Wildlife Commission says no more red wolves

Posted Image

The N.C. Wildlife Resources Commission has publicly denounced the red wolf reintroduction in coastal counties, calling for the red wolves to be rounded up — despite being the only wild population of red wolves on the planet.

Last week, the Commission adopted two resolutions: one requesting that the U.S. Fish and Wildlife Service end the red wolf reintroduction, and the second asking the agency to capture and remove all the wolves and their offspring that have ended up on private land.

It is the latest shot fired in an ongoing dispute over the endangered red wolf population along the N.C. coast. Previously, the Wildlife Commission was the target of a court case claiming nighttime hunting of coyotes in red wolf territory was detrimental to the endangered species.

Red wolves look like coyotes, and night hunting increases the risk of red wolves being shot accidentally, according to the court suit. So the Wildlife Commission was forced to rein in coyote hunting in red wolf territory, imposing limits and restrictions on when, where and how coyote hunting could occur.

But the Wildlife Commission continued to assert that shooting nuisance coyotes should trump concerns over red wolves and has now made its opposition to the red wolf reintroduction official.

In the resolution last week, the Commission said that the red wolves were interbreeding with coyotes and encroaching on private lands, and that the red wolf introduction in five coastal counties should end.

The Southern Environmental Law Center, which brought a lawsuit in 2012 opposing the Commission’s red wolf management, disagrees.

“Red wolves have lived — and thrived — on the current mix of private and public lands for 25 years, becoming one of the most successful predator reintroductions in U.S. history,” said Sierra Weaver, senior attorney with SELC. “Asking that the federal government declare ‘extinct’ the 100 red wolves that live in eastern North Carolina is a blatant attempt to remove from the wild one of our country’s most beloved animals.”

For its part, U.S. Fish and Wildlife released a 171-page evaluation of the program in November 2014 and is expected to release a decision on the program’s future early this year.

Meanwhile, the Wildlife Commission is accepting public comment through March 16 on the retooling of coyote hunting rules in red wolf territory.

As one of my favorite animals in the world, I am deeply saddened by this statement. Although the United States government has not released its final decision, I do not think this will end well.

I know that not everyone on this board agrees that the red wolf, Canis rufus, is indeed a species, although I can provide a great deal of literature showing that such an opinion is based on flawed research; however, we still have much to learn about these animals.

Honestly, I feel that it would have been less of a tragedy to have had the red wolf go extinct in the 1980's than to condemn a species that has had success in recovery to go extinct. It flies in the face of all that conservation stands for.

Yes, I signed that petition as well. I am really bummed about this. I have followed this animal since I was a child through all of the controversies and conservation efforts. Hopefully the red wolf will make it through this next attempt at extinction.

Thanks for spreading the word. It is a shame we are giving up on an animal that we know so little about. Whether you think it is a hybrid or not, these animal possess important genes unique to southeastern United States that will be gone most likely forever.

As long-time readers know, I am a bit of a skeptic when it comes to the taxonomic validity of the red wolf. This is particularly true when the only genome-wide analysis of wolves and coyotes in North America revealed that the creatures being conserved as red wolves were actually coyote/wolf hybrids that actually have only slightly more wolf ancestry than a typical Eastern coyote.

That said, there are a lot of individuals who have devoted a lot of time and energy and entire careers on red wolf conservation, but I knew that when that study came out, it would be just a matter of time before the politics of red wolf conservation would come to a head.
After all, North Carolina has just recently begun to have issues with Eastern coyotes, and although most of the coyotes in North Carolina are on the smaller side, it would be wrong to assume that there were no coyotes in North Carolina with wolf ancestry. And it’s possible, considering that coyotes with wolf ancestry have been found as far south as Virginia.

Coyotes are pretty much blamed for everything that goes wrong in conservation biology in the East. If deer hunters don’t bag a huge rack of antlers, then it’s obvious that the coyotes are killing them all. The more nuanced explanation is that coyotes do take quite a few fawns every year, but unless there is a heavy snow (which doesn’t happen in Eastern North Carolina), then it’s very unlikely that the coyotes are killing all the adult deer. Fawn recruitment is an issue, so a lot of game managers, especially in the South, do coyote controls. Coyote controls involve trapping, hunting them with foxhounds, and night hunting.

And it’s this night hunting of coyotes that caused the problem with the red wolf in North Carolina.
Night hunting involves going out at night with an electronic call and an amber light (just to show everyone you’re not spot-lighting deer), and then using those calls, which produce howls and prey in distress sounds, to lure a coyote or two to its demise. Some people are adept howlers, and you can even buy coyote calls that produce different howls and prey in distress calls for that purpose.

