The DMZ owes its varied biodiversity to its geography which crosses mountains, prairies, swamps, lakes and tidal marshes. Environmentalists hope that by the time reunification occurs, the former DMZ will be conserved as a wildlife refuge, with a well-developed set of objective and management plans vetted and in place. In 2005, CNN founder and media mogul, Ted Turner, on a visit to North Korea, said that he would financially support any plans to turn the DMZ into a peace park and a UN-protected World Heritage Site.
