Wyoming CWD had been detected in 35 of 37 (95%) of mule deer herds and detected in 24 of 34 (71%) designated elk herd units
Wyoming Game and Fish Department 2025 Chronic Wasting Disease Surveillance Report
Overview
Since its initial detection in Wyoming (1985) chronic wasting disease (CWD), a fatal prion disease of cervids, continues to spread across the state (Figure 1). The Wyoming Game and Fish Department (WGFD) CWD surveillance program focuses on two to three herd units from the eight WGFD regions each year. Efforts are concentrated on hunter-harvested adult male deer and adult elk (both sexes), with a sample target of 200 (collected within 1-3 consecutive years) in most deer and elk herd units. In non-endemic areas, where CWD has not been detected, opportunistic surveillance continues and utilizes hunter-harvest, road-kill, and animals showing signs of the disease or found dead with no apparent cause. This design allows for adequate sample sizes without exceeding the WGFD’s Wildlife Health Laboratory (WHL) testing capacity. Figure 1. 2025 Statewide CWD distribution: All species (based on hunt area and National Park boundaries).

Surveillance and CWD Prevalence
Wyoming’s CWD surveillance strategy was revamped in 2019 to provide a more statistically accurate disease prevalence. This updated strategy required at least 200 hunter harvested samples, from each herd (mule deer and elk), within a 5-year period, focusing on adult male mule deer and adult elk from both sexes. While this approach has allowed for disease data to be collected from a larger sample of species and areas, statistically significant sample sizes are still lacking in many herds. Disease prevalence estimates may be biased due to agency objectives, hunter success, hunter interest, and ease of access to sample collection.
2025 CWD Surveillance
Deer, elk, and moose samples were collected from across the state, through WGFD operations (check stations, field personnel and regional offices), with additional opportunistic samples collected with help from outside partners (meat processors, taxidermists, hunters and federal agencies). Retropharyngeal lymph nodes were predominantly collected due to their ease of extraction and suitability as a diagnostic tissue. Teeth were collected whenever possible to evaluate age structure, and age specific CWD prevalence within herd units.
The WHL is accredited for CWD diagnostics and utilizes enzyme-linked immunosorbent assays as the primary diagnostic tool. Immunohistochemistry is utilized as a confirmatory test when necessary. Individual CWD test results are available on the agency’s website within three weeks of sample submission.
Priority Deer and Elk Herd Units for 2025
The Sublette and Wyoming Range mule deer herds, along with the Afton, Fall Creek, and Jackson elk herds are prioritized annually. For mule deer, the 2025 CWD surveillance focused on fourteen herd units which included mandatory sampling in six hunt areas (Figure 2). For elk, the 2025 CWD surveillance focused on six herd units (Figure 3).

2025 Results and Discussion
The WHL analyzed a total of 5,370 deer, elk, and moose, with CWD being detected in 842 of those samples. This total includes samples from all surveillance categories (hunter-harvest, road- killed, and targeted (animals exhibiting signs of CWD or found dead with no discernible cause), and all sexes and age classes (Table 1). Table 2 outlines samples received from hunter-harvest adult (>2 years old) male deer, adult elk and adult moose (both sexes). Overall submissions increased from 2024 (5,276).

As of December 31, 2025, CWD had been detected in 35 of 37 (95%) of mule deer herds and 111 of 127 (87 %) of mule deer hunt areas. For elk, CWD had been detected in 24 of 34 (71%) designated elk herd units and 50 of 105 (48%) of elk hunt areas.
In 2025, statewide CWD prevalence in hunter-harvested, adult, male, mule deer was 21.6% (95% CI: 16.9% - 22.6%), representing an increase from 2024 (19.4%; 95% CI: 15.5% - 20.4%).
Statewide prevalence in hunter-harvested, adult, male white-tailed deer was 32.1% (95% CI: 22.6% - 34.2%) in 2025, an increase from 2024 (29.2%; 95% CI: 21.1% - 31.1%). Finally, in 2025, statewide CWD prevalence in hunter-harvested adult elk was 2.4% (95% CI: 2.0% - 2.8%), a slight increase from 2024 (2.3%; 95% CI: 2.0% - 2.8%).
To determine CWD prevalence in individual herds, five-year averages were calculated (Figures 6 and 7). Of those herds, with adequate sample sizes, the ‘Project herd’ continues to have the highest CWD prevalence in the state at 61.9% (95% CI: 31.6% - 68.9%), followed by ‘Goshen Rim’ at 36.1% (95% CI: 21.0% - 43.4%) and ‘Southwest Bighorn’ at 30.5% (95% CI: 18.6% - 36.7%). The ‘Iron Mountain’ elk herd had the highest CWD prevalence, of those elk herds with an adequate sample size, at 9.8% (95% CI: 6.9% - 12.4%), followed by ‘North Bighorn’ at 8.7% (95% CI: 5.6% - 12.0%) and ‘South Bighorn’ at 5.0% (95% CI: 2.6% - 8.4%).

CWD detections are not usually ubiquitous across a herd. While disease prevalence can provide wildlife managers with a general perspective on the amount of disease within a population, distinct areas of higher disease occurrence may provide better direction for targeted management action (Figures 9 and 11).

Sampling Effort in Non-Endemic Hunt Areas
As of the end of 2025, 13% of Wyoming’s deer hunt areas and 52% of elk hunt areas have not had CWD detected. Opportunistic surveillance for the disease continues in the non-endemic areas by utilizing hunter-harvested, road-killed and targeted animals (Table 3). Adequate sample sizes in these hunt areas are critical for early detection of the disease as management strategies can change with the status of CWD prevalence.

