HVG notes that the proposed fence would intersect a 30-40 km section that is part of the European Union’s ecological systemʼs Natura 2000 program, as such the EU has monitoring and legal rights over the territory.

Local environmentalists cited by HVG claim that the fence would seriously hurt local flora and fauna. Reportedly, most of the illegal migrants, daily 100-200, pass through this area on route to Hungary, however, environmentalists say migrants have posed no threat to local wildlife.
