Yes they are. The wolves imported are 120+ lb Canadian wolves. Much bigger than the 45-65 lb native wolves that were originally present. The wolf packs are wiping out elk, moose and deer. They are attacking domestic livestock. The tree huggers wanted 300 pairs. There at 1500+ and growing.
More like 150+ pounds. However, wolves can go from the 65-85 (to be more accurate) pound range to the full 130-150# range and back again in as little as five generations each way, by as yet not-understood epigenetic adaptation in response to the available food supply. Epigenetics is an amazing field that could explain why many of what at first appear to be "site specific" genetic adaptations that may in fact be phenotypical but heritable traits. This could confound the many "evolutionary significant population" protections we see evoked under the ESA.
