LANDER -- If there's a war being waged against coyotes in the Cowboy State, a recent troop surge has led to a spike in canine fatalities, according to new federal statistics.
As most observers had predicted, a $6 million, two-year boost in state funding for predator control programs has resulted in an increase in the number of coyotes killed by federal agents who contract with county predator management boards.
During fiscal year 2007, U.S. Department of Agriculture Wildlife Services agents gunned down, snared, trapped and poisoned 10,914 coyotes in Wyoming. It was the highest take yet recorded, and 3,054 more than were killed during the previous fiscal year.
Compared to the preceding seven-year average, federal hunters in fiscal year 2007 killed 61 percent more coyotes.
And the total number of coyotes killed should rise even more when the 2008 figures are tallied, said Rod Krischke, program director for USDA Wildlife Services in Wyoming.
"I think we're going to continue to see the numbers go up a little more," Krischke said. "(Fiscal year) 2007 was a partial year, in terms of the new funding. The (state's Animal Damage Management Board) funded some aerial hunting that didn't start until late spring, and a lot of the new field personnel didn't get started until halfway through the year. So I think when we have a whole year, we'll see an additional increase."
Coyotes have for years been the No. 1 target of USDA Wildlife Services agents in Wyoming, with annual kills in the range of 6,000 to 7,000.
County predator management boards hire the federal agents to take out predators in the hope of protecting livestock. And now with the new infusion of state funding, the boards are also required to spend some of the dollars to enhance local wildlife populations.
"We're hopeful (the increased coyote take) will translate into a reduction in losses of livestock," Krischke said. "But we're also hoping we will see some increases in deer, antelope and bighorn sheep."
Wildlife Services added about 20 people to its statewide force following the funding increase, and now 40 to 45 in-the-field agents are working in Wyoming, Krischke said.
Of the nearly 11,000 coyotes destroyed by the agents in fiscal year 2007, nearly 7,500 were shot from airplanes, according to the USDA statistics released last week.
Another 1,480 were killed by firearms on the ground. The next most common method used was neck snares, with which agents killed 871 coyotes.
Fewer sheep losses
Bryce Reece, executive vice president of the Wyoming Wool Growers Association, said predator management programs that target coyotes are essential to sheep producers.
Reece said he has heard, anecdotally, that following the recent increase in coyote kills, sheep growers are seeing significantly fewer losses to the canines this year, and in some cases the losses are down 50 percent.
Hard numbers for this year, however, won't be available until March 2009, once the results of an annual survey are published, he said.
Last year sheep losses to coyotes dipped to their lowest total in recent history, to 1,300. In 2006 woolgrowers lost 2,100 sheep to coyotes. Back in 2001, about 4,300 sheep were reported to have been killed by the canines. The total number of sheep and lambs on the landscape varies from year to year, but in 2007 there were roughly the same number of total potential lambs in Wyoming as there were in 2001.
"When you're talking to livestock producers, specifically sheep producers, losses are significantly lower, which is going to be tremendously beneficial to us this year," Reece said.
Fewer losses to coyotes will help offset increased losses due to a cold, wet spring, he said.
"A lot of the effort to take out coyotes is focused at or just before lambing," he said. "It's not a long-term thing, we know this -- coyotes move in once there's a void -- but it does remove the ones that are there that could be causing damage (at that critical time)."
Later on in the summer most of the coyote hunting is contracted in response to specific livestock kills, he said.
John Etchepare, co-chairman of the state's Animal Damage Management Board and director of the Wyoming Department of Agriculture, said although no hard numbers are available yet, it's apparent that sheep losses to coyotes has dipped again this year.
"Having been in the sheep business most of my life, anecdotally, we know we've had much better control this year and less loss of sheep," Etchepare said.
The increased coyote take should also benefit some deer, antelope and bighorn sheep populations, he said.
'Constant bloodletting'
Although it might be difficult for some people to stomach, managing coyotes is essential if Wyoming wants to maintain its diversity of wildlife, as well as its sheep industry, Etchepare said.
"Generally, a predator's natural population control, if they don't have a natural enemy, is eating themselves out of a food source," he said. "If we're going to keep a diverse population out there, we're going to have to help manage that, and at some point you have to destroy animal life. The object of this is to control the coyote populations both for livestock and wildlife populations."
But Franz Camenzind, biologist and head of the Jackson Hole Conservation Alliance, resolutely disagrees with that position.
Camenzind researched coyotes for eight years, in which time he discovered that most of the arguments still used to justify exterminating coyotes don't stand up to scientific scrutiny, he said.
The claim, for example, that coyotes will just eat prey until it's all gone is completely off base, he said.
"It's a bogus oversimplification," Camenzind said. "That's kind of hard to accept if you consider how all these species have evolved together. We have national parks where there is no predator control, and the wildlife, including prey, is thriving."
One reason is that coyotes, like wolves, are territorial, he said. Once they get old enough to establish a territory, they set up shop and keep other coyotes out. And the canines also will not overbreed a given geographical area.
Studies have shown, for example, that in unmolested populations of coyotes, there are times when adult coyotes won't breed because the population has become saturated, Camenzind said.
Coyotes tend to be both a scapegoat and a red herring when it comes to struggling wildlife populations, he said. But a well-established biological reality is that food availability, more than anything else, determines the fate of a given antelope, deer or bighorn sheep herd.
"It's habitat, it's habitat, it's habitat," he said.
Killing the coyotes historically has no discernible effect on livestock losses or coyote numbers and has only served to make the coyote population younger, less established and less organized than it would be naturally after establishing territories, Camenzind said.
"These animals are so prolific, they're going to reoccupy habitat. It's going to be a constant bloodletting, a tremendous waste of money, and you're not going to change your overall losses very much," Camenzind said.
Jim Magagna, executive vice president of the Wyoming Stock Growers Association, said coyote control has become more targeted over the years, which has made it more effective in terms of reducing livestock losses. But it has also made it more expensive.
Indiscriminate killing is cheaper, he said, but it's not what is practiced these days.
"The program has always been critical to us, and for a number of years now the goal has not been just to remove the greatest number of animals, but to target the coyotes that are killing livestock," Magagna said.
While sheep producers use other methods of protecting their livestock, including extensive use of guard dogs, there are times when it is essential to contract with Wildlife Services to take out animals that are taking high numbers of sheep, he said.
Lethal predator control is a critical component of a sheep grower's overall program to limit losses to predators, Magagna said, and without it the losses would be too great.
