Mexican wolf program: Bound to fail, but not because of ranchers

These are not words that pro-wolf people like to hear, but they need to be said: The Mexican wolf program will fail. It was fated to fail right from the start.

Contrary to what some preach, it's not because of ranchers, or obstructionist local governments.

No, the program has been doomed from day one because of a false premise of biology, and a false promise to the public.

Background

In 2014 over 100 Mexican wolves were counted in the wild in New Mexico and Arizona. In 2015 there were fewer counted, but that doesn't mean that there were fewer wolves. By the nature of the methodology the count does not include all wolves. The count is performed by fly-over. A spotter plane finds a wolf pack, and the wolves are then counted from a helicopter. Obviously there is no way to get an accurate count with this method. Wolves don't stand still to be counted, they run every which way. Some may hide and not be counted at all. Some may be counted multiple times. Some wolves might simply never be spotted by the plane, especially those that are outside the official Mexican wolf area (like the ones that are in my area).

Whatever the count, Fish and Wildlife Service biologists say the number of wolves is too few to ensure a diverse gene pool for the species.  Environmental groups, like Defenders of Wildlife, say the release of captive-bred wolves is imperative to the genetic health of the wild Mexican gray wolf populations.

I say that no number of Mexican wolves will ever ensure a diverse gene pool.

You can't make something out of nothing.

Every single known Mexican wolf in the US, both in the wild and in captivity, is a descendant of a very limited gene pool of captive wolves. I do not know what the genetic spread of the Mexican wolf might be, because that seems to be a big secret that the public is never allowed in on even though we foot the bill through our tax dollars. But I do know that you can't create something out of nothing. You can't create a diverse gene pool for a species from a limited founding population.  

This is well known science. It's true for animals in the wild, so it's got to be true for Mexican wolves. Take the cheetah, for example. About 12,000 years ago, a mass extinction event caused an extreme reduction of the cheetah's genetic diversity. Today the cheetah suffers from what is called the "founder effect". This is when a new population is started by a few members of the original population. Such a small population size results in reduced genetic variation from the original population and a non-random sample of the genes in the original population.

Genetic diversity serves as a way for populations to adapt to changing environments. Lack of genetic diversity can, all by itself, lead to extinction for that population. All it would take is one disease that the cheetah population is genetically unable to resist. Lack of genetic diversity means that if some cheetahs can't handle the changes in their environment brought about by climate change -- something that's a fact of life right this very moment -- then the likelihood is that none of them could handle it.  As it happens, it appears that climate change has already adversely affected the ability of wild cheetahs to reproduce and to hunt.

Why would Mexican wolves be more resilient than cheetahs?

If 12,000 years isn't enough for cheetahs to recover genetic variation why in the world would any scientist pretend that 40 years of human selective breeding will build genetic variation in the Mexican wolf? Build it from what? You start with x amount of genetic variation and that's what you have to work with. There isn't going to ever be any more.

"From seven animals you have a reduced genetic diversity to begin with... we won’t increase genetic diversity unless we magically find a new animal, which we won’t,” Sherry Barrett, head of the U.S. Fish and Wildlife’s Mexican gray wolf Recovery Program, recently said.

There are over 300 Mexican wolves in captivity, some in zoos, some running semi-free in preserves. All of them live in controlled conditions and receive regular veterinary care.  If there was any point to raising more Mexican wolves, it could be readily done. But what's the point?  All the captive wolves come from the same founding population. They don't have different genes. Breeding more of them won't save the species because there will never be more genetic diversity than there is right now.

If the head of the U.S. Fish and Wildlife’s Mexican gray wolf Recovery Program knows that the program is not going to create genetic diversity, what is the program for?  To raise more animals for zoos? Mexican wolves are at tremendous risk in the wild and it would take very little to wipe them out. Putting more wolves in the wild, as Defenders of Wildlife and others want, won't change anything.

Albert Einstein may or may not have said “The definition of insanity is doing the same thing over and over again, but expecting different results”.  It seems true no matter who said it.  So I have to ask:  Why do we continue to pour money into the Mexican wolf program that, purely on a scientific basis, is doomed to fail?  Isn't that kind of insane?

Mexican wolf - spinning the results for another year

A few days ago US Fish & Wildlife Service (FWS) issued a news release about the status of Mexican wolves after their annual wolf survey.  The count is down and the media is, of course making a lot of noise about a drop in wolf numbers. 

Interesting about how played down it was that two female wolves were killed during the survey by the people doing it.  And as for the remaining supposed drop in numbers? Well, FWS and the media don't want to mention that that the numbers given are actually a minimum population estimate for 2015, not an actual count. And it seems nobody wants to provide a maximum population estimate, because then one might begin to wonder why the wolf needs so much counting and protecting and all.

