Climate and sea level have drastically altered mangrove distribution since their appearance in the geological record ∼75 million years ago (Mya), through to the Holocene. Historical records show that prior to the 1930s there were no mangroves present. They can selectively absorb only certain ions (electrically charged atom(s) andlor group of atom(s) which a salt becomes on going into solution) from the solutions they come into contact with by a process called ultrafiltration. They also become incredibly important during storms: their roots can help break up wave energy and decrease storm surge. mangrove and the mangrove forest of which it is a part.
