Mangroves live along subtropical and tropical coastlines. Their upper trunk, branches and leaves grow above the waterline, but an extensive network of roots remain mostly underwater. Dense patches or forests of mangroves are habitats for terrestrial, estuarine and marine species that include invertebrates, fish and many types of seabirds and waterfowl, and they provide shelter as well as feeding and breeding space for 174 marine megafauna species. Mangrove forests provide also protect coastlines against erosion and flooding and help mitigate climate change.
