The Teton County Sheriff’s Office contributed two more variable message signs to a stretch of S HWY 89 as area organizations enacted emergency options to address a challenging winter for wildlife.
We have all seen that this year’s snowpack is making things difficult on wildlife. Mule deer in particular are spending more time in the town and on the roads – wherever they can find easier movement and potential forage. As they join us on the valley floor and move around where we do, the potential for conflict of many kinds increases. An obvious problem arises on our roadways, as high snowbanks both limit driver visibility and make navigation challenging for wildlife. Area organizations and agencies continue to discuss options to address the issue, some having been put in place immediately as short -and long-term strategies to reduce wildlife vehicle collisions are integrated. Here’s an update on the quick-response efforts:
Jackson Hole News & Guide article by Mike Koshmrl (Thursday, January 26)
A small herd of bighorn sheep is frequenting the stretch of N HWY 89 just north of the Dairy Queen near the town limits. Please give them ample space and time to move. Unlike deer and elk, these sheep will obstinately remain on the road.
While a county-wide master plan is in process, an array of short-term mitigation measures have been and will continue to be considered. We are grateful that a good deal of data exists on the relative effectiveness of various measures, which we use to make decisions while also recognizing the constraints of time, resources and feasibility. The planned crossings on South HWY 89 (construction set to begin next spring) will separate animals from the roadway, which data suggests is the most effective way to reduce wildlife-vehicle collisions at scale. According to most research, underpasses and overpasses are 80-90% effective at reducing WVCs, while seasonal wildlife alert signage (i.e. variable mobile message signs) is estimated in the 20-25% effective range, making it an effective emergency measure and complimentary piece within a holistic WVC reduction effort. The master plan will likely include a number of mitigation recommendations to include structures, signs and speed limit adjustments to apply the most effective site-specific solutions across the valley.
What can you do now?
- Be alert and drive for the conditions. Most accidents happen at times of low visibility – dawn, dusk, nighttime or in bad weather.
- Watch for electronic warning signs. These signs are put in places where we know animals are or have recently been crossing the road frequently. They’re not just generic warnings – when you see these signs, watch carefully for wildlife.
- When you see wildlife near roadways – slow down immediately. If you see one animal cross the road, it is very likely more are close behind. Animals near the road are not waiting for us to pass by – expect them to do something unexpected, like dash in front of your car.
- In winter, wildlife often use roads to move about – it’s easier than walking through deep snow. But, sometimes they get onto a road and can’t find a quick place to get off. Give them a brake. Be patient and give them time to find a place to get off the road.
- To protect yourself and your passengers, experts advise that you should not swerve off the road to avoid hitting an animal.
- Familiarize yourself with the wildlife-vehicle collision hotspots (located here) and be even more mindful when driving there. Hint: The flashing fixed radar speed limit signs and digital message boards are located in some of these hotspots.
- Get involved with Safe Wildlife Crossings for Jackson Hole to learn about what we can do to reduce wildlife-vehicle collisions as a community.
- Contact your elected officials to let them know that reducing wildlife-vehicle collisions is a high priority.
- If you see areas where snowbanks are trapping wildlife on roadways or impeding movement unusually, please don’t hesitate to call us at 307-739-0968. We work with local partners to address these issues if possible.
Additionally, if you are a Nature Mapper, record your observations of wildlife around neighborhoods and roadways. Please use the comments fields to share the activity you observe. The more information we collect about locations and behaviors during winter (all seasons, actually), the better we understand as a community how we are interacting with wildlife, with the goal of living compatibly alongside our wild neighbors.
Be especially alert in the areas highlighted on this map!

Wildlife deals with winter in many ways: some leave the valley, many others stay year-round. They may go underground for the duration; adapt their hunting strategies to deep snow–burrowing below or plunging deep; or just keep on moving until they get lucky. Several members of our Nature Mapping community describe how their favorite animals cope:
Amphibians – Debra Patla, Researcher
The four native amphibian species of Jackson Hole have three strategies to get through our harsh winters.
- Western Toads and Tiger Salamanders go underground, under the frost zone where they are safe from freezing.
- Columbia Spotted Frogs survive in water that does not freeze up, such as in underground springs, spring-fed streams and ponds.
