“…The DMZ covers a total of 907 km 2 , and has remained a virtually "noman's land" for the last 65 years and, thus, a sanctuary for biodiversity (Kim, 1997(Kim, , 2013. Moreover, along the southern boundary of the DMZ, the Civilian Controlled Zone (CCZ) was set for military purposes, with a width ranging from 5 to 20 km; the CCZ, with 1369 km 2 (Kim, 2013), has become an area where human activities are strictly limited (only some farming is allowed; Kim et al, 2011). Altogether, both areas account for almost 2300 km 2 of relatively pristine lands that are acting as a de facto nature reserve.…”