CWD in Western Wyoming and the Elk Feedgrounds
In 2025, CWD was detected in two new deer hunt areas, and four new elk hunt areas in western Wyoming. Between 2021 and 2025, CWD was detected in twenty-one deer and fifteen elk that were collected from hunt areas that contain at least one elk feedground. Of those detections in elk, nine were collected within the boundaries of a feedground. Those feedgrounds included Dell Creek (6), Black Butte (1), Horse Creek (1), and Scab Creek (1). Elk herds utilizing feedgrounds are annually prioritized for hunter harvested CWD sampling and the department continues to actively monitor and sample any mortalities on/around the feedgrounds to increase surveillance numbers. The department is currently developing Feedground Management Action Plans that will include a section on disease mitigation and management.
CWD Management
With CWD prevalence increasing in the Project mule deer herd (>50% in buck mule deer), the hunt area 157 type 1 deer season was replaced with a general season in 2025. Licenses for Type 3, 6 and 8 were also increased. These changes were made to decrease mule deer densities and limit the spread of disease to adjacent deer herds. Five-year average CWD prevalence (2021- 2025) in the Project herd can be seen in Table 4. Sampling and detection density for 2021-2025 can be seen in Figures 12 and 13.

Since identifying its first cases of CWD in captive deer in the 70s and finding the first wild infected deer in 1985, Wyoming has seen the disease slowly spread throughout the state. CWD has now been documented in members of the deer family in most of Wyoming’s deer hunting areas, with 20% to 40% percent of mule deer affected in some herds. A 2017 study estimated a 21% annual population decline as a result of the fatal disease.

How does CWD impact deer, elk, and moose populations?
Recent research in Wyoming has demonstrated declines in both mule and white-tailed deer populations in deer hunt area 65 due to CWD (see below for citations). These declines are in the core endemic area where prevalence is highest. In areas with lower prevalence, effects of CWD are poorly understood but are considered additive along with other factors that can negatively affect deer populations in Wyoming (i.e. habitat loss, predation, other diseases). The distribution and prevalence of CWD in Wyoming elk is less than that of deer. Currently there are no documented direct population impacts in Wyoming elk from CWD; however, research from Rocky Mountain National Park suggests that CWD could impact elk populations at higher prevalence (13%). While CWD has been found in free ranging moose, there have been few detections, and there is no evidence that CWD is currently having an impact on moose populations.

Wyoming Wildlife Health Lab tests more than 5,200 CWD samples in 2024, CWD was detected in 726 of those samples
Wildlife Health Lab tests more than 5,200 CWD samples in 2024
POSTED: MAY 19, 2025 | CHEYENNE REGION NEWS
NEWS LARAMIE — The Wyoming Game and Fish Department’s Wildlife Health Laboratory tested 5,276 samples from big game animals for chronic wasting disease in 2024. Testing was completed earlier this year and samples were submitted from throughout the state.
CWD was detected in 726 of those samples submitted.
Jessica Jennings, Game and Fish wildlife disease specialist, said samples were submitted from hunter-harvest, road-killed animals and animals found dead or that were euthanized. CWD is a chronic, fatal disease of the central nervous system in mule deer, white-tailed deer, elk and moose. It belongs to the group of rare diseases called transmissible spongiform encephalopathies. These disorders are caused by abnormally folded proteins called prions. Early in the disease animals don’t show any clinical signs. Later on, affected animals show progressive weight loss, reluctance to move, excessive salivation, droopy ears, increased drinking and urination, lethargy and eventually death.
The number of samples submitted and tested in 2024 increased slightly from previous years. In 2023, 5,100 samples were submitted, a decline compared to 2022, when 5,875 samples were submitted. The percentage of samples that tested positive in 2024 was 13.8%, which remained similar to 2023, when 13.9% of samples tested positive.
The proportion of positive samples in 2024 was slightly higher than in 2022, in which 12.3% of samples tested were positive. However, Jennings said comparing the number of positive tests each year can be misleading because Game and Fish’s CWD surveillance program focuses on different deer and elk herd units each year.
Additionally, the number of positives is proportional to the prevalence of CWD in the particular herd unit surveyed. “We can say that the prevalence of CWD is slowly increasing in many deer and elk herd units in the state,” Jennings said.
“In 2024, CWD was detected in three new deer hunt areas, three new elk hunt areas and for the first time on an elk feedground.” Jennings said the lab, which consists of four permanent employees and three contract employees, spent the majority of the hunting season conducting CWD testing with peak testing occurring in October and November. That doesn’t include surveillance preparation, data entry and writing reports once the testing season is over. The majority of the test samples this year were collected by Game and Fish field personnel at hunter check stations or through regional offices. “Chronic wasting disease is a major concern for Game and Fish and we thank hunters who contributed samples from their deer, elk and moose,” Jennings said. “These samples are instrumental in helping us better understand the prevalence and distribution of this disease in our state.” For more info on CWD, please visit the Game and Fish website.

CWD found in new Wyoming hunt area
PINEDALE — The Wyoming Game and Fish Department has confirmed the presence of chronic wasting disease in two adult female elk from Elk Hunt Area 87. The first elk was found dead in January, followed by the second in early February. Both elk were discovered at the Dell Creek feedground. Department personnel have investigated the sites, collected samples and removed the carcasses.
Elk Hunt Area 87 is located in the Pinedale Region. It is bordered by two CWD-positive elk hunt areas: 84 and 92. This marks the first recorded cases of CWD in Hunt Area 87 and is the first detection of the disease within the Upper Green River Elk Herd. This is the second confirmed instance of elk testing positive at a feedground, following a previous detection of CWD at the Scab Creek feedground in December.
”It is unfortunate and concerning to find CWD on an elk feedground;” said Wildlife Division Deputy Chief Justin Binfet. “However, it was not unexpected given this disease continues to spread throughout the West. In anticipation of the spread of CWD to elk feedgrounds, the department created its Elk Feedground Management Plan, which will guide wildlife managers to work to minimize and mitigate CWD risks and look for long-term solutions to disease transmission on feedgrounds.”
CWD is 100 percent fatal to infected deer, elk and moose. Continued monitoring of CWD over time is important to help Game and Fish understand the potential impacts of the disease, as well as evaluate future management actions. Department personnel will continue to closely monitor feedgrounds for elk showing signs of CWD.
Game and Fish personnel from the Jackson and Pinedale regions are currently developing the first Feedground Management Action Plans (FMAPs) for the Jackson and Pinedale herds. This process aims to identify both long and short-term strategies to reduce the elk's reliance on feedgrounds and mitigate the risks of disease transmission. After completing the initial FMAP process for the Pinedale Herd, the Region will determine which herd to prioritize next.

