The lower Songkhram River basin in northern Thailand was declared the next Ramsar site, giving one of the country’s few abundant waterways an international recognition for its rich biodiversity and ecosystem values. Natalie Phaholyothin, CEO of the World Wild Fund for Nature (WWF) Thailand said the lower Songkhram River basin was declared as Thailand’s next Ramsar site under the Ramsar Convention on Wetlands of International Importance on 15 May 2020, making it the 15th site in Thailand.

These lakes are representative of the steppe zone of Northern Kazakhstan. These are fresh water lakes, but when the water level lowers the salt concentration increases. The water bodies have seasonally changing water levels and typical border-curtain or mosaic thick reeds. The lake system is a stop–over site for Siberian Cranes during migration.
