The DMZ is a 150 mile long and 2.5 mile wide strip of land across the Korean Peninsula, more or less following the 38th parallel. With people excluded for 60 years, the land became a haven for wildlife. Behind the barbed wire, many endangered species are thriving, an ironic peaceful outcome from war. The estuary region of the Han and Imjin Rivers and the tideland and riparian vegetation zones are particularly valuable wetlands landscapes for animals. The once ravaged landscape is now green and lush.