- Boreal Chorus Frogs perform a winter miracle – staying near the ground surface under leaves or in small crevices, their bodies freeze in the coldest times and thaw as it warms up. It is a complicated physiological response to winter, shared by only four other amphibian species in North America.
Rarely, chorus frogs make a surprise appearance in winter, in a basement or garage. This has happened in Teton County! Kind rescuers have discovered that you can help them survive until spring by providing a box with moist, clean vegetation in a cool, dark place.
Beaver: Kari Cieszkiewicz, Winter Naturalist, National Elk Refuge
Beavers are highly industrious rodents that depend on meticulous winter preparation for survival. Before the first significant snowfall, beavers have already winterized their lodges and cached enough food, such as aspen, willow and cottonwood cuttings, for months. Since their teeth continuously grow, beaver must chew regularly on bark to maintain their teeth! These highly productive animals spend the summer months obsessively monitoring their ponds, ensuring that their dams are supporting enough water so ponds do not freeze to the bottom or prohibit access to their lodges.
Short-tailed Weasels (Ermine) – Kari Cieszkiewicz, Winter Naturalist, National Elk Refuge
Short-tailed weasels are highly adapted, masterful carnivores that have a surprisingly commanding presence in winter. Their elongated, slender bodies facilitate easy movement through tunnels in the snow, leading them to unsuspecting mice and voles. When the prey is bountiful, weasels will often store their leftover prey in caches beneath the snow for later feasting! During the winter months their fur changes color from tawny-brown to white, allowing them to be camouflage as they discreetly move across the snow.
Boreal Owl – Susan Marsh – Writer, Naturalist
Among our forest winter residents is a small predator, the Boreal Owl. Their coloration allows them to blend in well when perched in a tree so they are easily missed, but in the spruce-fir forests of winter, they are likely around. They hunt small mammals by ambush, from red-backed tree voles to squirrels. The photo, taken by Jim Hawley in lower Cache Creek, shows a Boreal Owl having just caught a red squirrel.

Interesting adaptations that are especially helpful in winter include the asymmetry of the owl’s ears, found in other owl species as well. One opening is higher on the skull and the other much lower. The positions help the owl tell where a sound is coming from. I tried cocking my head in mimic but was woefully inept at finding a flock of chickadees without my eyes. The owl, on the other hand, can locate prey even under the snow.
Great Gray Owl – Katherine Gura, Field Biologist, Teton Raptor Center
A boreal forest raptor species that is circumpolar, found in the northern reaches of North America, Europe and Asia, Great Gray Owls are well-suited to brave the long, harsh winters in Jackson Hole. Locally, Great Gray Owls generally migrate down in elevation in wintertime and are often seen grouped up in the Snake River bottom where presumably there is less snow and more prey available. Equipped with exceptional hearing abilities, Great Gray Owls hunt primarily by sound and penetrate through as much as two feet of snow to capture rodents that are not visible.

Rough-legged Hawk – Katherine Gura, Field Biologist, Teton Raptor Center
While many species (and people) in Jackson Hole are “snowbirds,” spending summers here and wintering farther south in warmer climes, the Rough-legged Hawk is an exception. In summer months, Rough-legged Hawks breed in the arctic tundra, then migrate south to spend the winter in more “mild” areas in southern Canada and the northern United States. This past year, a Rough-legged Hawk outfitted with a transmitter in northwestern Wyoming migrated north through Alberta and the Northwest territories and finally summered in Nunavut before returning south this fall through Manitoba, Saskatchewan and Alberta. In the wintertime, look for these hawks perched on fence lines and power poles in open areas in the Valley.

Coyote: Kari Cieszkiewicz, Winter Naturalist National Elk Refuge
As the sun begins to cast its warming light on the snow-covered meadow, a coyote can be seen making very thoughtful, directed movements. Beneath the snow there is a secret society of critters that live in the subnivean (under snow) zone and the coyote can sense their presence. Using its powerful nose, the coyote sniffs at the ground and precisely locates its prey. With one powerful and swift dive-bomb into the snow head-first, the coyote emerges with its breakfast. Based on what prey is available, coyotes are highly adaptable, adjusting their hunting techniques based on their food source.
