While on a recent trip at the Bavarian Forest National Park (BFNP) in southeastern Germany, I visited the Haus zur Wildnis (House of Wilderness), a small zoo situated directly in the forest that keeps lynxes, grey wolves, Przewalski horses and Auroch-type cattle.
I could spot five grey wolves (Canis lupus) out of 12. The animals are kept in a small 4,5 ha enclosure that appears larger only because the fence is concealed by a natural bush cover. To put things into perspective, in the wild wolf territories can reach hundreds of square kilometers, like in southern and central Europe where typical ranges are comprised between 82 and 243 sq km. Size varies substantially depending on prey density, vegetation type and other factors.
