How many Ramsar wetlands are there in Sri Lanka?
As of my last update in April 2023, Sri Lanka has six sites designated as Wetlands of International Importance under the Ramsar Convention. These Ramsar sites are significant for their ecological, botanical, zoological, limnological, or hydrological importance. The convention, named after the city of Ramsar in Iran where it was signed in 1971, aims to protect and use wetlands sustainably across the globe. The specific sites in Sri Lanka may have unique characteristics and contribute to the biodiversity and ecological balance of the region.
