Brad Wallace November 25, 2014 Alberta wolf cull stabilizes caribou numbers, but just buys time: study Brad Wallace November 25, 2014 Buying time is okay, I guess, if you use the time wisely. Will they? I dunno. The study examines the effect of a seven-year wolf cull in the northwestern Alberta range of the Little Smoky caribou herd — roughly 70 animals scratching out a living on land 95 per cent disturbed by forestry and energy development. Seismic lines and cutblocks from that development allow wolves deep into the undisturbed portions of the forest, adding further pressure.
