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.

Wisconsin guard Andrew Rohde reflects on early March Madness exit
Wisconsin guard Andrew Rohde said the Badgers ‘thought we could do so many things’ in the NCAA Tournament before it ended abrupty with an upset loss.
Wisconsin men’s basketball has added a sharpshooting wing via the transfer portal.
Miami (Ohio) transfer Eian Elmer has signed with the Badgers, the team announced April 18. The 6-foot-7 wing will join UW with one year of eligibility remaining.
Elmer averaged a career-high 12.7 points and 5.9 rebounds while shooting 49.8% from the field and 42.9% from 3-point range in 2025-26. His production helped the RedHawks go 32-2 and earn an at-large NCAA Tournament bid.
“We are really excited to add another excellent addition to our spring signees,” UW coach Greg Gard said in a release. “Eian brings a wealth of experience and scoring punch as a 6-7 wing. … A terrific shooter, his skillset and production fit excellently into our plan as we build out next year’s team. Throughout our evaluation process, our staff loved his size, power and skill and truly believe he will thrive in our system.”
Elmer is Wisconsin’s third transfer portal addition since the end of the 2025-26 season, joining former George Washington guard Trey Autry and former Hofstra forward Victory Onuetu. UW also added Australian guard Owen Foxwell.
The additions of Autry, Onuetu and now Elmer leave Gard’s staff with three more roster spots to fill ahead of the 2026-27 season.
The Badgers are looking to replace much of their production from a 2025-26 team that went 24-11. Nolan Winter is expected to be the team’s only returning starter after John Blackwell and Aleksas Bieliauskas entered the transfer portal and Nick Boyd and Andrew Rohde exhausted their eligibility.
MILWAUKEE – Friday’s severe storms have passed. And with that, the threat of any severe weather has also passed for the immediate future as no storms or rain are expected for several days.
However, plenty of damage remains across southeastern Wisconsin as of Saturday morning, in addition to the ongoing flooding threat.
Several area rivers are at flood stage, and there are multiple river flood warnings in effect.

How Aleksas Bieliauskas has grown in first season with Wisconsin Badgers
Wisconsin coach Greg Gard has high praise for Aleksas Bieliauskas about a month into the Lithuania native’s freshman season.
MADISON – One of Wisconsin men’s basketball’s departing transfers is headed to an SEC program with some connections to the Badgers.
Ex-UW forward Aleksas Bieliauskas has committed to South Carolina, he announced on April 17.
Bieliauskas left the Badgers after appearing in all 35 games as a freshman and making 28 starts. He averaged 4.9 points and 4.4 points in 20.2 minutes, and highlights of his freshman year included his five 3-pointers in UW’s upset over eventual national champion Michigan.
He’ll join a program with plenty of Wisconsin ties. South Carolina head coach Lamont Paris was an assistant coach at Wisconsin from 2010-17 on Bo Ryan and Greg Gard’s staffs. South Carolina assistant coach Tanner Bronson and director of video services Roman DiPasquale also are UW alumni.
Bieliauskas is the second of UW’s four departing transfers to commit to a new school. Reserve forward Jack Robison committed to North Dakota State on April 15. Starting guard John Blackwell and reserve forward Riccardo Greppi have not announced their next schools yet.