With its long legs and large body, moose are adapted to deep snow and long winters. When deep snow is present, moose are surprisingly sedentary, tending to range over very small areas, browsing on shrubs. Surprisingly, moose may move to high elevation conifer forests during the winter, foraging on lichens that hang from conifer boughs. The large body size of moose affords them a favorable surface-to-volume ratio that increases their heat retention, a distinct advantage over smaller ungulates such as deer.

JHWF Board Member Bruce Pasfield tries to get an accurate count of Trumpeter Swans on the stretch of Flat Creek within the National Elk Refuge.
Temperatures never rose above zero during the 2016 Christmas Bird Count on December 17, but it was filled with the warmth of a wonderful tradition and the thrill of joyful interaction with the birds of winter.
According to Bert Raynes, the Jackson Hole Christmas Bird Count “got started 60 years ago and covered mostly good bird spots in and around the Murie Ranch near Moose. The counters were a plucky but small group, including Olaus and Adolph Murie and presumably their wives and some other locals.” The Audubon Society sponsors more than 2,500 annual international censuses of birds in North and South America at year-end. Susan Marsh organizes our local count and animates it with her nature-loving spirit.
The Jackson Hole Wildlife Foundation sent a team of two staff members (Kate Gersh and Jon Mobeck) and a board member (Bruce Pasfield) out into the field to join the count. Fueled by a good breakfast and conversation with fellow counters at Bubba’s, “Team Goldeneye” got on the board early with a Northern Shrike observation just below the National Museum of Wildlife Art. Driving along the highway north out of town, the team spotted several Common Ravens and viewed ten Trumpeter Swans beyond the dry rushes on a stretch of Flat Creek’s open water.
Moving farther north, “Team Goldeneye” stopped at the Fish Hatchery Pond to record waterfowl amid the fog from the frigid water. Here, the first six of 17 Barrow’s Goldeneyes introduced themselves along with 10 Mallards and a pair of Common Mergansers. While binoculars were set down for a moment to allow fingers to thaw, a Bald Eagle flew high above the pond eastward toward the Sleeping Indian, the first of three Bald Eagle observations. Let us not forget to mention the five Buffleheads we saw at the pond before piling back into the car. A curiously wandering crew, “Team Goldeneye” zipped past the Gros Ventre Junction for a short distance before circling back. While cruising just outside of its territory, Pasfield spotted some wings flapping in the sagebrush. Just as the one bird was definitely recorded as a Greater Sage Grouse, a flock of another 24 descended onto the flats to hide in the sage nearby. A beautiful sight!
The Jackson Hole Christmas Bird Count is a terrific holiday tradition, punctuated by a passionate cast of friendly characters who love to follow birds around the valley. The Jackson Hole Wildlife Foundation is grateful for each of them, and honored to have shared in the experience with many members of the Nature Mapping Jackson Hole family.

JHWF ED Jon Mobeck presents on the artistry of citizen science and the conservation legacy informing Nature Mapping Jackson Hole.
Earlier this month the University of Wyoming Biodiversity Institute hosted the first ever Wyoming Citizen Science Conference in Lander. Several representatives from the Jackson Hole Wildlife Foundation (JHWF) and Nature Mapping Jackson Hole (NMJH) attended the conference with the aim of learning from other citizen science practitioners across the state and of sharing what we have learned from the past eight years of running our program. The conference proved to be very valuable.
The variety of citizen science programs represented was immense and indicative of the breadth and depth available in Wyoming. For example, modeled on NMJH, Laramie sponsors both a winter and summer “Moose Day” with up to 38 transects and over 80 volunteers. Rocky Mountain Amphibian Project conducted a survey of chytrid fungus in frogs and toads throughout the state, including Teton County. A PhD student studied how geo-tagged imagery can enhance surveys by providing follow-up ID, unbiased assessments, and long-term documentation of plants and animals. Museums around the country are recruiting citizen scientists to review historical specimens, including label information on University of Wyoming herbarium sheets. Road Scholar (formerly Elderhostel) volunteers are chronicling archaeological sites in the Wind River Mountains. Associated with the North American Butterfly Association, twenty citizen scientists have tracked approximately 28 species of butterflies in a count circle in Lander for a decade. These are only a few of the amazing projects presented.
