German wolf researcher Werner Freund, 79, a former German paratrooper, established the Wolfspark Werner Freund, in Merzig in the German province of Saarland. Since 1972, the wolf sanctuary has raised more than 70 animals. The wolves, acquired as cubs from zoos or animal parks, were mostly hand-reared. Spread over 25 acres, Wolfspark is currently home to 29 wolves forming six packs from European, Siberian, Canadian, Artic and Mongolian regions. To become part of the pack, Freund must behave as the wolf alpha male to earn the other wolves respect and to be accepted. Photos taken by Lisi Niesner of Reuters.
