DMZ, Demilitarized Zone

The ecosystem of the DMZ

The DMZ was established on July 27, 1953, when the Armistice Agreement was signed, dividing North and South Korea. Since then, the demilitarized zone (DMZ) has been preserved in a pristine natural state for the last 60 years.

The DMZ stretches 155 miles (248 kilometers) from west to east and is 4 kilometers wide. Its total surface is 992 square kilometers and it runs across the center of the Korean peninsula.

The DMZ is a biologically and geographically important area where mountains, inland wetlands, fresh water and maritime ecosystems exist. A variety of flora and fauna inhabit the area, including internationally protected and endangered species.  

The DMZ is also a migratory route and a habitat for internationally important aquatic birds and cranes. The area is receiving a lot of attention from the international community for the preservation of its ecological diversity.