You can't get the flat truth from government news releases; you get spin.  And of course we know the media doesn't actually care to report "truth" or "fact" since it doesn't build readership. So you have to go to the official reports, not that US FWS makes it easy to find them.  

The news releases don't describe to the public what actually happens once a year when they're counting wolves, or what the numbers they give out actually mean. 

If you read the official reports you discover that the best that the agency can do is to count the number of wolves with working collars and the ones they were able to trap without working collars - and then to guess at how many more wolves there might be out there (a minimum guess, of course).   

Actual counting is accomplished mostly by herding wolves from the air and counting them as they run. The news releases and media don't tell the public that they also dart the wolves from helicopters so they can get collars on them or replace batteries, or give them physicals or vaccinate them.  

And they trap wolves, too.  


The news releases don't mention how a trap might happen to break a wolf's bones. Or that the agency have turned three-legged wolves back out into the wild.  The news releases don't tell you about whether the three-legged wolves survive.  

Or that sometimes the stress of being run, trapped, darted, and handled by humans happens to kill a wolf. Or two.  

Please explain to me how it could possibly not be a risk for any wild animal, much less wolves, to be treated this way once a year, every single year of their lives.  Please explain to me how often this can be done to wild animals before they are no longer wild.

Please explain to me why people are outraged that "ranchers are bad for Mexican wolves" when there's no study that's been done on the effects of Mexican wolf management itself on the wolves?  

This is not science.  This is not a program being operated for the benefit of wolves or the environment. I can't imagine how any animal lover could support the Mexican wolf program.  It's not a program, it's simply animal abuse.

I never thought I'd ever say this, but where is PETA when you need them?

Catron County Commission Demands Wolf Incident Investigation

FOR IMMEDIATE RELEASE        

RESERVE, NM.  “The wolf issue is one of the biggest problems the county has faced,” said Catron County Commission Chairman Hugh B. McKeen to Tod Stevenson, Director of New Mexico Department of Game & Fish at a regularly scheduled public meeting on Wednesday, April 6, 2011.  With Mr. Stevenson were RJ Kirkpatrick, Assistant Director NM Game & Fish; Jim McClintic, Chairman New Mexico State Game Commission; and Dick Salopek, New Mexico State Game Commission.  An audience of nearly 100 people attended the meeting.

In late January a formal complaint was filed by the county with NM Governor Martinez regarding a wolf depredation investigation that occurred on January 18, 2011.  Catron County contends that NM Game & Fish wolf biologists Ellen Heilhecke and Mischa Larisch allegedly sought to influence or change the official investigation findings of Sterling Simpson and Armando Orona of US Wildlife Services during an on-site investigation as to the cause of death of a cow. 

“Influencing or attempting to influence the findings of another agency’s official investigation brings up a lot of problems,” said Catron County’s Wolf Incident Investigator, Jess Carey.  “The credibility of the game department wolf biologist is now lost.”  Simpson and Orona did confirm that the cow was killed by wolves, with Carey concurring.

“Other findings of confirmed wolf kill have been changed to probable in the past,” Carey said.  “How can you change documented evidence?”

Stevenson confirmed that Larisch did call and relay a message from Heilhecke to the Wildlife Services personnel while the investigation was in progress, but denied that any impropriety occurred.

“My staff said they did not say that Wildlife Services should modify the finding from confirmed to probable,” Stevenson said.  “My folks called and said there were feral dogs in the area to take into consideration.”

“There were no feral dogs on this ranch,” Carey said.  “Last year, several miles away, a neighbor was letting his house dogs run loose, but that problem was resolved.  Mr. Simpson concurred:  There are no feral dogs out there”. 

At the conclusion of the meeting, Catron County Attorney Ron Shortes stated that he agreed with the Commissioners’ and Carey’s call for an independent, third party investigation of the incident.

“I think you have a conflict of interest when you say you have an obligation to facilitate this Mexican wolf recovery program vs. your constitutional obligation to the people of NM to protect wildlife,” Shortes said.

“While an independent investigation is needed, my ultimate feeling is that you have a bunch of good people with the New Mexico Game Commission and NM Game & Fish trying to do their best, but I’m wondering if they’re trying to do too much,” Shortes said.  “They’re assisting the recovery program on one hand, trying to protect wildlife on the other – is there any possibility of trust while that’s going on?”

After a show of hands to see how people in the audience felt, the Catron County Commissioners voted unanimously to go ahead with their request of Governor Martinez for a full, independent investigation of the incident.  Director Stevenson volunteered to provide a synopsis of the progress of the investigation by April 15, 2011. 

“Catron County has taken a no-wolf stand,” McKeen said.  “I’m requesting that you take a no-wolf stance, too.  It’ll do us all good – we’re not only concerned about livestock but wildlife, too.”
