California Wolverine Coverage

The recent sighting of a wolverine by a hiker in California is generating a tremendous amount of interest – visits to this blog were at an all-time high today, and the media is covering the event thoroughly. Here’s a quick collection of recent articles, for people who are interested:

A second segment on the news features a follow-up interview with a California biologist who is hoping to find more gulos in the California backcountry. It’s difficult not to smirk, just a bit, at the comparison of reclusive wolverines to reclusive Hollywood stars – it’s such a stereotypically Californian analogy. But I secretly kind of like it.

The LATimes ran a short opinion piece celebrating the sighting, and the Modesto Bee featured a short article. Further abroad in the press, the sighting made news amongst gamers (perhaps because of X-Men links) and among Christians (hopefully reflecting a sense of responsibility towards god’s creatures.) Possibly linked to the Christian post (although one hopes not, given history….) the website Inquisitr also ran a story. These are all pretty basic, but the press flurry is intriguing, suggesting a gratifying degree of wildlife interest among Californians. I do wonder about the repeated claims that a lone wandering grey wolf makes Canis lupus “the rarest species in California,” (if there’s a single male of each species, aren’t they equivalently rare?) but….oh well.

For more on California’s wolverines, the California Department of Fish and Game has a page with images taken in 2008 by a camera trap set up for a marten study; this is probably the same wolverine – nicknamed “Buddy” – recently seen by the hiker. The US Department of Fish and Wildlife has a sparse page on the original Californian subspecies of wolverine, Gulo gulo luteus, now believed extinct.  Tom Knudsen has a compilation of information about Buddy, although this was posted back in 2009.

Gulo gulo luteus has also garnered some scientific interest from the Rocky Mountain Research Station, featuring in an article on global wolverine genetics; analysis suggests that wolverines in California show more genetic similarities to wolverines in Mongolia than to wolverines in the Rocky Mountains of the US, although this could be due to convergent evolution rather than descent. Another article out of RMRS details the genetic findings on Buddy, showing that he is not a descendent of the historic Sierra population, and articulates that the wolverine represents the first evidence of gulo connectivity between the Sierras and the Rockies.

We’ll have some more news shortly on wolverines in Wyoming and in Mongolia, so check back tomorrow!

Wolverine Event in Bozeman, and California Sighting

On Tuesday, June 12th, at the Emerson Cultural Center in Bozeman, Montana, Steve Gehman of Wild Things Unlimited will give a presentation on his wildlife research in the Gallatin Range. Gaimen has worked in the Gallatins for many years, tracking wolverine and lynx and conducting citizen science educational and research programs; the presentation will cover several decades worth of wolverine work. The presentation is at 7:30, and is free and open to the public.

A lucky hiker in California caught a wolverine on film in May. The wolverine was near Lake Spaulding, close to the place where a male wolverine was caught on a marten camera-trap back in 2008, and re-sighted every year since. It’s probably the same wolverine, although we can always hope that a female found her way out there and that they are even now conspiring to repopulate the Sierras.

Certainly this is better Californian wolverine news than another recent item, which detailed the confiscation of a stuffed gulo from a bar. The officers went to the bar on a report that two stuffed roosters on the wall were California condors; perhaps the sense of aggravation with people’s wildlife-identification skills led to a determination that their time shouldn’t be entirely wasted. They spotted the wolverine, which had been there for 50 years, and took it, along with a red-tailed hawk. If it’s a Sierra wolverine, it might be a useful addition to the DNA database; the wolverines that originally inhabited California appear to have been genetically distinct from the rest of the Western US population. Sierra wolverines were apparently extirpated in the 1930′s. The wolverine sighted there in 2008 has genetics similar to the Idaho population, suggesting that he is not a descendant of the Sierra population, but a disperser from the Rockies.

The Wolverine Week in Review

A small avalanche of articles on wolverines has appeared over the past two weeks. From an enthusiastic write-up of Doug Chadwick’s Canadian tour promoting The Wolverine Way, to two pleas (here, a piece in New West, and here, in National Parks Traveler) for wider protection of the species in the US, to a synopsis in High Country News of new climate change research that suggests that wolverines are facing harder times ahead, to a recap of the adventures of the lone Sierra male, wolverines are becoming more newsworthy day-by-day. Average daily visits to this blog are about twice what they were six months ago, and attendance at wolverine talks in Colorado, Idaho, and Wyoming has been standing-room-only for the past ten months. All of this indicates an increased interest, which is gratifying to those of us who have long hoped that the wolverine would gain a more prominent place in our collective awareness.

