Facts about Manglier/Mangroves
Once upon a time ‘Manglier’ or ‘Mangrove’ was used to shine the wooden floors
of the Seychelles houses. When French settlers first arrived in the remote islands
of the Seychelles, thick mangrove forests fringed the western shore of Mahe Island.
‘Mangroves are salt-tolerant trees, also called halophytes, and are adapted to life
in harsh coastal conditions. They contain a complex salt filtration system and
complex root system to cope with salt water immersion and wave action. They
are adapted to the low oxygen conditions of waterlogged mud.’
Mangroves are one of the most underappreciated and important of the world’s forest ecosystems.
The coastal forests once occurred along the tropical and subtropical coasts of all
Over 80 species of mangrove trees have been described, and the trees are
remarkably important to the functioning of the surrounding ecology. The forests
are a home to numerous species of fish, bird and plant, and it is estimated that
over 75 percent of commercially caught fish spend at least some time in the
mangroves or depend on food webs that are associated with these coastal
Mangrove trees were historically extensively exploited for its bark and timber –