LARAMIE - The Wyoming Game and Fish Department’s Wildlife Health Laboratory tested 6,701 samples from big game animals for chronic wasting disease (CWD) in 2022. Testing was completed earlier this year and samples were submitted from throughout the state. CWD was not detected in 5,875 samples and 826 samples were positive. Some samples submitted were not testable.
Jessica Jennings-Gaines, Game and Fish wildlife disease specialist, said those numbers are based on submissions from hunters, road-killed animals and animals found dead or in poor condition.
CWD is a chronic, fatal disease of the central nervous system in mule deer, white-tailed deer, elk and moose. It belongs to the group of rare diseases called transmissible spongiform encephalopathies. These disorders are caused by abnormally folded proteins called prions. Early in the disease animals don’t show any clinical signs. Later on, affected animals show progressive weight loss, reluctance to move, excessive salivation, droopy ears, increased drinking and urination, lethargy and eventually death.
The number of tested samples and positive tests have remained steady for the past three years. In 2021, 6,884 samples were tested with 839 positives and in 2020, 6,496 samples were tested with 829 positives.
However, Jennings-Gaines noted that comparing the number of positive tests each year can be misleading because Game and Fish’s CWD surveillance program focuses on different deer and elk herd units each year. Additionally, the number of positives is proportional to the prevalence of CWD in the particular herd unit surveyed.
“We can say that the prevalence of CWD is slowly increasing in many deer and elk herd units in the state,” Jennings-Gaines said. “The western half of Wyoming has several deer hunt areas where CWD has not been detected, however the disease continues to spread west and was detected in two new deer and five new elk hunt areas last year.”
Jennings-Gaines said the lab, which consists of four employees and three contract employees, spent the majority of the 2022 hunting season conducting CWD testing with peak testing occurring between October and November. That doesn’t include surveillance preparation, data entry and writing reports once the testing season is over.

CHEYENNE - The Wyoming Game and Fish Department’s Wildlife Health Laboratory tested 6,884 samples from big game animals for chronic wasting disease in 2021.
Testing was completed in early January, and samples were submitted from throughout the state. CWD was not detected in 6,045 samples and 831 samples were positive. Hank Edwards, Game and Fish Wildlife Health Laboratory supervisor, said those numbers are based on submissions from hunters, road-killed animals and animals found dead or in poor condition.
CWD is a chronic, fatal disease of the central nervous system in mule deer, white-tailed deer, elk and moose. It belongs to the group of rare diseases called transmissible spongiform encephalopathies. These disorders are caused by abnormally folded proteins called prions. Early in the disease animals don’t show any clinical signs. Later on, affected animals show progressive weight loss, reluctance to move, excessive salivation, droopy ears, increased drinking and urinating, lethargy and eventually death.
The number of tested samples and positive tests increased for the third consecutive year. In 2020, 6,496 samples were tested with 829 positives compared to 5,067 samples tested and 568 positives in 2019. Edwards said comparing the number of positive tests each year can be misleading because the Game and Fish’s CWD surveillance program focuses on different deer and elk herd units each year, and the number of positive cases is proportional to the prevalence of CWD in the particular herd unit surveyed that year.
“That said, we can say the prevalence of CWD is slowly increasing in most deer and elk herd units in the state,” said Edwards, who added CWD was detected in four new deer hunt areas and five new elk hunt areas in 2021.
Edwards said the lab, which consists of five employees and two part-time workers, spent 1,788 hours — the equivalent of 74.5 days — conducting CWD testing. That doesn’t include surveillance preparation, data entry and writing reports once the testing season is over. Additionally, the lab continues to conduct brucellosis surveillance in hunter-killed elk, respiratory disease in bighorn sheep, as well as many other diseases of wildlife across the state.
The majority of the samples this year were collected by Game and Fish field personnel at hunter check stations or through regional offices. Edwards said the number of samples collected and submitted by hunters continues to increase each year.
“Chronic wasting disease is a major concern for Game and Fish and we sincerely thank all those who contributed samples from their deer, elk and moose,” Edward said. “These samples help us better understand the prevalence and distribution of this disease in our state.”
New for 2021, Game and Fish implemented mandatory sampling in deer Hunt Areas 96 and 97, as well as hosted a raffle for hunters who submitted CWD samples from targeted (Tier I) and non-targeted (Tier II) species and Hunt Areas. Both efforts increased interest in sampling and returns.
Winners from the 2021 hunting season are:
Tier I — Ryan Marti, Morgantown, West Virginia: Nosler 48 Special Ed. (28 Nosler) rifle with Leupold VX-5HD 3-15X44MM scope. — Shane Rogers, Ojai, California: Weatherby Vanguard High Country rifle (6.5 CMR) with Maven RS.1 2.5-15X44 FFP scope. — Philip Bunker, Gillette, Wyoming: Maven S.1S 25-50X80 spotting scope. — Christopher Emanuele, Waterford, Pennsylvania: First Lite Clothing Package (Catalyst softshell jacket, Obsidian merino pants, Kiln 250 aerowool hoody).