Sometimes, wider attention can be two-edged, however. Over the past few years, as we’ve prepared to induct the wolverine into the ranks of conservation darlings, I’ve had a few moments of panic over the way in which good intentions could go awry. There’s a thin line between reasoned advocacy and blind enthusiasm, and it’s easy for the former to tip over into the latter. The wolverine needs a constituency, but it needs a constituency that advocates for smart things, in a smart way.

Immediately following the listing decision in December,  the environmentalist reaction to the “warranted but precluded” designation was primarily one of disappointment and reproach. I was particularly taken aback by an editorial that lambasted the decision as “political” and called for immediate listing. I’ve struggled to articulate reasons for my reaction to this piece, because I too would have preferred to see the wolverine listed and offered endangered species protections, even while realizing that the ‘warranted but precluded’ status represents a huge step forward. But, after some reflection, after a lesser resurgence of frustration while reading some of last week’s articles, and partially in reaction to some recent discussions about Montana’s trapping season (about which more to come in later posts), I think it comes down to this:

The environmental movement gained its foothold in the midst of the crises of the 1960′s and 1970′s, and its narrative – its essential script – is always of crisis. Environmental advocates are caught in a perpetual reactive cycle that is fundamentally defensive, combative, and angry. And in order to be defensive and combative, one requires, of course, someone against whom to direct one’s anger – an enemy.

In reacting to the listing decision in December, some people chose to cast the federal government in the role of enemy. There have been murmurs within the environmental advocacy community and the growing wolverine fan base, seeking to assign that role to other groups – to snowmobilers, to trappers, to ranchers. It is to the credit of environmental advocates that none of these narratives of threat have blown up and taken off, but the risk is always there. And it is a risk, for two reasons. First, using any of these potent narratives against a specific identity-based group has the potential to evoke an anti-wolverine reaction from politically powerful people. Take a ten-second glance at the state of wolf conservation, and you will understand why this would be a disaster. Second,  re-enacting the ritual battles of cultural identity that characterize environmental disputes in the West distracts us  from the real issues surrounding wolverine conservation, which are climate change and habitat fragmentation.

This, then, is why calls for listing as a conservation solution for wolverines make my stomach flip. Listing has worked fantastically for a number of species, but it’s as if people have come to believe that putting an animal on the list is the equivalent of having conserved it. That’s not the case. The wolverine could be listed, and it would make little difference to its long-term prospects, because we lack the political and social will to tackle those big, looming issues, and the ESA, which doesn’t allow us to regulate for climate change, gives us no grounds to do so.

I’m not saying that we shouldn’t list the wolverine, but that we need to stay focused on substantive as well as symbolic actions. We’ve become so accustomed to fighting for listing as the apotheosis of endangered species conservation that, in some ways, we’re floundering in confusion, and clinging to the comfort of those old successes, as we try to deal with the fact that wolverines – and polar bears, and other species threatened by climate change – call for something above and beyond the predictable strategies that have worked well in the past. We don’t yet know what those solutions will look like, but we know that they will have to be bigger and just as systemic as the problems that necessitate them.

And this brings me back to narratives of combat, crisis, and enemies. If we’re going to tackle these bigger issues, we need alliances, not battle lines. We need to use reasonable federal decisions as a jumping-off point instead of entrenching and employing limited resources to fight the government. We need better data on critical questions about reproduction,  dispersal, and genetic exchange so that we know how to take effective action – which means that we need to fund research and monitoring. We need to guarantee every single wolverine a fighting chance to successfully disperse and reproduce, with as few potential sources of direct mortality as possible. We need instantaneous action on climate change, although – as Synte Peacock’s recent paper on climate modeling in wolverine habitat in the Rockies points out – it may be too late for that already. We need a push for a new conservation narrative, more complex, more sophisticated, and ultimately more successful, that can build alliances for action on those larger issues.

So keep the interest in wolverines high, and keep calling for listing, but let’s make sure that we’re also talking about what we’re going to do beyond that to ensure that the wolverine stays on the ground in the Rockies. There is a crisis, but it’s not a simple crisis with a single solution – it’s worldwide and culturally embedded, and its implications extend far beyond wolverines.

