White Mangroves (Laguncularia racemosa) often grow even farther inland with no outstanding root structures. Shantelle Friesen One study lists global mangrove carbon storage at 75 billion pounds (34 million metric tons) of carbon per year. /ProcSet [/PDF /Text /ImageB /ImageC /ImageI] >> /Subtype /Link In fact, the various species of mangroves aren't necessarily closely related to one another, but they do share the unique capability of growing within reach of the tides in salty soil. They flaunt the enlarged claw to not only attract females but to intimidate male rivals. Using their claws, they move the mud onto mounds aboveground, in some cases up to three meters tall. A stilt root grows toward the soil, arcing away from the central trunk like a flying buttress. When most tree species take about 8 to 15 years to reach a reproductive age, these seedlings take just one year. << /Font << /ExtGState << /StructParents 0 Decomposers - National Geographic Society Estuary - a partially enclosed body of water where two .

And in the Gulf of California in Mexico, mangroves provide habitat for about 32 percent of the local fishery landings, an equivalent of 15,000 dollars per acre. Although there are a few places where mangrove cover appears to be increasing, between 2001 and 2012 the world lost roughly 35 to 97 square miles of mangrove forest per year.

If one or more of those nutrients disappears, the producers, and by extension the whole ecosystem, is in trouble. Mangroves and fish populations are so intertwined that the loss of one square mile of forest will cause a loss of about 275,000 pounds (124 metric tons) of fish per year, the same weight as a small blue whale. /Resources << Larger predatory fish, turtles, and crabs feed on the primary consumers.