Coyotes can be called in the day time, but if they live where there is significant hunting pressure, they tend to stay holed up in the brush until night falls.

Of course, most of the coyote hunters who do this sort of thing got into it to protect deer and other game numbers, and what usually happens is they find the coyote a much more challenging game species than any of the more typical game. Predator hunting becomes an obsession, a deep burning passion. Some of these predator hunters actually want to protect coyotes from excessive hunting, just so they will have more coyotes to hunt.

And this is where red wolf recovery went south.

In the five counties where red wolves roam, there has been a long legal battle over whether coyotes can be hunted in red wolf range. In May 2014, a court-ordered injunction banned coyote hunting in those five counties, but by November, the N.C. Wildlife Resources Commission created a framework that would allow some limited coyote hunting in the area. Also, if one is legally hunting coyotes, one can kill a red wolf if it is taken by accident. I should note that red wolves look a lot like Eastern coyotes. They are the same color, but they are usually somewhat larger than the coyotes typically found in North Carolina. However, I can tell you that if red wolves were released here in West Virginia, you would never be able to keep them straight. We actually do have coyotes that approach red wolf size, which kind of makes sense. After all, the coyotes of the Northeast and the Mid-Atlantic are essentially the same thing as red wolves– coyotes with some wolf ancestry.

You would think that this rule alone would be enough to get red wolf conservationists screaming, but what came next is something akin to a neutron bomb going off in the red wolf community.

Last week, the North Carolina Wildlife Resources commission issued two resolutions to the US Fish and Wildlife Service. The first resolution declared that because the extant red wolves in North Carolina were so heavily derived from coyote stock that there were no more pure red wolves left and that the species was extinct in the wild as of 1980– which, means that the red wolf recovery program would end under the Endangered Species Act.
Once a species is declared extinct, it gets removed from the Endangered Species List, and all recovery efforts are ended.

The second resolution calls for a removal of red wolves from private property.

In the 90’s and the first decade of this century, the red wolf recovery program in North Carolina was celebrated as a successful wolf reintroduction in the East. These wolves lived in area where most confined livestock and poultry operations and crops comprised the main agricultural concerns. Very few opportunities existed for red wolves to cause problems with people.

But now that coyote hunting is gaining in popularity in the state, the red wolves finally hit snag. Of course, the Fish and Wildlife Service could only maintain the supposed purity of the red wolves running loose in North Carolina though an intense trapping program. The population of canids called red wolves today derive from only 14 individuals, and as we know that most wild canids have a strong inbreeding avoidance instinct, red wolves will readily cross with coyotes. After all, red wolves are mostly coyote in ancestry, and those 14 were all derived from a population of coyotes and wolves that were running together in Louisiana and East Texas. In Peter Steinhart’s The Company of Wolves, the author recounts a government trapper in Louisiana who kept encountering litters of coyotes, where one pup would mature at 75 pounds, while another would top out at 25. This strongly suggests that the red wolf that exists now was a hybrid. There were some rather primitive genetic tests done on these wolves, but these were quite unlike the vonHoldt paper.

What likely happened was that as wolves in Texas and Louisiana became rarer, they began to mate with coyotes. Because this wolf held on longer than in other parts of the South, there were more hybrids with wolf-like features that were then declared a species. There was some dodgy paleontology work that connected these wolves with primitive wolf-like canids from North America. They found some unique biochemical and molecular evidence in the 14 wolves, and based on the dodgy paleontology, the primitive biochemical and molecular evidence, and the phenotype, they declared these animals to be a species.

I haven’t seen anything that any researcher has produced that falsifies the vonHoldt paper, which is the most extensive analysis of wolf and coyote genomes performed to date.

Now, I am a big supporter of the Endangered Species Act. I am also a supporter of wolf recovery programs, but I’ve come to think that this particular program is quite problematic.

The taxonomic value of the creatures we are currently calling red wolves is dubious at best. I’m open to some good evidence that contradicts the genome-wide study I linked to earlier, but I haven’t seen it. All I’ve seen is a critique of that study, which basically says you can’t use SNP’s to determine evolutionary relationships, but SNP’s look at much more of the genome than microsatellite clustering and mitochondrial DNA do– which all that the red wolf researchers have.

Also the big critique on the red wolves are hybrids study I’ve seen is they didn’t sample enough red wolves. The problem with that argument is when a population derives from only 14 individuals, you really don’t need a huge sample to get an idea of what they are.

This is one of those cases where I think the best science is on the side of delisting the red wolf.

And let’s worry about Mexican wolves.

Or maybe the diamond darter, a tiny fish that is now only found in the Elk River drainage of West Virginia.

But that’s just a little fish, living in a state where economic interests that generally oppose clean water have long held sway over the political process.