CWD found in new Wyoming deer hunt area
Game and Fish continues to notify public of new areas where CWD is found
2/7/2022 5:01:50 PM
CHEYENNE - The Wyoming Game and Fish Department has confirmed the presence of chronic wasting disease in Wyoming’s Deer Hunt Area 143. The disease was detected in a buck mule deer found dead in emaciated condition in late January.
Deer Hunt Area 143 is the Pinedale Region. The area is bordered by three CWD-positive areas, 144 and 138; both of which were new areas for CWD in 2021, and Deer Hunt Area 142 confirmed positive for CWD in 2020.
To ensure hunters are informed, Game and Fish announces when CWD is found in a new hunt area. The Centers for Disease Control recommends hunters do not consume any animal that is obviously ill or tests positive for CWD.
Continued monitoring of CWD over time is important to help Game and Fish understand the potential impacts of the disease as well as evaluate future management actions for deer and elk. A map of CWD endemic areas is available on the Game and Fish website. The disease is 100% fatal to deer, elk and moose that have been infected. In 2021, Game and Fish personnel tested 6,947 CWD lymph node samples from deer and elk— primarily submitted by hunters — and continue to evaluate new recommendations for trying to manage the disease.
Please visit the Game and Fish website for more information on chronic wasting disease testing, transmission and regulations on transportation and disposal of carcasses.

Wyoming Game and Fish Department 2020 Chronic Wasting Disease Surveillance Report
May 2021
Overview
Chronic wasting disease (CWD) is a fatal disease of the central nervous system of cervids caused by abnormally folded infectious proteins called prions. This disease was first identified in Wyoming in 1985 in a free-ranging deer from the southeastern corner of the state, and has since slowly spread north and west; now covering the majority of the state (Fig. 1). In consideration of the wide distribution of CWD across Wyoming, the surveillance program was shifted from detection based, to a monitoring based program in those hunt areas where CWD has been detected. Continued monitoring of this disease over time is necessary to understand the potential population impacts as well as evaluate future management actions. To achieve adequate sample sizes, CWD surveillance is focused in only two to three herd units within each Wyoming Game and Fish Department (WGFD) region each year, allowing for coverage of the entire state every four to five years. This approach focuses on adequate sample sizes to monitor the disease without exceeding the WGFD’s Wildlife Health Laboratory (WHL) testing capacity. Monitoring efforts are concentrated on hunter-harvested adult male deer or adult elk (both sexes), with a sample target of 200 (collected within 1-3 years) in most deer and elk herd units. In areas where CWD has not been detected in deer, active surveillance continues and utilizes hunter-harvested, road-killed, and targeted animals (those showing signs of the disease).
In 2019, the CWD testing capacity of the WHL was increased from 8,000 to 15,000 samples per year by splitting the laboratory into two sections. From October 1st through December 31st, A processing laboratory within the WGFD Wildlife Forensics/Fish Health Laboratory is used for sample processing, data entry, and mapping. Sample analysis continues in the main laboratory housed within the Wyoming State Veterinary Laboratory complex.
2020 CWD Surveillance
Hunter harvested deer, elk, and moose samples were collected at points of concentration (i.e., meat processors, check stations, and regional offices). Samples were also collected from road-killed and targeted animals, and from any deer or elk taken with a WGFD issued lethal take permit. In addition, teeth were collected whenever possible to evaluate age structure, and age specific CWD prevalence within herd units. Predominantly retropharyngeal lymph nodes were sampled due to their ease of extraction and suitability as a diagnostic tissue. The WHL is an accredited laboratory for CWD diagnostics and utilized an enzyme-linked immunosorbent assay (ELISA) as the primary diagnostic tool. Immunohistochemistry is also used through an outside accredited laboratory when necessary. Results were reported to hunters in less than three weeks of sample submission, and hunters could obtain results through the WGFD’s website. Hunters having deer or elk test positive

for CWD were individually notified by a letter or email within 48 hours of confirmatory test results.
2020 Results and Discussion
A total of 6,496 deer, elk, and moose samples were analyzed for CWD by the WHL, with 829 being CWD positive. This total includes samples from all surveillance categories (hunter-harvest, targeted, and road-killed) and from all age classes and CWD positive results (Table 1). Total samples received and testing outcomes are further broken down in Table 2, which outlines samples received from hunter-harvest adult (>2 years old) male deer, and adult elk and moose (both sexes). Data in Table 2 are used to determine prevalence estimates used throughout this report.
The 2020 surveillance effort identified four new CWD positive deer hunt areas (HA): HA 25 in the northern Bighorn Mountains, HA 96 southeast of Lander, HA 117 west of Meeteetse, and HA 142 west of Pinedale (Fig. 2). Chronic wasting disease was also documented for the first time in five elk HAs: 45 north of Worland, 67, near Dubois, 75 in Grand Teton National Park, 114 near Laramie, and 123 near Wright (Fig. 3).

Monitoring CWD Prevalence
The WGFD monitors CWD prevalence in all deer and elk herds where sufficient surveillance data exists for meaningful evaluations. Although statistically significant data is absent for many herds, several do have useful data from the 2014-2016 timeframe to allow for an equivalent comparison of prevalence to 2018-2020.
Trends in CWD prevalence varied greatly between several herd units when comparing prevalence between these two relatively short timeframes (Fig. 4). The Goshen Rim, Paintrock, Southwest Bighorns and the Upper Powder River mule deer herd units saw substantial increases in prevalence, whereas the Baggs, Bates Hole, and Upper Shoshone observed only moderate increases. Prevalence remained steady in the Laramie Mountains herd, but declined slightly in the North Bighorn, Sheep Mountain, and the South Wind River mule deer herds. Unfortunately, sample sizes were limited in 2014-17 for the Goshen Rim, Sheep Mountain, Southwest Bighorns, and the Upper Powder River herds, and trends should be interpreted with caution.
The overall five-year CWD prevalence estimates of Wyoming’s mule deer herds are in Fig. 4. It is important to note that hunter harvest of mule deer is primarily male and therefore prevalence estimates do not account for prevalence in females. Chronic wasting disease prevalence in female mule deer is incomplete in many herd units, but has been shown to be lower than that of males in several herd units where females are harvested, as well as in road-killed surveillance data.
The prevalence of CWD in white-tailed deer and mule deer within the same hunt area varies considerably. Prevalence in white-tailed deer can meet or exceed the prevalence in mule deer in some areas, whereas prevalence may remain much lower in white-tailed deer in other areas. Although this report is centered on prevalence in mule deer bucks and adult elk, the WGFD continues to monitor prevalence in all white-tailed deer populations for this disease.
Historic Endemic Area Elk
Trends in CWD prevalence in elk herds within the historic endemic area were also examined. Prevalence remained steady in the Laramie Peak/Muddy Mountain elk herd at 6% (2014-2016 n=300, 2018-2020 (n=419). The Iron Mountain elk herd doubled from 7% in 2014-16 (n=105) to 14% in 2018-20 (n=249). The overall five-year CWD prevalence in Wyoming elk herds shown in Fig. 6.

