Proposed Removal of Gray Wolves’ Endangered Status a Case Study in the Politicization of Science

by James William Gibson

The US Fish and Wildlife Service’s recent announcement that it is beginning the process for removing gray wolves across the country from the protection of the Endangered Species Act surprised no one. The Fish and Wildlife Service’s mid-1990s reintroduction of gray wolves — a species virtually extirpated in the nineteenth and twentieth centuries — into Yellowstone National Park and central Idaho marked a triumph for conservationists and ranks as one of the most striking fulfillments of the Endangered Species Act. But as I have reported here and here, the wolves quickly met enemies...
The FWS’s proposed delisting of gray wolves across the country is simply the continuation of the agency’s long retreat in the face of wolf hater intimidation. Still, it’s important to understand how the FWS legitimizes its abandonment of wolves. A close examination of the FWS’ proposed rule change is a case study in the politicization of science. The FWS report excels at cherry picking, choosing certain scientific studies while rejecting others. It’s also an excellent example of bureaucratic hand-waving, simply dismissing long established facts whenever they become inconvenient. The final result is like a weird game of scientific Twister: The FWS bends itself into all sorts of contortions to conform to a political agenda.
Repetitive and often inconsistent, the 215-page proposed rule makes two stunning claims.  First, the FWS says “new information on C. lupus taxonomy” published in 2012 reveals that the gray wolves (C. lupus) do not constitute “either an entire species nor an entire single subspecies.” Simply put, C. lupus “does not represent a valid species under the [Endangered Species] Act”  — and thus cannot be listed as endangered. Having decided that gray wolves are not a valid species, the FWS then deconstructs the category, saying all wolves formerly called gray actually belong to one of three subspecies of wolves and one new species.   
The FWS then makes the rather bizarre claims that the agency wasn’t really serious when, back in 1978, it listed gray wolves as endangered across an historical range covering most of the lower 48 states (except Minnesota, where it was listed as “threatened”). Rather, the agency now claims, the 1978 reclassification “was undertaken to ‘most conveniently’ handle a listing that needed to be revised because of changes in our understanding of gray wolf taxonomy, and in recognition of the fact that individual wolves sometimes cross subspecies [geographic] boundaries.” Now, the FWS argues, “this generalized approach to the listing … was misread by some publics as an expression of a larger wolf recovery not required by the Act and never intended by the Service.” Evidently the FWS never really had wolf recovery as a goal.
In place of this unintended “larger wolf recovery,” the FWS in its newly proposed rule lists three subspecies and alludes to one new wolf species, each with a limited population size and a clearly limited range.  Conceptually, deconstructing the gray wolf category constitutes a containment strategy, a way to scientifically legitimize small, remnant wolf populations restricted to finite ranges; wide-ranging wolf dispersal is eliminated as a possibility. This containment appeases politicians, government administrators, businesses, ranchers  and hunters — all those who fear disruption from  wolf recovery.
What the FWS used to call the gray wolves living in Northern Rocky Mountains, — a “Distinct Population Segment” in biology nomenclature —  is now conceptualized as the wolf subspecies,  C. l. occidentalis.  Wolves classified as occidentalis , according to the FWS, “currently occupy nearly the entire historical range of the species.” In what I can only call an act of scientific chutzpah, the FWS therefore argues that these wolves are considered fully recovered. And since they are fully recovered and are occupying their historical range, then any occidentalis  that disperse to Washington, Oregon or Colorado are classified as a non-native species. Although individual states might choose to list them as endangered—Washington and Oregon have done this — they will not qualify as a federally protected Distinct Population Segment of gray wolves. That’s because the FWS no longer considers gray wolves to be a valid species. Nice circular logic, that.
And here's what he has to say about Mexican wolves:
There is one bright spot in this otherwise gloomy picture. One subspecies of the supposedly no longer valid Canis lupis  will receive protection under the proposed rule: the Mexican wolf, or C. l. baileyi.  A tiny remnant population of Mexican wolves — abount 75 — live in eastern Arizona and western New Mexico. Another 250 live in captivity in the US and Mexico awaiting reintroduction to the wild. The FWS wants to maintain the endangered listing for C. l. baileyi, saying it is “in danger of extinction throughout all of its range due to small population size, illegal killing, inbreeding, and the cumulative effect of all threats.” The FWS says its interim goal is to support 100 wolves, at first glance a significant improvement.
But it remains uncertain how — or whether — the FWS proposes to bolster the population of Mexican wolves. In 2011 a subdivision of the FWS tasked with developing a plan for Mexican wolf recovery concluded that the agency would need needed three distinct recovery areas connected by corridors across parts of Arizona, New Mexico, Colorado, Utah, and Texas, with each area to become home for 200 to 350 wolves. The head of the Mexican Wolf Recovery Team immediately came under massive political pressure from state wildlife agencies and the governor of Utah, who made a range of political and economic arguments to curtail the scientists’ recovery plan. Unsurprisingly, the June 7 proposed rule says nothing about what full recovery would entail...
