Uncertain Future for the Gray Wolf

 

Again, An Uncertain Future for the Gray Wolf

By Ken Fischman, Ph.D.

It looks as though Interior Secretary Salazar has struck a deal with Wyoming to end its Endangered Species listing for wolves in that state. According to the New York Times, the arrangement will be similar to that now in force in Idaho and Montana, with a minimum number of 150 wolves and 15 breeding pairs. However, wolves will still be treated as vermin, to be shot on sight year round in 4/5s of the state. Thus, Wyoming has apparently received from the Obama administration most of what it had held out for.

The New York Times August 21, 2012 Editorial, “Uncertain Future for the Gray Wolf, “ (c f.) questioned whether 150 wolves/state would be a viable population for Wyoming, Montana, or Idaho. If you consider that my state, Idaho, contains about 1.3 million people, 20,000 black bears, and over 100,000 elk, the number 150 stands in stark contrast to these populations. No reputable biologist that I know of believes that such a number would be anything but a relict population, genetically threatened by inbreeding, and possibly extinction.

Even Ed Bangs, who was US Fish & Wildlife Wolf Recovery Coordinator, recently admitted that this number of wolves “is not defensible.”
Interestingly enough, the lead article in Science, September 2011, “Trophic Downgrading of Planet Earth”, emphasizes the value of wolves and other top predators in keeping a healthy balance in our ecosystems. It was authored by some of the world’s leading Conservation Biologists. The article is excerpted on the Ancient Pathways web site under the title of  “Trophic Downgrading or Where Have All the Predators Gone,?” and contains a lot of valuable information on the effect of apex predators.

Additionally, Times readers should know that the wolf hunting season in Idaho is now year around, if you count private land, which is about 40% of the state. Any land owner, with a valid wolf tag can shoot wolves on sight. When you consider that the southern third of the state is desert, in which wolves are rarely seen, the territory safe for wolves shrinks considerably more. Also, the number of wolves that can be killed in 8 out of 13 “Wolf Zones” is unlimited.

Obama promised that he would reverse the Bush administration’s politicization of science. This does not appear to be true for wolves. I guess that it is because they do not vote.

Uncertain Future for the Gray Wolf

Wolves in Montana and Idaho lost their endangered species status last year. Interior had concluded that both states had developed management plans that would keep wolf populations at healthy levels.

The delisting has led to the death of hundreds of wolves in sanctioned hunts. But at least Montana and Idaho established limits on hunting seasons and on the number of wolves that can be taken across the entire state. In Wyoming, by contrast, wolves in four-fifths of the state will be essentially treated as vermin that can be killed at any time, and for almost any reason.

Interior says not to worry. Most of Wyoming’s wolves are in the state’s northwest corner, it points out, and can be shot only during a defined hunting season. Further, the state has agreed not to reduce the statewide population below 150 wolves and 15 breeding pairs.

This is a more protective plan than Wyoming’s politicians, ranchers and hunters wanted a year ago. But whether it’s enough to guarantee a sustainable population is far from clear. Interior has promised to review its deals with Montana and Idaho after five years. It must demand the same of Wyoming. The question there is whether, after five years, there will be any wolves left to review.

 

 

Wolf Defender’s View Absent

Wolf Defenders’ View Absent

Rich Landers in Sunday’s Spokesman (Aug. 30), quoted seven people, who were in favor of hunting wolves. It is not that dissenters are non-existent or hard to reach. He could have spoken with Michael Robinson of the Center for Biological Diversity or Carlos Carroll of the Klamath Center for Biological Research. Instead, he relied exclusively on people whose careers and livelihoods depend on agencies whose primary concern is “management” of wildlife. Is it possible that his choice of “experts” was a tad lopsided?
Ed Bangs, U.S. Fish and Wildlife’s wolf coordinator was quoted as saying that the Northern Rockies wolf population was “still growing at an annual rate of up to 20 percent.” The operative words here were “still” and “up to, ” neither of which is accurate.
In fact, Bangs’ own agency shows that wolf population in the Northern Rockies grew by 16.7 percent in 2007, and by only 8.7 percent in 2008. This downward trend shows up also in the statistics for Idaho. Wolf population increased there by 8.8 and 15.6 percent in 2007 and 2008 respectively. 
Wolves could soon reach the biological carrying capacity of their environment without much help from wildlife agencies.

Delisting isn’t based on sound science

Delisting isn’t based on sound science

BY KEN FISCHMAN, Ph.D. AND NANCY GILLIAM, Ph.D. 

Secretary of the Interior Ken Salazar recently ruled that wolves be removed from the Endangered Species Act protected list.

We do not understand how he could have given this complex issue the thorough review it deserved in six weeks. Sadly, we suspect that this is yet another in a long history of political decisions about wolves, and not the scientific one that we had hoped for from this new administration.

The U.S. Fish and Wildlife Service claims that the wolves have made a significant comeback, and that a population of 1,500 wolves in Idaho, Wyoming and Montana will ensure their continued viability. Their number is not a biological reality, but a bureaucratic concept. In reality, there are three distinct populations, each numbering in the hundreds.

Ed Bangs, the wildlife service wolf coordinator, claimed that he had new evidence of genetic connection between distant wolf populations because, in 11 years, a few wolves have wandered between Yellowstone and Central Idaho. What counts biologically is not that a few lone wolves have made long journeys, but whether they have contributed genes to the other populations.

Bridgett vonHoldt from UCLA and her colleagues, in their recent study of the genetics of 500 wolves, has demonstrated that there is no gene flow between these three geographically distinct populations.

Scientists tell us that by 2050, from one third to one half of all species will go extinct due to climate change and habitat loss. Those already on the brink are likely to disappear first.

The low number of wolves living in the Rockies now leaves them vulnerable to inbreeding and environmental challenges.

With populations segregated, predicted habitat changes from warming temperatures are a further threat. We already are seeing habitat loss because of increased acreage burned in forest fires, increased tree mortality caused by disease and increased severe weather patterns.

The principles of conservation biology, the science that deals with extinction and viability of wild animals, also indicate that present numbers of wolves in the Rockies are too low. Michael Soule, the dean of conservation biology, has estimated that biologically viable populations would be “several thousand or larger.”

Our point is not that the wolves should never be delisted, but that doing so at this time would be premature. In a manner of speaking, the wolves are not yet out of the woods.

We do not have to guess at the consequences of premature delisting. In January, when the Bush administration attempted to delist wolves, they were left unprotected for three months until a federal judge issued an injunction. During that time, 132 wolves were killed. At that rate, the entire Northern Rockies wolf population could go extinct in three years.

The big, unanswered questions are what is the minimum biologically viable population for wolves, and how many wolves are necessary to ensure gene flow between the various populations and to avoid the consequences of inbreeding, such as loss of vigor, birth defects and decreased survivability of pups.

President Obama has been promising us a science-based approach to such issues. In fact, the president stated recently during his stem-cell research signing, “É We make scientific decisions based on facts, not ideology.” This is what we would like to happen with respect to wolves.

We were signatories of a letter to Salazar from Northern Rockies groups urging him to convene an expert panel of non-governmental scientists, who would examine the wolf issues.

Wolves have been a matter of bitter contention in the West. Science-based conclusions of a panel of experts may offer a way out of this dilemma, if both sides could be persuaded to accept its conclusions. If the Salazar decision is left to stand, it is certain that these issues will be dragged into court again.