CWD in Northwestern Wyoming
Chronic wasting disease was found in two new deer HAs as well as two elk hunt areas in northwestern Wyoming. Deer HA 117 near Meeteetse was one of the last deer hunt areas in the Bighorn Basin to become endemic for this disease, while deer HA 142west of Pinedale, is one of just a few new HAs in the southern Bridger -Teton National Forest. Chronic wasting disease was also found for the first time in elk HA 67 near Dubois as well as elk HA 75 in Grand Teton National Park. Over the past five years, CWD has been detected in six deer and two elk that were collected in and around the elk feedground herd units. This raises considerable concern that this disease is becoming firmly established in northwestern Wyoming (Fig. 2 & 3), and how it may affect deer and elk populations in the future.
Sampling Effort in Non-Endemic Hunt Areas
Chronic wasting disease has not been detected in 30 deer hunt areas in Wyoming. Annual surveillance for the disease continues in these areas, utilizing hunter-harvested, road-killed and targeted animals. Surveillance totals animals collected from CWD non-endemic hunt areas are reported (Table 4). It is a WGFD priority to notify sportspersons when CWD is detected in a new area through press releases, emails, and social media.
Table 4. Non-Hunter harvested chronic wasting disease surveillance in non-endemic areas by species, age, and sex
Continuation of Chronic Wasting Disease Surveillance and Monitoring
Surveillance efforts will continue for 2021 priority herds for the next one or two years until the three-year sampling goals are achieved. Four new mule deer herd units (Bates Hole, Black Hills, Paintrock, and Sublette), one white-tailed deer herd unit (Black Hills), and three elk herd units (Medicine Lodge, Sierra Madre, and Wiggins Fork) will be prioritized.

Wyoming CWD TSE Prion has been confirmed in three new elk hunt areas
CWD found in new Wyoming elk hunt areas
Game and Fish continues to notify hunters of new areas where CWD is found
11/1/2021 5:17:51 PM
CHEYENNE - The Wyoming Game and Fish Department has confirmed the presence of chronic wasting disease in three new elk hunt areas in Wyoming. The disease was confirmed from lymph node samples from three hunter-harvested bull elk.
In the Pinedale Region, CWD was confirmed in Elk Hunt Area 98. This hunt area overlays Deer Hunt Area 138 where CWD was confirmed in January.
Additionally, in the Sheridan Region, Game and Fish has identified two new CWD-positive elk areas. CWD was also confirmed in Elk Hunt Area 36 and 129. Elk Hunt Area 36 is surrounded on three sides by Elk Hunt Areas 37, 46, and 35 which have been CWD-positive since 2019, 2020 and 2009, respectively. Elk Hunt Area 129 overlays nine CWD positive Deer Hunt Areas (8, 17, 18, 19, 21, 22, 23, 26, 29) and one CWD negative Deer Hunt Area (31).
To ensure hunters are informed, Game and Fish announces when CWD is found in a new hunt area. The Centers for Disease Control recommends hunters do not consume any animal that is obviously ill or tests positive for CWD.
Continued monitoring of CWD over time is important to help Game and Fish understand the potential impacts of the disease as well as evaluate future management actions for deer and elk. A map of CWD endemic areas is available on the Game and Fish website. The disease is 100% fatal to deer, elk and moose that have been infected. Throughout the fall, Game and Fish has been asking hunters to collect lymph node samples from harvested deer and elk for CWD testing in focused monitoring hunt areas across Wyoming. Hunters are an important component in helping Game and Fish understand the disease and achieve CWD monitoring goals. When hunters submit samples, they are entered into a prize raffle.
“Each CWD sample we receive is valuable for monitoring and understanding the disease,” said Hank Edwards, Game and Fish Wildlife Health Laboratory supervisor. “Please make an effort to submit a CWD sample of your harvest.”
Game and Fish has conducted surveillance for CWD in Wyoming for more than two decades. Based on the past, wildlife managers believe CWD will be documented in new deer and elk hunt areas within Wyoming.
In 2020, Game and Fish personnel tested 6,496 CWD samples and continue to evaluate new recommendations for trying to manage the disease. So far, over 3,600 samples have been tested in 2021.
Please visit the Game and Fish website for more information on chronic wasting disease testing, transmission and regulations on transportation and disposal of carcasses.

