Mangroves are the most carbon rich forest in the tropics and soils are high in carbon. In the tropics, along the coastline mangroves live where many people want to live and hence the amount of land they grow on has declined by 30 to 50 % over the past 50 years. In most forests, sediment and litter decay rather quickly, but in mangrove forest there is not enough oxygen to break down the litter so the breakdown of material is much slower and this means more CO2 storage. Daniel Donato (US Agriculture Department) reported that tropical mangroves are better at storing CO2 from atmosphere two to four times more than tropical rain forest store and its storage is mostly on that thick organic muck layer in the soil. In India, mangroves account for about 5 percent of the world's mangrove vegetation and are spread over an area of about 4,500 km2 along the coastal States. Mangroves are highly localized in Kerala, but the species diversity and their associates are comparatively rich.
