After 7 years, all three of Floridas mangrove species naturally re-established. During past changes in sea level, mangroves were able to move further inland, but in many places human development is now a barrier that limits how far a mangrove forest can migrate.

What threats do they faceand how can we conserve them? It turns out mangroves impact many aspects of peoples lives, not just the houses they dwell in. /Tabs /S People who live in mangrove forests often rely on fishing to make a living. Over several years a toxic sludge accumulates on the bottom of a shrimp pond and regardless of a farmers efforts to clean and maintain the pond, it will eventually be abandoned.

Nutrients like carbon, nitrogen and phosphorous are key to the health of plants. In 2006, two nearby archipelagos were washed away, an illustration that the threat of the entire forest vanishing beneath the ocean is a real concern. Upon visiting the South American coast in the mid 1400s, Amerigo Vespucci named present day Venezuela, which translates to little Venice, because the stilt dwellings that sat over the water within the mangrove forest reminded him of the Venice canals. Initially toxic from the deep, acidic soil coming into contact with the air, the mounds eventually lose their acidity and become excellent places for little mangroves, including several species of the mangrove fern. They raise the young in nurseries, taking turns caring for their own as well as others' offspring and protecting them fiercely. /XObject << Dive underwater in the surprisingly clear waters that typify many mangrove forests, and amangroves smooth brown rootssuddenly take on the textures and hues of the multitude of marine organisms clinging to its bark.

Mangroves are a variety of species of broad-leaved trees (10-40 feet high) lying in muddy creeks and tidal estuaries. This is called blue carbon.

They are also important because they provide a habitat for other species that live in the ecosystem, like fish and birds. They stabilize shores by trapping sediments and building land. As the trees grow they take the carbon from carbon dioxide and use it as the building blocks for their leaves, roots and branches. >> /GS8 47 0 R Mangroves are groups of salt-tolerant, partially submerged trees with sturdy root systems.
