Most mangroves grow on public land, only about 1 percent of which receives any sort of protection. Mangrove forests, consisting of multiple taxa of tropical macrophytes, are distributed mainly in tropical and subtropical regions of the world [1,2,3].The upper latitudinal limits of global distribution, extending into the temperate regions, are characterized by decreased abundance, reduced species diversity, and decreased tree vigor, growth, and biomass (Figure 1). Threats to mangrove forests and their habitats include: “More countries are now recognizing the importance of mangroves and are making an effort to conserve and better manage them,” said Mette Løyche Wilkie, a mangrove expert at FAO. Sundarbans is the largest mangrove forest in the world.

Mangrove forests and “swamps” are important as spawning grounds and nurseries for marine and freshwater species. “Yet the true value of mangroves and other wetlands is still underestimated and much remains to be done to reduce the rate of loss, which is significantly higher than for other forest types,” she added. Long term survival of mangroves is at great risk because of fragmentation of the mangroves. The report, to be published next January, will provide an overview on mangrove vegetation and species, uses and threats in addition to information on mangrove areas and area changes over time. Despite this hardiness, mangroves cannot withstand cold temperatures and can only be found in These forests provide at least US$1.6 billion each year in ecosystem services. The figure is as high as 50% in countries such as India, the Philippines, and Vietnam, while in the Americas they are being cleared at a rate faster than tropical rainforests.
