The IBA comprises the estuary of the Krabi river, immediately upstream and downstream of Krabi town, on the west coast of peninsular Thailand. Mangroves cover c.10,200 ha, and have mostly been degraded by logging. Intertidal sand- and mudflats cover a further c.1,200 ha at the river mouth. The site also includes a number of limestone karst outcrops. The site is included within Krabi Estuary Ramsar Site, which was designated in 2001and covers 21,299 ha.
Na Muang Krabi is an important site for migratory waterbirds. The globally threatened Nordmann's Greenshank Tringa guttifer and Chinese Egret Egretta eulophotes are regular winter visitors to the site, while another globally threatened species, Masked Finfoot Heliopais personata, is a regular non-breeding visitor. The site supports resident populations of two globally near-threatened species, Mangrove Pitta Pitta megarhyncha and Brown-winged Kingfisher Halcyon amauroptera, while a third globally near-threatened species, Asian Dowitcher Limnodromus semipalmatus, occurs regularly as a passage migrant. In addition, the site supports of 1% of the Asian biogeographic populations of Common Tern Sterna hirundo and Lesser Crested Tern S. bengalensis. The site qualifies under criterion A3 because it supports one species (Masked Finfoot) restricted to the Indochinese Tropical Moist Forests (Biome 09).
Non-bird biodiversity: No information is available about other globally threatened species at the site.
