| Earth From Above series. A mangrove swamp is an amphibious tree formation common to tropical and subtropical coastlines. Arising on muddy salt flats exposed to fluctuating tides. It consists of various halophytes (plants that can live in salty soils), with a predominance of mangroves. These swamps are found on four continents, covering a total area of 65,000 square miles, or nearly 25 percent of the world's coastal areas. French New Caledonia, a group of Pacific islands covering 7,000 square miles, has 80 square miles of a fairly low(25 to 33 feet) but very dense mangrove swamp, mainly on the west coast of the largest island, Grande-Terre. At certain spots in the interior that are not reached by seawater, except at high tides, vegetation gives way to bare, oversalted stretches called tannes, such as this one near the city of Voh, where nature has carved this clearing in the form of a heart. Rich in biodiversity, the mangrove swamp is a fragile habitat, under considerable pressure from various human activities; overexploitation of natural resources, droughts, agricultural expansion, urbanization of the coastline, and pollution.
