Hungary's controversial fence - the cost to wildlife.

The decision to erect wire fences on its borders with Croatia and Serbia in order to stop the influx of refugees and migrants into Hungary has been extremely controversial, and while the Hungarian government's policy of barring entry to those arriving from Syria, Iraq and Afghanistan may have been successful, a Facebook post by famous Croatian photographers, Romulic and Stojcic, on October 19, 2015, show another side of the story - the terrible effect the fence is having on the wildlife of the region.

The above photograph by Janos Horvat was taken on the Hungarian border, close to the towns of Beli Manastira (Croatia) and Mohacs (Hungary), just 500 metres from the border crossing of Udvar.

As Romulic and Stojcic explain in their Facebook post on the subject, the trees in the border in the video below are on the border between Croatia and Hungary, and until recently, herds of deer used to migrate freely across the border, sometimes in their thousands.

No longer. The erection of the fence has added further complications to the migrant route to Germany, but is the cost to wildlife set to be a longer term consequence for the region?
