Fringed by tropical rainforest and coral reefs, the clear-water mangroves of Raja Ampat, Indonesia are the filtration plan of the ocean. Mangroves trap sediments flowing down rivers and off the land; without the mangroves, coastal reefs would be smothered by the runoff, blocking off the vital sunlight that the coral needs for growth.
The dense root systems of a mangrove forest protect the coastline from erosion from storms, are home to a large variety of fish, crab, shrimp, and mollusk species, and provide a vital nursery for many reef and pelagic fish species as well.
A study on the Mesoamerican reef, for example, showed that there are as many as 25 times more fish of some species on reefs close to mangrove areas than in areas where mangroves have been cut down. This makes mangrove forests vitally important to coral reef and commercial fisheries as well.
