I must admit that whilst the black bear exhibit still disappoints this one is better then I thought with the wooded area in the back more extensive then I had judged from other photos. If it weren't for the 9 or more brown bears in there I'd say it's a world-class exhibit (a rarity for Pairi Daiza).
@KevinB I first thought it to have too little privacy especially with the lodges, but the exhibits extends further back into the forest then I thought. For a few (3-5 maybe?) bears this would be a world-class exhibit as long as the husbandry is fine. For 11 and a group of wolves it's just cramped.
