European border fences adversely impacting wildlife

The growth of border fences in Central and Eastern Europe in recent years is a "major threat" to wildlife, according to a new study.

Up to 30,000km (18,600 miles) of wire fences and walls have been built, some in response to 2015's refugee crisis.

Researchers say they can divide threatened species such as deer and bear, as well as increase mortality.

The study points out that many of these "temporary" structures may become permanent and have long-term impacts.

The researchers involved in the study believe that many of the fences may have been built in contravention of the World Heritage Convention, the Convention on Biological Diversity or the Habitats Directive of the European Union.

More than anything, the study asks that conservation biologists make their voices heard when governments are planning new constructions; especially as many of the temporary fences may become permanent.