Mule deer study raises red flags
Elsa Freise Buffalo Bulletin Via Wyoming News Exchange Jul 3, 2021 Updated Jul 3, 2021
Elsa Freise Buffalo Bulletin Via Wyoming News Exchange
BUFFALO — There are still six months remaining in the three-year study to better understand why the population of the Upper Powder River mule deer herd is in decline, but already biologists have identified concerning trends.
Statewide, mule deer populations have been on the decline. Biologists have identified the Upper Powder River herd, which ranges in Hunt Areas 30, 32, 33, 163 and 169 south and west of Buffalo, as one of the high concerns.
“We just have way less deer than we used to,” said Cheyenne Stewart, the Sheridan Region wildlife coordinator for the Wyoming Game and Fish Department. “We were trying to look at what we are missing that could explain why the population isn’t rebounding.”
The Upper Powder River Mule Deer Initiative is also looking at history and strategies. Stewart said the initiative is pursuing answers to such questions as, “Are there differences in population metrics like survival and fawn recruitment for deer that migrate versus don’t migrate?” and “What is the relation to agricultural areas versus native habitat?
Two years deep into the study, Stewart has identified some red flags.
“Overall poor body condition. When you compare these deer to the famous Wyoming-range deer that migrate record miles, our deer coming into winter (pre-winter) are comparable to their deer after they have been starving, at the end of winter (post-winter),” Stewart said.
The energy required to lactate can contribute to poor body condition, but Stewart said that not enough does are lactating in December to explain the number of deer who enter winter in poor body condition. Stewart said there is some concern that low lactation rates among the herd’s does could mean that fawns are at higher risk for winter mortality because of the lack of addition al nutrition.
Stewart has also identified high mortality rates primary causes of deaths including chronic wasting disease and mountain lion mortality and a high CWD prevalence.
“Even though it’s a small sample size to make that calculation, (CWD prevalence) is higher than we would expect. Based on the data we have now, we are sitting at the mid-teens (15% to 17%) for prevalence in harvested adult bucks. But this time next year, that can be changed a little bit,” Stewart said.
What’s interesting about this project is that the doe prevalence for CWD is around 20%, higher than the adult buck prevalence an unusual occurrence. Game and Fish is curious to see if the adult buck deer prevalence increases, will the doe prevalence decrease, Stewart said.
Game and Fish has implemented several strategies aimed at boosting herd population: generating liberal licenses for animals that prey on deer, reducing doe harvest, treating the habitat to become more resilient to climate change to ensure that important mule deer habitats persist long-term, monitoring for CWD and other diseases and monitoring fawn survival (which has not been alarmingly low). Yet the trends have been consistent.
“Nothing can really explain what was really going on,” Stewart said.
In phase one of the study, each deer selected for the three-year study was fitted with a GPS neck collar and various body measurements were taken. There are 70 running collars. If a deer dies over the course of the year, a new deer will be collared. The study has collared around 110 deer. Blood samples
were collected and will be analyzed for genetics. In addition, samples were collected to test for parasites, and a small sample of rectal tissue was collected to test for CWD. An ultrasound was also performed to assess body condition, Stewart said.
Every December, biologists catch the collared deer to take
the same body measurements. The Upper Powder River Mule Deer Initiative will end in December, with a final capture, the removal of all collars, recording measurements and additional CWD work, Stewart said.

CWD prevalence in North Bighorns elk herd unit
April 07, 2021
SHERIDAN -
In 2019, the Game and Fish Department’s chronic wasting disease surveillance program shifted from monitoring distribution and spread of the disease to concentrated focus on selected deer and elk herds in each administrative region of the state each year. Efforts are made by regional personnel to collect a minimum of 200 tissue samples from harvested animals in each selected herd. This minimum sample size produces a reliable estimate of prevalence, rather than simply detecting presence of the disease in an area.
The North Bighorns Elk herd, consisting of elk hunt areas 35 through 40, was originally scheduled for priority CWD sampling in 2021. However, enough hunter-harvested samples were collected during the 2018 to 2020 hunting seasons to obtain an adequate sample size (n=206).
Test results identified seven positive elk in two of the hunt areas, Areas 35 and 37, for a prevalence rate estimate of 3.4 percent. Both elk hunt areas overlap deer hunt areas with documented CWD in mule deer and white-tailed deer. Distribution of sampling was not uniform between hunt areas, with Hunt Area 37 accounting for 52 percent of the sampling effort and only five samples collected from Hunt Area 39.
“We plan to prioritize this herd for sampling again in 2027,” said Sheridan Region Wildlife Biologist Tim Thomas. “At that time, we will implement protocols to improve equitable sampling across all hunt areas.”
No CWD management actions have been implemented for this herd. Click here to learn more about CWD and read the department’s CWD management plan. - WGFD -

re-Wyoming Legislature Strips Science From WGFC Likely Dooming Elk To CWD Epidemic In The Future
April 27, 2021
Terry Singeltary flounder9@verizon.net
Dear Mr. Singeltary:
Governor Gordon received your April 1, 2021 email titled, “Wyoming Legislature Strips Science From WGFC Likely Dooming Elk to CWD Epidemic in the Future” and he asked that I update you on the actions the Wyoming Game and Fish Department (Department) is taking in regards to chronic wasting disease (CWD) and elk feedground management within Wyoming. First, thank you for your thoughts, input and CWD reference information.
In July 2020, the Wyoming Game and Fish Commission approved the Department’s CWD Management Plan (Plan), which guides the surveillance/monitoring of CWD and a suite of potential strategies wildlife managers may implement in an attempt to manage the prevalence and distribution of the disease in Wyoming’s deer, elk and moose herds. The Plan includes specific details on how the Department will address CWD on elk feedgrounds. Many of the concerns you raise are covered within the Plan. The document is available at:
https://wgfd.wyo.gov/WGFD/media/content/PDF/Vet%20Services/Approved-CWD-Mgmt-PlanJuly-16-2020.pdf
One of the critical Plan components of CWD management on elk feedgrounds is the initiation of a collaborative process that will direct the long-term management of elk feedgrounds, which will include CWD and other diseases. The Department completed Phase I in January 2021. Phase I provided the public and stakeholders with a comprehensive understanding of elk feedground operation and sought feedback to help shape the public process for Phase II. Phase II is in its initial steps and will begin public engagement during the summer of 2021. The feedground legislation you reference will not impact the Department in moving forward with developing and implementing a long-term feedground management plan. I encourage you to be actively engaged in the Phase II process and beyond. For more information on the public elk feedground collaborative process, please go to: https://wgfd.wyo.gov/Get-Involved/elk-feedgrounds
The Department remains committed to utilizing the best available science in managing the state’s cherished ungulate populations. I appreciate your comments, thoughts and concern and look forward to your continued engagement in our collaborative process.
Sincerely, Brian R. Nesvik Director cc: Governor’s Office Rick King, Chief, Wildlife Division Scott Edberg, Deputy Chief, Wildlife Division