The core focus of the conference was on the problems and solutions that citizen science program managers and volunteers face. Several speakers talked about the difficulty of designing data sheets that capture essential information while also being user–friendly. Project directors need to enter and analyze data relatively quickly to keep citizen scientists engaged: volunteers are rewarded by seeing results of their work. Social occasions help build a concerned community. While ensuring quality remains challenging, with sufficient training citizen scientists produce solid scientific data. For instance, the Rocky Mountain Amphibian Project compared the quality of data collected by volunteers vs. bio-techs with very similar results. In short, presenters concluded, “Citizen scientists rock!” And we have a lot to learn from each other.
Our role in the conference:
On the whole, 65 conference participants came from across Wyoming, and even Idaho and Vermont too – all from a mix of individual citizen scientists, nonprofit organizations, primary and higher educational institutions and federal agencies.
JHWF was a silver-level sponsor for the Wyoming Citizen Science Conference, and our Associate Director Kate Gersh served on the program planning committee, which helped select presenters and set the agenda. Over the course of nearly two full days, here are a few programs that were presented by JHWF board, staff, and partners:
- “Lessons Learned: Eight Years of a Citizen Science Program in Jackson Hole” – Aly Courtemanch
- “Values Driving Conservation: Citizen Science as Interactive Art” – Jon Mobeck
- “Fundraising for Citizen Science: Experiences and Advice” – Kate Gersh, Anya Tyson, Wendy Estes-Zumpf, Frances Clark (in absence)
- Poster Presentation: Nature Mapping Jackson Hole: Mapping Community Solutions ̶ Kate Gersh
- Poster Presentation: Monitoring Wildlife Crossings on South Highway 89 ̶ Paul Hood
- “Bringing Citizen Science into the Backcountry: Emerging Best Practices to Engage Outdoor Education Organizations” – Anya Tyson
- Screening of Far Afield: A Conservation Love Story
Importantly, one of NMJH’s lead volunteers Tim Griffith attended the conference and contributed much to the conversation. Based on the latter and the abovementioned, we believe we successfully expanded awareness of Nature Mapping Jackson Hole statewide and regionally, thereby opening opportunities for greater community connections. This was a proud experience for us and we feel honored to have represented on behalf of everyone who has been involved with NMJH.
Next steps for Citizen Science
What comes next? Well, based on survey responses, conference participants have expressed a desire for open communication and collaboration between citizen science groups, as well as, one central location to list project information. The Biodiversity Institute is excited to share that they have begun the process of planning a website to act as a citizen science clearing house. It will provide a forum for discussion around citizen science projects in our region and to glean tips and ideas for best practice. It will also help to incorporate our projects into the classroom. In addition, the idea of a dedicated newsletter for citizen science groups in Wyoming is under discussion.
The hope is that this conference will take place again next year, giving us the opportunity to follow-up on tactics and ideas that were shared. We have much to learn still about volunteer recruitment and retention, fundraising, risk management, data collection and submission, data sharing and dissemination, evaluation and the list goes on. JHWF will be sure to keep you updated on new developments as they come about. Stay tuned as we continue to explore the potential of all that Nature Mapping Jackson Hole has to offer!

One of the perks of working for the Jackson Hole Wildlife Foundation is that occasionally you get invited by local scientists to do really, really cool stuff! Case in point, this past weekend staff traveled into the Gros Ventre Range with a crew of researchers to briefly capture, study and release bighorn sheep. Witnessing a small helicopter carrying blindfolded, restrained sheep at one or two at a time is very cool! This might sound alarming to some, that sheep would be transported from location to location via helicopter, but be assured that the animals are caught in the shortest possible time, with the least amount of stress. Furthermore, the purpose for this “trip of a lifetime” is to conduct science that will ensure the long-term survival of this iconic species of the American West.
The helicopter brings in two bighorn sheep for a gentle landing.
The Wyoming Game and Fish Department (WGFD) is continuing its multi-year research project on bighorn sheep in the Jackson Region. On December 10 and 11, 2016, 10 female bighorn sheep (previously fitted with radio collars) were captured for disease testing in an effort to learn more about their survival and migration patterns. Samples were collected to test for respiratory pathogens that can cause pneumonia. In addition, researchers from Dr. Kevin Monteith’s lab at Wyoming Cooperative Fish and Wildlife Research Unit at the University of Wyoming performed an ultrasound on each animal to measure body fat. This is a three-year study evaluating how body condition is related to pneumonia outbreaks.
