BAD BERLEBURG, GERMANY - MAY 05: Gustav Prince of Sayn-Wittgenstein-Berleburg, one of the initiator of the bison-project, pictured on May 5, 2014 at Bad Berleburg, Germany. The herd is a project of Wisent Welt Wittgenstein, a government-funded initiative which last year released the herd in an effort to restock the bison in the wild. European bison were once plentiful across Europe and Russia, though their numbers were decimated to near extinction by hunting and habitat encroachment. (Photo by Thomas Lohnes/Getty Images)
