I'm actually doing research on mangroves this July. Mangroves protect coasts from damage due to storms and erosion. They form a refuge and nursery for many marine fish. However, they are under threat from coastal development, logging, and shrimp aquaculture. Between 1983 and the present, half of the world's 45 million acres of mangroves were cut down. Also, rising sea levels due to climate change may destroy many mangrove habitats. Natural threats, such as blooms of the cyanobacteria Lynbgya majuscule, may be causing mangrove die-offs in some areas, while erosion and severe weather destroy habitats in other areas.

Mangroves can protect an area from high wave action, and since they have large root systems, increase deposition of sediment around them. Once established, they support unique communities of organisms, including algae, sponges, bryozoans and bivalves (clams and oysters).

mangroves prevent erosion, and are a natural habitat for lots of wildlife.