Wyoming Legislature Strips Science From WGFC Likely Dooming Elk To CWD Epidemic In The Future
Greetings Honorable Director Nesvik, Governor, WGFC, Wyofiles, Legislatures, Hunters et al,
This is what happens when you let a bunch of legislatures that are oblivious to cwd tse prion science congregate together and remove sound science policy makers from the table, and then dictate junk science from legislators and Government to the people, and they love to do it with Chronic Wasting Disease CWD TSE Prion, and that's why CWD continues to spread, industry running the show from the sidelines.
SCIENCE SHOWS THAT CONTINUED CONGREGATION OF CERVID IN A GIVEN AREA WILL LOAD THE ENVIRONMENT UP WITH CWD TSE PRIONS, AND SCIENCE SHOWS THAT ENVIRONMENT CAN BECOME CONTAMINATED WITH TSE PRIONS FROM 16 TO 21 YEARS!
same thing is happening in Texas with CWD TSE Prion. you let a bunch of deer farmers, breeders, dictate science, and we all lose, but that money keeps flowing, and it does not matter that what they did keeps the cwd tse prion flowing as well.
you keep letting these elk congregate year after year after year in the same areas, with CWD growing exponentially across Wyoming, your playing with fire.
just look at some of these game farms that had upward to 80% CWD infection rate. is that what you want these feed grounds to become?
let's review the science, shall we.
first, let's see what the sixty-sixth Wyoming legislatures did, then the science they refuse to acknowledge, and this could cost the great state of Wyoming dearly.
Furthermore, you cattle ranchers better start paying close attention to these cwd regulations and what these legeslators plan on doing with cwd, and how that might affect you as a cattle rancher, or a pig farmer. you don't want a deer farmer or breeder siding up close to your land, i can assure you.
wait, there's more, CWD has now transmitted to pigs by oral routes, and that's puts a big bulls eye on the feed industry, especially since the BSE 589.2001FEED REGULATIONS for cervid is only VOLUNTARY. the price of TSE PRION POKER has gone up, are you all in $$$
i can only pray that the Governor of Wyoming will shoot this down, and let the scientist do their job.
TSE PRIONS HAVE NO PLACE IN A POLITICIANS HANDS, this has been proven time and time again.
with kindest regards,
i am sincerely,
Terry S. Singeltary Sr.

Wyoming Game & Fish Discovers CWD-Positive Mule Deer in Pinedale, Discourages Feeding of Wildlife ''As of September 2019, CWD has been identified in 31 of 37 (84%) Wyoming mule deer herds, nine of 36 (25%)elk herds, and generally wherever white-tailed deer occur.
Increasing prevalence and distribution of CWD has the potential to cause widespread and long-term negative impacts to Wyoming’s cervid populations.
Prevalence of this disease in chronically infected Wyoming deer herds has exceeded 40%, with one elk herd exhibiting nearly 15% prevalence.''
''for the first time, there is clear evidence that CWD is adversely affecting the overall health and viability of some herds.''

Wyoming Legislature Strips Science From WGFC Likely Dooming Elk To CWD Epidemic In The Future
Greetings Honorable Director Nesvik, Governor, WGFC, Wyofiles, Legislatures, Hunters et al,
This is what happens when you let a bunch of legislatures that are oblivious to cwd tse prion science congregate together and remove sound science policy makers from the table, and then dictate junk science from legislators and Government to the people, and they love to do it with Chronic Wasting Disease CWD TSE Prion, and that's why CWD continues to spread, industry running the show from the sidelines.
SCIENCE SHOWS THAT CONTINUED CONGREGATION OF CERVID IN A GIVEN AREA WILL LOAD THE ENVIRONMENT UP WITH CWD TSE PRIONS, AND SCIENCE SHOWS THAT ENVIRONMENT CAN BECOME CONTAMINATED WITH TSE PRIONS FROM 16 TO 21 YEARS!
same thing is happening in Texas with CWD TSE Prion. you let a bunch of deer farmers, breeders, dictate science, and we all lose, but that money keeps flowing, and it does not matter that what they did keeps the cwd tse prion flowing as well.
you keep letting these elk congregate year after year after year in the same areas, with CWD growing exponentially across Wyoming, your playing with fire.
just look at some of these game farms that had upward to 80% CWD infection rate. is that what you want these feed grounds to become?
let's review the science, shall we.
first, let's see what the sixty-sixth Wyoming legislatures did, then the science they refuse to acknowledge, and this could cost the great state of Wyoming dearly.
Furthermore, you cattle ranchers better start paying close attention to these cwd regulations and what these legeslators plan on doing with cwd, and how that might affect you as a cattle rancher, or a pig farmer. you don't want a deer farmer or breeder siding up close to your land, i can assure you.
wait, there's more, CWD has now transmitted to pigs by oral routes, and that's puts a big bulls eye on the feed industry, especially since the BSE 589.2001FEED REGULATIONS for cervid is only VOLUNTARY. the price of TSE PRION POKER has gone up, are you all in $$$
i can only pray that the Governor of Wyoming will shoot this down, and let the scientist do their job.
TSE PRIONS HAVE NO PLACE IN A POLITICIANS HANDS, this has been proven time and time again.
with kindest regards,
i am sincerely,
Terry S. Singeltary Sr.

