Mangrove forests are found in coastal regions. They have adapted themselves into salty waters in the following ways:

  • Mangroves need to breathe. . Mangroves have multiple sets of roots--the underground roots in addition to aerial (above-ground) roots that take in oxygen through tiny pores called lenticels.
  • Mangroves survive in salty waters. Some mangroves use is to filter salt out through their roots. This way, they only absorb the fresh water and use that to hydrate themselves. Another strategy is to absorb the salt in their bark, which they eventually shed.

Mangrove forests are under threat and we need to protect them because they play an important role in the environment. They provide food, fisheries and freshwater. They also reduce the impacts of flooding. Mangrove forests add diversity to the world’s flora.
