The Mundok Migratory Bird Reserve sprawls over a vast area at the mouth of the Chongchon River covering Ryongo-ri, Tongrim-ri and Soho Workers’ District in Mundok County, South Phyongan Province.
1995, it was designated as a national migratory bird reserve for its important role in protecting migratory birds (waterbirds) in the DPRK and across the world. In 2018, it was inscribed as a wetland of international importance for the first time in the country.
According to the field surveys conducted by the Biodiversity Institute under the State Academy of Sciences, more than 120 000 waterbirds in over 90 species were observed at the reserve.
The surveys also ascertained 13 globally-endangered species of waterbirds and ten species of other waterbirds which account for over one percent of the global or regional population.
