The island of Sri Lanka is approximately 67,654km2 (6,765,400 hectares). This island was repeatedly separated and connected to the southern tip of India during interglacial periods yet the islandâ€™s fauna and flora shows a high degree of endemism. It was estimated that some 25% of the islandâ€™s original vegetation remained fairly intact; one of the most prevalent ecosystems on the island is the mangrove wetland systems. The island of Sri Lanka has several extensive coastal wetlands with rich mangrove forest in past.

Current rates of mangrove destruction are roughly estimated at around 150,000 hectares (370,050 acres) per year, or about 1% per annum, according to the United Nations Food and Agriculture Organization Almost 225,000 metric tons of carbon sequestration potential is lost each year with current rates of mangrove destruction. More than 50 % of the Sri Lanka Mangrove forests have been destroyed irrecoverably in the past 30 years through deforestation, abuse and exploitation â€“ with negative impacts on fishery and the protection against catastrophic flooding events.
