Some mangrove species live so close to the shoreline that they are flooded with salt water every day as the tide comes in and submerges their roots. Decomposers clean up the dead material by processing it and returning the nutrients to the soil for the producers.

Mangrove can also be used as a term that refers to an entire community. Throughout the night the bats will travel tree to tree and the pollen is transferred to flowers of different individuals. This process helps provide organic nutrients for the ecosystem where it lives. Although mangrove populations have flourished in that last 6,000 years, a past change in sea level during the retreat of the glaciers roughly 20,000 years ago, potentially killed a majority of their population. >> Their importance lies in their ability to aggressively degrade lignocellulose.

In most cases, they approach mangrove restoration as if they were planting a forest on land. Perhaps, the initial few seedlings to colonize the north were extremely early reproducers and the trait has been passed down to the current generation.