AN ACT relating to elk feedgrounds; authorizing the permanent closure of an elk feedground authorized or administered by the Wyoming game and fish commission only upon an order of the governor; requiring the recommendation of the commission and comment by the Wyoming livestock board for the closure of an elk feedground; requiring a public meeting; authorizing the governor to temporarily close elk feedgrounds under emergency circumstances; authorizing the Wyoming game and fish commission to contract or lease private and state lands for relocating elk feedground sites; requiring the Wyoming game and fish department to develop plans for alternative elk feedground sites as specified; requiring a report; and providing for an effective date.
Be It Enacted by the Legislature of the State of Wyoming:
Section 1. W.S. 23‑1‑305 is created to read:
23‑1‑305. Closure of elk feedgrounds; alternative feeding sites; reporting requirement.
(a) Except as authorized by subsection (b) of this section, any elk feedground authorized or administered by the commission as of July 1, 2021 and in accordance with W.S. 23‑1‑302(a)(ix), shall only permanently cease operations or be subject to closure by the department or commission upon a recommendation for a feedground closure by the commission and subsequent order of the governor. Any closure order issued by the governor shall only be valid and lawful upon satisfaction of the following conditions:
(i) The commission shall provide its recommendation to the governor for the closure of the elk feedground and concurrently to the Wyoming livestock board. Upon receipt of the commission's recommendation, the board shall provide its opinion to the governor on whether the board believes the closure of the elk feedground is appropriate;
(ii) The commission, in consultation with the Wyoming livestock board, shall conduct not less than one (1) public meeting in a location that is reasonably calculated to foster the most public participation by the people directly impacted by the proposed closure and by other vested stakeholders. The public meeting shall be held after the commission and the board have acted as required under paragraph (i) of this subsection. The commission shall compile the comments received as a result of the public meeting and provide those comments to the governor for the governor's consideration on whether to issue an elk feedground closure order.
(b) Any elk feedground authorized or administered by the commission may be temporarily closed by order of the governor due to emergency circumstances for a period not to exceed six (6) months after which the feedground shall only remain closed in accordance with subsection (a) of this section.
(c) The commission is authorized to contract or lease private lands or lands owned by the state for the purpose of relocating an elk feedground authorized or administered under W.S. 23‑1‑302(a)(ix), which would otherwise be subject to closure under this section.
(d) For any elk feedground authorized or administered under W.S. 23‑1‑302(a)(ix), which utilizes federal public lands, the department shall report to the joint travel, recreation, wildlife and cultural resources interim committee upon the department receiving notice that the federal authorization permitting the use of the federal public lands will not be reissued or will be revoked. The report required by this subsection shall include draft contingency plans, including associated costs with implementing the plans, identifying any appropriate private lands, lands owned by the commission or lands otherwise owned or under the authority of the state of Wyoming for the purpose of supplementing or relocating the feedground operation that is affected by the expiration of any federal public land authorization. The office of state lands and investments shall cooperate with the commission in identifying any alternative feedground sites consistent with this section.
(e) Nothing in this section shall be construed to prohibit the department from continuing to administer authorized elk feedground operations, including:
(i) Commencing and ending annual elk feedground operations on dates determined by the department; and
(ii) Conducting emergency elk feeding operations when deemed necessary by the department.
Section 2. W.S. 11‑18‑103(a) by creating a new paragraph (xi) and 23‑1‑302(a)(ix) are amended to read:
11‑18‑103. Livestock board; powers generally.
(a) In addition to powers and duties hereinafter provided, the Wyoming livestock board shall:
(xi) Convene when necessary for the purpose of considering the recommended closure of any elk feedground as provided under W.S. 23‑1‑305(a).
23‑1‑302. Powers and duties.
(a) The commission is directed and empowered:
(ix) To make suitable provisions for the feeding of the elk subject to the requirements imposed under W.S. 23‑1‑305, and other game animals, birds, and fish of Wyoming in such localities as may be deemed necessary;
Section 3. This act is effective July 1, 2021.

Wyoming Game & Fish Discovers CWD-Positive Mule Deer in Pinedale, Discourages Feeding of Wildlife ''As of September 2019, CWD has been identified in 31 of 37 (84%) Wyoming mule deer herds, nine of 36 (25%)elk herds, and generally wherever white-tailed deer occur.
Increasing prevalence and distribution of CWD has the potential to cause widespread and long-term negative impacts to Wyoming’s cervid populations.
Prevalence of this disease in chronically infected Wyoming deer herds has exceeded 40%, with one elk herd exhibiting nearly 15% prevalence.''
''for the first time, there is clear evidence that CWD is adversely affecting the overall health and viability of some herds.''

Wyoming CWD found in new Wyoming deer hunt area

Since identifying its first cases of CWD in captive deer in the 70s and finding the first wild infected deer in 1985, Wyoming has seen the disease slowly spread throughout the state. CWD has now been documented in members of the deer family in most of Wyoming’s deer hunting areas, with 20% to 40% percent of mule deer affected in some herds. A 2017 study estimated a 21% annual population decline as a result of the fatal disease.
https://freerangeamerican.us/chronic-wasting-disease-wyoming/#:~:text=CWD%20has%20now%20been%20documented,result%20of%20the%20fatal%20disease.
How does CWD impact deer, elk, and moose populations?
Recent research in Wyoming has demonstrated declines in both mule and white-tailed deer populations in deer hunt area 65 due to CWD (see below for citations). These declines are in the core endemic area where prevalence is highest. In areas with lower prevalence, effects of CWD are poorly understood but are considered additive along with other factors that can negatively affect deer populations in Wyoming (i.e. habitat loss, predation, other diseases). The distribution and prevalence of CWD in Wyoming elk is less than that of deer. Currently there are no documented direct population impacts in Wyoming elk from CWD; however, research from Rocky Mountain National Park suggests that CWD could impact elk populations at higher prevalence (13%). While CWD has been found in free ranging moose, there have been few detections, and there is no evidence that CWD is currently having an impact on moose populations.
