Mangrove

Mangroves are a group of trees and shrubs that live in the coastal intertidal zone. There are about 80 different species of mangrove trees. All of these trees grow in areas with low-oxygen soil, where slow-moving waters allow fine sediments to accumulate.

Biology

Mangrove trees are able to absorb much higher amounts of salt than typical trees. They are able to do this through a filtration system that is in their roots. The roots also take in oxygen from the air, as the soil they grow in is often depleted of oxygen.

Distribution

Mangroves are found in the tropics and subtropics, mainly between latitudes 25° N and 25° S. The total mangrove forest area of the world in 2000 was 137,800 square kilometers (53,200 sq mi), spanning 118 countries and territories.

Ecological importance

Mangroves play a crucial role in maintaining the health of coastal ecosystems. They provide habitat for a wide range of species, including birds, mammals, and fish. In addition, they help to protect coastlines from erosion and storm surges.

Threats

Mangroves are under threat from a variety of factors, including deforestation, pollution, and climate change. These threats have led to significant declines in mangrove populations in many parts of the world.

Conservation

Efforts are being made to conserve and restore mangrove forests. These efforts include the establishment of protected areas, the implementation of sustainable forestry practices, and the promotion of community-based conservation initiatives.
