DNR Announces Primary Results Of Southwest Wisconsin CWD, Deer And Predator Study
MADISON, Wis. (WISCONSIN DEPARTMENT OF NATURAL RESOURCES PRESS RELEASE) – The Wisconsin Department of Natural Resources (DNR) today presented the primary results of the Southwest Wisconsin Chronic Wasting Disease (CWD), Deer and Predator Study to the Natural Resources Board (NRB). A recording of the NRB meeting, including this presentation, is available on the DNR’s YouTube channel.
The purpose of this study was to determine how CWD impacts deer populations. This involved estimating deer survival rates and how they were influenced by CWD.
Fieldwork for this project took place in northern Iowa, Dane and Grant counties. This area was selected for study as it is the region where CWD was first detected in Wisconsin in 2002 and has maintained a high CWD prevalence in the years since.
As part of this study, over 1,200 animals (adult deer, fawns, coyotes and bobcats) were captured, 766 GPS collars were deployed on adult deer and 323 radio tracking collars were placed on deer fawns.
Results
Scientists analyzed data from the sample of collared adult white-tailed deer in order to estimate the differences in annual survival (the probability of surviving from one year to the next) between CWD-infected and uninfected deer. Annual survival estimates are listed in the table below.
Annual Survival Probability
FEMALES
- UNINFECTED: 83%
- CWD-INFECTED: 41%
MALES
- UNINFECTED: 69%
- CWD-INFECTED: 17%
These figures indicate that CWD is substantially reducing the annual survival probability of both male and female white-tailed deer. Reduced female survival lowers the growth rate of the population, and when sufficiently suppressed, may result in population decline.
Specifically, results from this study indicate that when the CWD prevalence rates of females surpasses about 29%, deer populations are expected to begin declining.
Implications
The key takeaways from these results are:
- CWD substantially reduces deer survival rates and suppresses population growth.
- Where CWD prevalence is high, deer populations are likely declining.
- CWD will eventually impact deer populations elsewhere if it continues to spread and increase in prevalence.
If CWD continues to spread and its prevalence continues to increase, populations will likely face further declines. The exact degree of these declines, however, will depend on local harvest and recruitment rates. It is important to note here that researchers do not expect CWD-affected deer herds to become extirpated (completely eliminated in a given area), as deer populations have a strong ability to increase reproduction when deer abundance is lower, due to less competition for food, space and other resources.
The public can learn more about these results by visiting the study’s results webpage.
Looking Forward
It should be noted that the results presented here are the primary findings of the Southwest Wisconsin CWD Deer And Predator Study. Although the scope of this study provides us with a rich dataset from which we can continue to learn about our deer herd and CWD’s impact, there are sure to be more results to come as analysis continues. Additional findings will continue to be released to the public as completed.

Laurel Burleson, a Dane County chef, thinks ugly apples make the best dishes.
One of her goals as a chef and restaurant owner is to save usable produce from the waste bin.
“I know how hard (Wisconsin farmers) work every day, making these products that are delicious and nutritious and for anything to get thrown away just because it’s not aesthetically perfect is just outrageous,” said Burleson, owner of Ugly Apple Cafe.
News with a little more humanity
WPR’s “Wisconsin Today” newsletter keeps you connected to the state you love without feeling overwhelmed. No paywall. No agenda. No corporate filter.
The latest fruit monitoring report from the University of Wisconsin-Madison shows many parts of the state having great harvests, although northeastern Wisconsin orchards suffered from a cool spring. But most apple orchards are busy with the fall harvest. So what do you do with that abundance of apples?
Burleson shared some recipes and her philosophy on cooking with WPR’s “Wisconsin Today.”
This conversation has been edited for brevity and clarity.
Rob Ferrett: What do you like to do with apples apart from just eating them?
Laurel Burleson: One that I really like to do is making apple marmalade. That is shredding apples and preserving them in sugar so that they keep their structure. It’s kind of the opposite of making applesauce.
But we also make a lot of apple sauce and apple butter. That’s a good way to use a lot of apples all at once.
RF: What goes into making apple butter?
LB: Very basically you make applesauce, so just cook down your apples and blend them up. Then you take that applesauce and cook it extremely slowly, either in a slow cooker or in the oven. Cook it down until it’s dark and rich and more closely resembling a peanut butter than applesauce.
From there, you can put in whatever spices you want: cinnamon, ginger, nutmeg, bay leaf. You just have to be careful because whatever you start with in the big batch will get super concentrated and reduced in your end product.
RF: With applesauce or apple butter, do we have to be fussy about the type of apples? Or can we mix and match?
LB: I like to mix and match, especially because the apple season starts really early. Some years you can get the first season apples in July.
They don’t hold very long and they’re very juicy, so they break down really easily, but they are very tart. I like to get some of those early season apples and make them into applesauce and freeze them and then when I have other sweeter varieties later I mix them and then reduce that all down into butter.
RF: You shared a savory recipe with us for pork chops with apple bacon cabbage. Tell us a little bit about this recipe.
LB: It’s really fun for the fall and even into the winter. You can kind of use any kind of variety of apple that’s a little bit tart and it’s OK if it breaks down and blends in because the cabbage is going to maintain its structure.
If the onions and apples melt away into a delicious sauce it’s just fine. But also, if you end up with some apple pieces, then it’s a nice little surprise like a little sweetness.
The Ugly Apple Cafe operates cafes inside the Dane County Courthouse and the City County Building in Madison and sells its products at the Monona Farmers Market.
While the Wisconsin Badgers struggle on the football field, sitting at a disappointing 2-2 through four weeks, some of the program’s former transfers continue to find success.
One of those players is tight end Riley Nowakowski, who transferred to Indiana this offseason after five years with the Badgers. The Milwaukee, Wisconsin, native originally walked on to the program as an unranked outside linebacker. After playing sparingly during his first few seasons with the Badgers, he flipped over to fullback in 2022, then out to tight end after Phil Longo arrived in 2023. Nowakowski totaled 18 receptions for 131 yards and a touchdown from 2023-24; his two years as a primary offensive contributor.
The former Badger is already making significant progress toward those totals, now just four games into his Indiana career. He has four catches for 72 yards and a touchdown, plus one carry for a one-yard score. The versatile fullback/tight end delivered the highlight play of his career during Indiana’s blowout win over Illinois on Saturday, taking a 1st-down screen pass 43 yards to the house.
Wisconsin, meanwhile, has received solid contributions from Montana State transfer tight end Lance Mason. The veteran has 14 catches for 177 yards and two touchdowns to date, leading the team in each of those respective categories.
While Mason has been one of the Badgers’ few bright spots through four weeks, it’s hard to ignore Nowakowski’s emergence as one of Indiana’s dependable offensive playmakers.