It’s not some ancient American wolf, which at one time was declared the root-stock of all wolves and coyotes.

Wolves are great symbols of conservation. If left alone, they do recolonize their former range and often thrive. They are also closely related to domestic dogs. Indeed, dogs are derived from some Old World form of Canis lupus, and to the popular imagination, killing a wolf is like killing beloved pet dog. The wolf became sort of a “Fido as a Noble Savage,” which in itself is a pretty bad place for animal to be.

So because this symbolism that having hard discussions about wolves is difficult.

Protecting endangered species is more than raising hell whenever charismatic species might be threatened. It about preserving ecosystems and habitat, as well as all the unsexy little creatures, ones that will only gets nerds like me excited.

I would hate for this red wolf fiasco to set a precedent that state wildlife agencies can just complain to the US Fish and Wildlife Service whenever a particular endangered species is causing them problems. The Western states have even more endangered species that are conflicting with state interests. For example, it was recently determined that the sage grouse of southeastern Utah and southwestern Colorado are a unique species, and what’s more, it’s actually an endangered species. In November of 2014, it was decided that this species of grouse, called the Gunnison grouse requires Endangered Species Act protections. The state of Colorado just sued Fish and Wildlife Service over the listing. Now, it’s unlikely that these grouse are going to be delisted because Colorado complained about them, but depending upon how the courts interpret the law, it could get interesting.

Red wolves are just a bad case all around.

The lesson to conservationists ought to be that if you want to save a species, you better make sure that there are no huge, gaping questions about its taxonomic status.

I think the sad story here is that we’ve lost the Southern wolf, replacing it with wolves with a high amount of coyote ancestry, does not change this fact.

The Southern wolf is mentioned in the literature throughout region, and it was almost universally described as melanistic.

Here is photo taken by an early camera trap in Louisiana by Tappan Gregory in 1935. It shows a black wolf with a larger head, broader muzzle, and smaller ears than what one finds in the modern “red wolf.” (The current “red wolf” subspecies is call Canis rufus gregoryi, after Tappan Gregory.)

That wolf is gone. Perhaps it lives on the wolf genes of the modern hybrid red wolf, just as the Northeastern timber wolf (Canis lupus lycaon) lives on the “coywolves” the Mid-Atlantic and the Northeast.

The thing about wolves, though, is they are coming back. Bit by bit. Some wolves have incorporated coyote blood, as is the case with the Algonquin Park wolves, and this hybridization even occurred before Western man arrived in this continent. The vonHoldt paper on wolf and coyote genomes showed that Great Lakes wolves hybridized with coyotes at some point 600-900 years ago.

That means that wolves and coyotes, like modern humans and Neanderthals and Denisovans, exchanged genes with each other. Our popular understanding of evolution is that a species origination is one monophyletic population becoming genetically distinct and then losing chemical interfertility with the ancestral population and the sister taxa. However, evolution also has sister taxa exchanging genes a lot more often than we generally assumed. Wolf and coyote hybridization in North America has actually been underestimated as a driving force for the evolution for both species. We know that wolf genes have given Eastern coyotes an advantage when it comes to hunting deer and has likely enhanced their spread into the white-tail woods.

When wolves came into this continent from Eurasia, they came into land full of coyotes. It is possible that they exchanged genes then, but there is no record for it. Or maybe those early hybrid populations became extinct.

What we do know that is that hybridization occurred without the influence of Western Civilization and its attendant philosophy of wolf persecution, and in the case of some wolf populations, coyote genes could be a source of genetic rescue.

So the wolf that will come back won’t be exactly like the one that was extirpated. It will have genes from coyotes and probably domestic dogs.

And we should just accept it. After all, no one says that we should kill all the black wolves, even though that black coloration came from crossing with domestic dogs.

The wolf that comes back will be in a world where there aren’t as many elk or moose to hunt, but there will be plenty of white-tailed deer and raccoons. This wolf will have to be adapted to hunting this quarry, and it will have to be as wary as a the most paranoid of coyotes in order to survive in this new New World.

This is the approach that should have been used to restore wolves to the Lower 48. It avoids all the crazy debates about taxonomy, and it recognizes that ecosystems have been changed profoundly since 1492.

So if North Carolina succeeds in ending the red wolf program, maybe it will be a chance to go forward towards a twenty-first century wolf conservation ethic.

That’s certainly what would be best for the wolves, for wolves have to fit into our world now. They can do it, but we can’t get them there if we hold onto old ways of thinking.

I knew in the first few lines who wrote that piece. This guy got all excited by the red wolf is a hybrid paper, because that was his personal hunch, that he has since considered every scientist and specialist since then who disapproves of the paper as being biased. He fails to see the hypocrisy of his own position. The vast majority of canid scientists (why are we worried about a lay blogger anyway??) consider the red wolf worthy of conservation. Indeed the majority of these scientists also consider the red wolf to be a unique species to North America.

