Port Launay Coastal Wetland, das erste Mangroven Gelände der Seychellen, das seit 22. November 2004 dazu bestimmt ist, die Küste von Port Glaud mit einer Fläche von 121 Hektar zu schützen. Das Port Launay Küstenfeuchtland ist eines der besten Mangroven-Feucht-Biotope auf der Hauptinsel Mahé, in der es alle sieben Mangrovenarten der Region gibt. Die Mangroven entlang der Küste helfen die Küste zu stabilisieren, und die Hochlandgebiete des Geländes, Granitgebiete mit hoher Drainage, spielen eine große Rolle in der einheimischen Hydrologie.
The coastal area provides ideal spawning grounds, nursery, food and hiding place for fish and is also home to some of the Seychelles' endemic species, such as the goujon (Seychelles killifish), and the freshwater fish Macanbale. The habitat provided by the site is also said to be important for the little known Seychelles Pocket Bat, of which only four active roosting caves are known, one of which is in the area, and for the Seychelles fruit bat. Both belong to the critically endangered species.
In the tributaries to the wetland, live some endemic species of lobster. Fishermen use this area to fish for octopus.
The site is often used for educational activities for school children, especially around the World Wetlands Day.
