Chronic Wasting Disease Prevalence. Chronic Wasting Disease Prevalence.
Patrick Durkin, the Waupaca-based outdoor writer, had some fun with a recent state Department of Natural Resources press release regarding chronic wasting disease.
The release documenting the unmitigated spread of the always-fatal brain disease among deer, was titled: “Disease sampling results provide current snapshot of CWD in Wisconsin.” Durkin, in a column, jokingly suggested a comparable headline for a report on the sinking Titanic: “Damage-control party assesses condition of ship’s hull.”
Though fewer deer are being tested, the incidence of the disease is up. In the 2014 season, which ended March 31, more than 6 percent of the roughly 5,400 deer tested were positive, a DNR tally shows. That’s an all-time high disease rate; as recently as 2008, it was below 2 percent.
More alarming still, the disease rate among adult male deer has reached 40 percent in north-central Iowa County and around 25 percent in two other sectors. And CWD is no longer found only in southern Wisconsin.
Tami Ryan, the DNR’s wildlife health section chief, calls these numbers “not a good news scenario” but also not unexpected, given that the state is no longer attempting to manage the disease but is instead just monitoring its distribution and prevalence. Earlier attempts to employ more aggressive strategies were abandoned amid intense public opposition.
Now, 13 years after CWD was first discovered in Wisconsin, Ryan says many hunters “just want things to go back to normal.”
That’s not likely to happen. A far more plausible scenario is that the disease will continue to spread, infecting and killing deer, until the number of animals available for hunters is seriously depleted. And then, look out.
“The research we’ve done shows the disease is in an accelerating pace,” says Mike Samuel, a UW-Madison associate professor of wildlife ecology who studies CWD. “It’s going to continue to rise at a rapid pace and it’s going to continue to spread until the people decide we’ve had enough.”
And while Samuel sees no way to get rid of CWD, using currently available strategies, he thinks it can be controlled through management practices. He suggests killing more bucks, among whom the infection rate is highest, perhaps by opening the gun hunting season earlier, when deer rut (mate).
But this, Samuel notes, is when bow hunters do their thing, and they are a powerful lobby group. Past CWD-eradication strategies seen as detrimental to herd size drew opposition from hunters and were axed by lawmakers and Gov. Scott Walker. And Walker’s so-called “deer czar” recommended a more passive approach to CWD.
“We have a lot of ways to manage the disease that are politically unpopular,” Samuel says.
Michael Hansen, a senior staff scientist with the national Consumers Union who has long tracked the spread of CWD and related diseases, is appalled by what’s happening in Wisconsin.
“That’s horrendous news,” he says of the most recent numbers. “Do they not care about an epidemic that is sweeping the state? The science doesn’t matter to them?”
Hansen says the “proper response is to try and get rid of the epidemic, rather than just give up and let it sweep through.” Otherwise, it’s only a matter of time before “you’ve got such high rates that populations begin to crash.”
Dave Clausen, a veterinarian who formerly served on the state’s Natural Resources Board, shares this concern. “The current policy is inconsistent with a long-term healthy deer herd,” he says, diplomatically. What is happening now is exactly what he warned the DNR two years ago would happen, absent an aggressive response: “CWD will continue to spread across the state and will increase in prevalence where it is established.”
Now retired, Clausen calls the state’s willingness to essentially let this happen “a political decision, not a scientific one.” If the scientists are right, and Wisconsin’s deer hunt is devastated, will politicians get the blame?

It isn't going to happen! Durkin is great at crying wolf!!
He fails to take into account the fact that CWD came form Colorado, via the deer farms. Look at Colorado's history of dealing with CWD and you will have all the answers. They've been dealing with it a heck of a lot longer than Wisconsin has.
Numbers can be twisted and turned to what ever you want them to be.
why aren't the scientists using the facts learned in Colorado to numerically demonstrate what does or doesn't work. Or at least the relative effectiveness. Maybe because what the numbers show isn't what they want to accept.
CWD is not the first wildlife disease that we wanted to stop. What about blue tongue? Nature knows how to limit populations and it knows how to keep things from dying out. Millions of years have allowed systems to develop that are self regulating.
We, humans, on the other hand are not very good at solving problems. Have we solved economic inequality, oppression, poverty, political corruption? Or even something we can all pretty much agree we should do something about - starving children?
You can't keep carp out of the great lakes. Zebra mussels out of other waters or garlic mustard out of the woods. Once it gains a life of its own, you can retard it, but its like trying to keep the basement from flooding. A lot of effort (and our dollars) can be spent with no discernible difference in the end result other than being able to say "we did everything we could". Heck the fire department, for some fires, lets them burn themselves out.
Someday, hunting will be for the rich. Those with the time and money to do what they desire. Many will not be able to afford to have a weapon license or the property to hunt on. Land will become more fragmented. Peoples need to say "not in my back yard, you don't" will become popular enough the politicians will pass laws making hunting harder and harder for the common man.
Look at England. The common man there lucky if he can use a pellet gun to hunt rabbits. The rich hunt estates will all kinds of exotic game. Or they travel somewhere like Africa or the various stans to find even more exotic game.
Yes that is a long way off. I am too old to see the final days, but today's young may see it. Hunting numbers are already going down. A often reported reason is they don't have a place to hunt. Statisticians probably have an adequate data set to project the next 50 years. I wish one of them would make their information known.
Time to get off the soap box now and let someone else have a chance.
