One of Sri Lanka's finest ecologically valuable discoveries stretches along the western seaboard in Muthurajawela Wetlands. It stretches to 6,000 hectares and is internationally known due to its high level of biodiversity together with the cultural and historical considerations with which it is associated. Etymology "Muthu,,," (from Sinhalese- pearl) and "Raja Wela" in the same language, meaning Swamp of the King, reflects on Muthurajawela as the Treasure of the Swamp of Royal Interest, justifiably so.
Muthurajawela is about 30 km north of Colombo, hence it is a green lung for the densely populated capital region. It also serves as a natural barrier against flooding and seawater intrusion which indicates its role in environmental sustainability.
