Deer-killing disease

Northern Plains hit hard by deer-killing disease


BILLINGS, Mont. (AP) — White-tailed deer populations in parts of eastern Montana and elsewhere in the Northern Plains could take years to recover from a devastating disease that killed thousands of the animals in recent months, wildlife officials and hunting outfitters said.

In northeast Montana, officials said 90 percent or more of whitetail have been killed along a 100-mile stretch of the Milk River from Malta to east of Glasgow. Whitetail deaths also have been reported along the Missouri and Yellowstone rivers in western North Dakota and eastern Montana and scattered sites in Wyoming, South Dakota and eastern Kansas.

The deaths are being attributed to an outbreak of epizootic hemorrhagic disease, or EHD. Transmitted by biting midges, EHD causes internal bleeding that can kill infected animals within just a few days.

"I've been here 21 years and it was worse than any of us here have seen," said Pat Gunderson, the Glasgow-based regional supervisor for Montana Fish, Wildlife and Parks. "Right now it's going to take a few years to get things back to even a moderate population."

In North Dakota, state wildlife chief Randy Kreil described the outbreak as the most extensive and deadly in two decades.

Mule deer, bighorn sheep, elk and pronghorn also are susceptible to EHD, but it is particularly damaging to whitetail herds, animal health experts said. Livestock can be infected but typically show few symptoms.

Researchers say the virus that causes EHD does not infect people and there is no risk of eating or handling infected deer,

More precise estimates of the number of whitetail killed are expected after agencies conduct winter population counts and survey fall hunter success.

Periodic outbreaks of EHD occur in whitetail herds across the country. Wildlife officials say the outbreak in the Northern Plains stands out for the high number of deaths and wide area affected.

Animal health experts suspect it was triggered by an exceptionally wet spring that led to lots of muddy breeding habitat for the biting midges that carry the disease. A warm fall meant the midges lingered and continued transmitting EHD to deer.

The outbreak followed a harsh winter that already had knocked down deer numbers across the region.

In response to those winter deaths, Gunderson said the number of hunting tags offered in northeast Montana was reduced from 5,000 to 4,000. After the EHD outbreak began in late summer, sales of another 2,000 tags were suspended.

In western North Dakota, 1,500 licenses were suspended and the state offered refunds for deer tags already sold. More than 630 people took advantage of the refunds, said Randy Meissner, license manager for North Dakota Game and Fish.

Hunting outfitter Eric Albus in Hinsdale, Mont., said his business ran one archery hunting trip along the Milk River this fall, compared to 40 or 50 hunts in prior years.

"It was horrendous," Albus said, "especially when you couple it with the fact that we lost 40 to 45 percent of our whitetail in the winter."

To satisfy his customers, Albus said he leased alternate properties to hunt on that were up to 350 miles away from Hinsdale.

In southern states where deer have a history of exposure to EHD, death rates from the disease are relatively low, said David Stallknecht with the Southeastern Cooperative Wildlife Disease Study, which has been tracking EHD for more than 30 years.

Whitetail in northern states are more likely to die because they lack the antibodies from previous exposures needed to help fight off the disease, said Stallknecht, a professor in the College of Veterinary Medicine at the University of Georgia.

He said a better picture of the outbreak will come later this year, after state wildlife agencies from across the country submit annual animal mortality data to the Southeastern Cooperative

Notwithstanding the disease's economic impacts to the region's hunting industry, Gunderson said the loss of so many deer along the Milk and Missouri rivers could have an upside.

Along some stretches of the river, a combination of animal grazing and ice jams scraping the riverbank each winter have prevented cottonwood trees from regenerating for decades.

After the region's record spring floods allowed seedlings to take root high up on the banks, where they are more protected, Gunderson said a new crop of trees could thrive with so many whitetail gone.

"We won't have the tremendous deer population browsing on them, so hopefully we'll get the cottonwoods along these river bottoms that will take us through the next 100 years," he said.

There may be biting midgets in Georgia, but they must hide out with the bigfeets and black painters.

EHD does occur in Georgia and across the southeast. EHD outbreaks are seasonal and occur in late summer and fall. In the southeast, mild infections are common and are evidenced by presence of the antibodies in the serum of normal, healthy deer. Our deer, such as in Georgia, have a fairly high innate ("genetic") immunity to the various forms of the virus and generally do not suffer the high rate of mortality experienced by northern and mid-western deer, which have lower immunity. Thus, it may be construed that breeding our deer with northern or mid-western strains could weaken the innate immunity our deer possess.

I don't mean EHD specifically, just a disease outbreak in general. Most likely stemming from an overpopulated non-huntable area and radiating outward to the surrounding herd.

There are much greater and more significant threats than an overpopulated, nonhuntable area

sounds like somebody watched the new 'Contagion' movie :hair:

It hit us pretty hard here in parts of western NC a few years ago, still a much lower-than-normal deer population.

Yep, that's exactly why we need to import a bunch of deer from other areas to deer farms and let them spread their genes and diseases to the wild deer. Of course, the deer will be dead, but they'll have big 'ol horns and will make more aesthetically-pleasing corpses. :rolleyes:

EHD hit our deer over at my Dad's property in eastern Alabama, confirmed by a state wildlife biologist. that was several years ago and they still have not bounced back. Coyotes get most of the fawns, too which doesn't help. They recently trapped 7 large coyotes over 2 weekends.

EHD kills deer all over the Southeast every year, just not in the numbers that were recorded in Montana. It seems to run in cycles in local areas, usually 4-5 years apart. I've seen it kill from <10% to over 40% of a localized population in Alabama, usually on the lower side.

Sorry to hear about the bad Montana EHD problems. Really tough having that along with the bad rough winters the last year or two in the Great Northwest taking out a significant amount of muleys, especially this last winter.
