Nanthar Island and Mayyu estuary, one of the six flyway network sites in Myanmar, was also designated as a Ramsar Site in 2020. This area covers around 3600 ha and provides nutrients rich habitat for many migratory birds. The migratory waterbirds include five globally threatened species including perhaps 5% of the global population of the Critically Endangered Spoon-billed Sandpipers. This area has been designated as Marine National Park recently, although still lacks of attention for protection due to limited resources.
