- Global mangrove distributions have fluctuated throughout human and geological history. The area covered by mangroves is influenced by a complex interaction between land position, rainfall hydrology, sea level, sedimentation, subsidence, storms and pest-predator relationships). In the last 50 years, human activities have strongly affected mangrove distributions, resulting in declines or expansions of worldwide mangrove area. Mangroves provide several important ‘free services’ including coastal stabilization, juvenile fish habitats, and the filtration of sediment and nutrients). Mangrove loss has important implications for coastal ecological systems and human communities dependent on healthy mangrove ecosystems. This article presents an overview of global mangrove forest biome trends in mangrove ecoregions distribution, as well as the cause of such changes. As of 2012, mangroves are found in 105 nations globally. Although distributed across 105 nations, the top 10 mangrove holding nations contain approximately 52% of the global mangrove stock with Indonesia alone containing between 26% and 29% of the entire global mangrove stock. The largest continuous area of mangrove forest is likely in-and-around the Sundarbans National Park in India and the Sundarbans Mangrove Forests in Bangladesh, which are both recognized by UNESCO as World Heritage Sites. Although existing almost exclusively in the tropics and near-tropics, warm ocean currents support mangrove forests as far north as Walsingham Nature Reserve (Idwal Hughes Nature Reserve) in Bermuda and as far south as Snake Island, Australia.
