Mangrove Tree

A mangrove is a tropical marine tree. Mangroves have special aerial roots and salt-filtering tap roots which enable them to thrive in brackish water. Brackish water is salty but not as salty as seawater.

Mangrove trees are commonly planted and found in coastal areas. Mangroves can serve as walls of protection for natural disasters in coastal areas like a tsunami.

According to BBC News, healthy mangrove forests had helped save lives in the Asia disaster tsunami and people tended to respect these natural barriers even more, especially after the tsunami.

There are several species of mangrove trees found all over the world. Some prefer more salinity, while others like to be very close to a large freshwater source such as a river.

Some prefer areas that are sheltered from waves. Some species have their roots covered with seawater every day during high tide.

Other species grow on dry land but are still part of the ecosystem. The Times of India reported that rare species of mangrove had been found and was also known as the looking-glass tree, probably because the leaves are silver-coated.

Mangroves need to keep their trunk and leave above the surface of the water. Yet they also need to be firmly attached to the ground so they are not moved by waves.

Any part of the root that appears above the water flows oxygen to the plant's underwater surface. as the soil begins to build up, these roots procedure additional roots that become embedded in the soil.