That was something of a rant, and I apologize for any sense of negativity. I deeply appreciate the increasing interest in wolverines and the sincerity behind people’s desire to see it protected. But I hope we can direct energy and resources in the most effective fashion, without getting distracted by protracted legal or media battles unless they are necessary.

To bring things down a notch, I’ll leave off with a series of camera-trap photos from Banff National Park in Canada, which includes some photos of a wolverine gnawing on a moose carcass, and a great action shot of a wolverine in mid-air, chasing a raven. Enjoy.

Strychnine and Consequences

A copy of the Yukon wolf conservation and management plan, written in 1992, fell into my hands today.  On page 3 of the plan, the unintended wider effects of wolf slaughter campaigns in the 20th century are highlighted:

“During the 1920′s, strychnine poisoning of wolves was first allowed in the Yukon….Government poisoning programs started in the 1950′s when up to 154 strychnine poison baits were set out in the southern Yukon each winter. Between 1957 and 1967, a total of about 600 wolves were killed and many other animals were accidentally killed, including more than 150 wolverines.”

Mike Schwartz of the Rocky Mountain Research Station published a paper on wolverine genetics, estimating that the effective population of US Rockies wolverines – that is, the number of wolverines contributing to the gene pool -  is somewhere between 28 and 52 animals. Most of these are in Montana and Idaho. Wyoming holds six or seven known wolverines. Colorado is home to one. We couldn’t lose 150 wolverines, because there are probably barely that many in the US in the first place.

Wolverines are more widespread in northern Canada than they are in the Lower 48, but 150 unintended deaths in the course of a decade still seems substantial. Strychnine and other poisons were widely used in wolf and coyote eradication campaigns in the US, and there is speculation, even beyond the wolverine research community, that the poison baits intended for other predators eliminated wolverines from the US Rockies and the Sierras. The range expansion that we are seeing now, as wolverines make their way to Colorado and California, is, according to this theory, part of a decades-long recolonization process as Canadian and then Montanan wolverines make their way south. In one sense, then, the story of wolverines in the US Rockies in the 21st century is a story of a resilient species making its way home in the wake of astonishingly irresponsible human behavior. And it took little human effort; all we needed to do was stop interfering.

California wolverine

An article about the famous California wolverine, first detected in the Sierras in 2008, came out today in the San Francisco Chronicle. It makes the poor guy sound like a deluded Romeo, reciting the wolverine equivalent of Shakespearean sonnets beneath a balcony that remains stubbornly devoid of a suitable object of affection. As far as anyone knows, this guy is the only wolverine in the state, and his origins remain murky; did he really travel all the way from Idaho on his own, or was he a released captive? His genetics appear to be similar to those of Idaho wolverines of several generations ago, but don’t match the current Idaho profile. Is there an intermediate and undetected wolverine population somewhere between Idaho and California? Or did wolverines make it to California a few decades ago and establish a breeding population that’s maintained that genetic line while the population of origin has shifted?

These questions will remain open for a while. But M56, the wolverine who traveled from northern Wyoming to Colorado last year, traversed sagebrush desert and low hills in order to reach Rocky Mountain National Park, and M57, now living in the Absarokas, was first caught in a bobcat trap outside of Menan, Idaho, either heading into or coming from the sagebrush flats between the Tetons and the Sawtooths. Wolverines are tremendous wanderers, and while high-elevation sagebrush desert may not be suitable long-term habitat, they can certainly move across it between mountain ranges. Males may be the longer-distance travelers, but females are capable of long-distance dispersal as well; a female born in the Tetons in 2004 traveled a straight-line distance of about 187 miles to establish a new home range, but the actual course that led her to the site encompassed a longer and more circuitous route.

This is speculation, but suppose that a female wolverine, in establishing a territory, will select for an unoccupied home range nearest to her place of birth, that allows for adequate food supply for herself and for raising kits, while males will select for the nearest unoccupied home range that allows for adequate food supply and access to a mate. The California wolverine and M57 would, in this hypothetical scenario, indicate that male wolverine home ranges are well occupied through Montana, Wyoming, and Idaho, sending young dispersers farther abroad. Females require slightly smaller territories, so perhaps they haven’t yet saturated the Rockies. But give it a few years, and maybe the California wolverine’s quest for romance won’t be so futile after all. In this context, maybe his efforts to advertise his presence aren’t so pathetic; he’s got enough instinctive knowledge about how his species works to know that one of these days, the girl he’s waiting for will stroll into the mountains just as he did.
