Mangroves are amphibious wooded formations that are commonly found in
tropical and subtropical coastal regions. They develop where the ground is
salty and muddy and exposed to the changing tide. They consist of various
halophyte plants (plants able to grow in soil with high salt contents).
They exist in four continents, covering a total area of 105,570 square
miles (170,000 km2), that is, almost 25% of the world's coastal
New Caledonia, the group of islands in the Pacific over 11,535 square
miles (18,575 km2), includes 124 square miles (200 km2) of a
rather shallow mangrove (25 to 30 feet), but it is very dense, especially
along the west coast of the largest island,
In certain places on land-where seawater is only present at high
tide-vegetation is replaced by barren and salty stretches of land, known
as tannes. These are abundant in the areas surrounding the city of Voh,
where nature has drawn a clearing in the shape of a heart.
biological diversity, the mangrove is a fragile that undergoes the
pressures of various human activities: overexploitation of natural
resources, agricultural expansion, coastal, urbanisation, pollution, etc.
