Federal U.S. Geological Survey wolf biologist and trapper Dave Mech, pointing his finger at rising wolf numbers as responsible in his field-study area for the decline in moose suggests that the Minnesota Department of Natural Resources (DNR) “could allow hunters to kill more wolves in the moose range until the population recovers”. (Star Tribune Nov 2, 2014, p.C18). Ironically, on this same page, reporter Dennis Anderson in his article “Gone From Sight” presents a debate on the dramatic decline in the state’s whitelail deer herd, with finger-pointing at DNR mismanagement and over-harvesting. Earlier data indicate that when the wolf was protected under the Endangered Species Act the whitetail deer population flourished. Wolves keep deer on the move, preventing overgrazing/browsing and tree damage. As though to bolster Mech’s questionable opinion, Anderson subsequently published a long interview with Mech ( Star Tribune Nov 16, 2014, pC20) who plays cautious scientist when it comes to climate change and associated debilitating tick infestations being significant factors in the decline of moose especially in northeastern Minnesota. He repeatedly states that while these factors may be “true” or “possible”, “we don’t have evidence of it”, while insisting that wolves are the main cause, along with consecutive bad winters.
Bad winters and too many hunters diminish deer numbers which means more wolves prey on livestock, some 200 wolves being killed for doing so in 2014 by state and federal officials. Regardless, the MN DNR set a wolf quota of 250 animals for the 2014-5 season, some 15,000 people applying for 3,800 licenses to shoot, snare or trap them. DNR wolf manager Dan Stark states that “The hunt isn’t having a significant influence on wolf numbers”, insisting that the de-listing of the wolf as an endangered species was not intended to reduce wolf numbers (because there were too many, which many people argued), but to “have a sustainable hunting and trapping season”. ( Star Tribune Nov.16.2014 p C20)
There are many factors involved in the demise of Minnesota’s moose, especially wetland encroachment and drainage for agriculture; parasites, disease and massive winter tick infestations that lead to anemia, weakness, proneness to predation and failure to thrive and reproduce, climate change notwithstanding. While several moose have been killed accidentally by DNR researchers applying radio-collars and some Native American Indian tribes claim their right to kill their entitled annual quota of moose regardless of their threatened status, all involved parties, regardless of their best intentions, surely need to step back. Current wildlife management policies and practices need to be examined. Is the goal to maximize human interests in terms of “sustainable harvesting” of trophy and consumable species of commercial value, or to maximize species diversity for ecosystem health and sustainability? Surely the demands and influence of the human species on other species and their habitats must be constrained for the greater good rather than directed by some economic or social, recreational good. We cannot control the weather but to some degree we can control ourselves. Reducing the wolf kill quota to zero for 2015-6 may be a good start for the DNR in recognizing that wolves are biologically the better wildlife managers than they.
