Facts about Manglier/Mangroves
Once upon a time Manglier/Mangroves 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 the continents. 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 forests. Mangrove trees were historically extensively exploited for its bark and timber – Today a few mangroves forest in Seychelles can be found on,
Port Launay, Cascade, Au Cap, Pointe Larue, South of Mahe, Victoria.
Cote d’Or, Anse Kerlan; Aldabra; Curieuse and a few other islands.

(2010) for details Mangrove trees were historically extensively exploited for its
bark and timber -mangroves are no longer directly exploited.
Mangroves on the
developed islands are still extensively fished for fish and crab on a leisure noncommercial basis.
