A .gov website belongs to an official government organization in the United States. This unique environment allowed for the evolution of a variety of special structures that help the underground roots gain access to air, even when submerged by the tide. Through a series of impressive adaptationsincluding a filtration system that keeps out much of the salt and a complex root system that holds the mangrove upright in the shifting sediments where land and water meet. /Tabs /S There is not a lot of plant diversity (number of species) in mangrove swamps.

A 2013 study found that 71 percent of the forest is experiencing 656 feet (200 meters) of coastline retreat per year, almost the length of two football fields. Pneumatophores are specialized roots that act like snorkels when partially flooded and have pores called lenticels that cover their surface where oxygen exchange occurs. /Type /Group Certain ecosystems store carbon better than others. Mangroves host a few species of crabs that are known to climb trees. Based upon findings that seedlings do best when they are submerged for 30 percent of the time and dry for the remaining 70, Lewis and a team of engineers modified the coastal landscape by moving piles of dirt with bulldozers and backhoes away from the experiment site.