At a minimum, we should at least let a study come out that supports or contradicts the red wolf hybrid study (vanHoldt et al 2011) using similar methods. Such an approach is simply good science.

People think genetic analyses are fool proof, yet they fail to realize how complex this approach to phylogenetics is. There are often multiple trees produced by genetic analysis, with the tree with the lowest "error" being chosen as most likely. This sounds wonderfully simple but the fact of the matter is that many of these trees don't always make sense with similar trees using similar techniques in other studies. We are still unsure about the phylogenetics of Panthera. These are popular animals, and there is certainly no shortage of attempts to elucidate their evolutionary relationships over the past two decades using genetic analyses.

People seem all too hasty to put the final nail in the coffin of these animals.

Calling a species extinct when it clearly still exists would be the greatest tragedy to hit conservation biology since its conception.

This is nothing personal against you MightyKharza. I know you are simply trying to provide a different perspective, and I appreciate that. All sides of the story should be told.

/End rant.



EDIT: For the most up to date summary of North American Canis, I refer you to: Chambers et al. 2012. An account of the taxonomy of North American wolves from morphological and genetic analyses.

Here is the paper that found red wolves to be hybrids: vonHoldt et al. 2011. A genome-wide perspective on the evolutionary history of enigmatic wolf-like canids


EDIT 2: Again, I hope I do not appear to be overzealous, and I certainly don't want to be closed off to other studies/opinions. As I said, I have followed this story, watching it unfold, since I was in secondary school. It is an issue near and dear to my heart.

Now on the species debate. Let's say the species is a hybrid. This one is natural unlike let's say the sika deer x red deer and white-headed duck x ruddy duck. Is it worth preserving a hybrid species? Yes or no? Why?

If the red wolf is indeed a natural hybrid, it is worth preserving the unique genes that it possess. In other words, the goal would be to preserve the evolutionary process that was taking place prior to disruption by Europeans.

As I have said in previous posts,, hybridization lacks a negative stigma in botany. It is seen as a perfectly valid method of speciation.

Compare with modern red wolves. Fairly similar.
As to interbreeding with coyotes, it's probably not too common. The wolves know the difference.
From Reddhole:

Red-Wolf Coyote Interactions

Today's wolf focus (11301M) was collared late last winter while still a yearling and living with the pack in his natal home-range just south of Columbia, NC. The subsequent collar downloads provided us with accurate home range data from where he was born and much more. Because most young wolves disperse from the pack between 12-24 months of age, we were able to follow 11301M as he left his natal home range this spring and began his travels from place to place. We could see his path as he seemed to go from wolf pack to wolf pack looking for a place to live. We could see how he skirted the core areas of the adjacent packs in order to stay out of trouble with other wolves (a smart thing for a young single wolf). We even tracked him as he moved completely around Lake Phelps before stopping on Pocosin Lakes NWR where a female wolf (11358F-also born in 2004) had just paired with a sterilized, radio-collared wolf/coyote hybrid.

The most recent download showed how 11301M not only displaced the hybrid out of the pack's area, but likely killed him. After retrieving the carcass, our theory seemed to be correct. As I fly over Pocosin Lakes today, I can see that 11301M has paired with 11358F. Together, they will now form the new Pocosin Lakes pack. These types of wolf/non-wolf interactions where the non-wolves are displaced, are some of the observations the new GPS collars will allow us to record.

Red wolves are confined to a very small area, with no certain place for them to expand. Wolves, and all Canis for that matter, are wide ranging. Restricting them to such small areas and calling them recovered is not conservation. All recovery programs are doomed to fail that have rules in place to inhibit normal population growth and expansion.

The edge of their range may always be a place of hybridization, but when their range is so small, it gives the appearance of nothing more than a hybrid swarm and failed recovery.

The program needs to be fixed, not abandoned.

The problem with hybrids is that many of them are a big source of genetic pollution for similar, nearby species, so some conservationists don't like them very much.

I'm not sure if this is the case of the red wolf, but I do believe they are more likely to hybridize with coyotes than "pure" wolves.

I know about genetic pollution, but I thought this was only a concern when it happens with non-native species such as the examples I made. Or with subspecies in zoos and when reintroducing species. Not say, naturally occurring hooded crow x carrion crow.

Because I haven't heard of concerns about hooded crow x carrion crow. And in Europe the interbreeding with wolf subspecies is recommended.

Hybrid > inbreeding
Red wolves should be allowed to naturally hybridize to coyotes to avoid inbreeding.
