"Mangroves are among the most biologically important ecosystems on the planet, and a common feature of tropical and sub-tropical coastlines. But ground-based evidence suggests these vital coastal forests have been strained in many regions because of harvesting for food, fuel, and medicine.

Now, scientists have used satellite images to compile the most comprehensive map of mangroves worldwide, which should help in future efforts in monitoring and conservation.

Mangrove forests are typically made up of trees, shrubs, and palms that have adapted to the harsh conditions of high salinity, warm air and water temperatures, extreme tides, muddy, sediment-laden waters, and oxygen-depleted soils.

They are fertile nurseries for many marine species, and also serve as a first line of defense against hurricanes and tsunamis by dissipating wave and wind energy."
