May I point you to a story on the BBC website.
As you may know the Island of Cyprus was partitioned in 1974. A buffer zone was created that cuts the island in half. In the capital Nicosia the buffer is only a few metres apart but in some places the buffer is 7km wide.
This has meant that in places villages have been deserted and the buffer zone has become a haven for wildlife. The residents of the village of Variesia for instance were given 24 hours to move out as the conflict raged in 1974. The animals are seldom disturbed as access in to the buffer becuase you need a UN escort to guide you through the checkpoints and safely past the minefields left over from the battles.
You can read more about it here and here the programme from the excellent BBC World Service here.
