that healthy mangroves serve as a natural barrier against massive waves â protecting infrastructure developments and saving lives. While mangroves in the Caribbean have been demonstrated to support juvenile coral reef fish, mangrove ecosystems in Papua New Guinea and the Solomon Islands have been found to provide important nurseries for sandy and muddy-bottom demersal and surface feeding species. Value is determined in these markets through exchange and quantified in terms of price. At high tide, fish move in to feed among the protection of mangrove roots, turning the marshy land into rich fishing grounds. Freshwater swamps are usually found near lakes and streams where seasonal floodwaters or rain saturates the land with water. The mangrove population has felt both direct and indirect effects due to coastal engineering and human development, resulting in a devastating decline in population. Historically the responsibility of mangrove management at the national level in many tropical mangrove countries have been assigned on a sectoral basis to executing agencies of the government, institutions for example Forestry, Fishery or Agriculture Departments. Swamps were also considered to be wastelands that had little or no use. These wetlands are often found in estuaries, where fresh water meets salt water and are infamous for their …  In Selangor, Malaysia 119 species were recorded as associated with mangrove ecosystems while 83 species were recorded in Kenya, 133 from Queensland Australia, 59 species in Puerto Rico and 128 from the Philippines. According to  a comprehensive information database of mangrove biodiversity in each country is necessary to monitor the status of mangrove biological diversity, realise its economic potential and areas of application. Coal is formed from plant matter that accumulated for a period of millions of years. A mangrove commonly refers to two different things: a tidal swamp ecosystem found in tropical deltas, estuaries, lagoons or islands, and the characteristic tree species populating this ecosystem.  In addition, mangroves protect intertidal sediment along coastlines from eroding away in harsh weather year-round. An immense variety of species of microbes, plants, insects, amphibians, reptiles, birds, fish and mammals can be part of a wetland ecosystem. Massive tracts of swamps have disappeared in recent decades only to be replaced by human settlements and farmlands. At low tide, people can walk across the tidal flats to collect clams, shellfish, and shrimp. The World Conservation Union (IUCN) compared the death toll from two villages in Sri Lanka that were hit by the devastating tsunami giant waves. Many migratory species depend on mangroves for part of their seasonal migrations. Mangroves are trees or shrubs that grow in salty water in hot places like the tropics.Mangroves make a special saltwater woodland or shrubland habitat, called a mangrove swamp, mangrove forest, mangrove or mangal. Mangrove swamps are coastal wetlands found in tropical and subtropical regions. This type of ecosystem supports crabs, shellfish, and a variety of other marine and coastal fauna.  Other factors mangroves have an influence on, include coastal profile, water depth and bottom configuration. The increasing losses from tropical cyclones in developing countries highlight the importance of understanding how natural habitats can be used to protect assets and economic activity against this hazard. Climate, landscape shape (topology), geology and the movement and abundance of water help to determine the plants and animals that inhabit each wetl… Fish is one of these important products. Mangrove Restoration practices have also greatly improved over the past several years. Additionally, mangrove forests are often a rich source of timber, fuel wood, honey, medicinal plants and … Two people died in the settlement with dense mangrove and scrub forest, while up to 6,000 people died in the village without similar vegetation  This study proves that mangroves provide a natural wall, which is necessary in high impact natural disasters areas such as this one.