The Jackson herd, which numbered 500 animals in the 1990s, has experienced two significant die-offs in recent years. In 2001, it was estimated that as many as 50% was lost due to a pneumonia outbreak and another estimated 30% lost again in 2011. Today it is estimated that the Jackson herd has climbed back to around 425 animals currently.
Kate Gersh and Greater Yellowstone Coalition wildlife program coordinator Chris Colligan assist the research team.
By monitoring individual female bighorn sheep (ewes) through time, researchers are assessing nutritional condition, pneumonia infection, and linking those data to reproductive performance, survival, and nutritional condition in subsequent seasons. At a minimum, they hope to begin to shed light on the complex interactions in the population dynamics of bighorn sheep and help identify possible management alternatives to reduce probability of pneumonia die-offs. For this specific research project, approximately 20 ewes have been collared. During the first three years of this project, biologists are expecting to recapture these same individual sheep each spring and fall to perform the same round of tests and evaluations. The team will go out again in March 2017, and attempt to catch more of their collared ewes to ascertain pregnancy and other health conditions.
JHWF staff is grateful to have been included in this project over the weekend and we thank the WGFD and Wyoming Cooperative Fish and Wildlife Research Unit for allowing us to see first-hand the efforts involved in conducting field research on bighorn sheep. We also thank all those involved for continuing to support wild sheep conservation efforts — you are doing excellent work!

The Jackson Hole Wildlife Foundation received the Citizen of the Year Award for its Wildlife Friendlier Fencing Program on Thursday, November 17, at the Annual Meeting of the Wyoming Chapter of The Wildlife Society in Cody, Wyoming.
The Wyoming Chapter of The Wildlife Society Board Member Ben Wise announced the award at the closing evening banquet at the Buffalo Bill Center of the West. Wise introduced JHWF’s Executive Director Jon Mobeck to accept the award on behalf of the many hundreds of volunteers who, collectively, were recognized as Citizen of the Year. The Society typically gives the award to individuals who have made a significant contribution to wildlife management. Wise and other nominating agency partners from Wyoming Game & Fish and the Bridger-Teton National Forest saw an opportunity to celebrate the dedicated community that has formed around the Wildlife Friendlier Fencing program. The program’s impact exceeds the 183 miles of fence it has removed or modified over 20 years. It has also served to embody a community’s commitment to a land ethic that highly values landscape permeability.
In a brief acceptance comment, Mobeck alluded to Aldo Leopold’s oft-quoted mantra: “There are two things that interest me: the relation of people to each other, and the relation of people to land.” Mobeck concluded that one benefit of the Wildlife Friendlier Fencing program is that it advances meaningfully both of these relationships. JHWF believes that communities of people that come together for wildlife, especially throughout the rural West, may bridge social divides as we also clear barriers to wildlife movement. Since wildlife is a deeply shared interest in Wyoming – a Western passion – that connects people to each other, we believe that we can weave together the ethical fabric that allows a community to live compatibly with wildlife, while connecting individual communities to each other across a larger landscape. That ensures a bright future for wildlife in the Greater Yellowstone for generations to come.
JHWF Executive Director Jon Mobeck accepts the Wyoming Chapter of The Wildlife Society’s Citizen of the Year award on behalf of program volunteers at the closing evening’s banquet dinner.
The conference in Cody, which brought together 150+ researchers, students and land managers for three days of talks, workshops, films, field trips and social gatherings, reflected this spirit. By promoting collaborative science and land management – and refreshingly linking art and science by inviting the gifted artist James Prosek to deliver the keynote talk at the banquet – the conference aims to build healthy and resilient landscapes for Wyoming’s wildlife and people.
On the opening evening of the conference, JHWF’s film “Free to Roam” was screened to a receptive and engaged audience. “Free to Roam” captures the essence of the Wildlife Friendlier Fencing program and many of the individuals who have been involved since its origin.
JHWF’s Board President Aly Courtemanch and Associate Director Kate Gersh also attended the conference, which enabled the organization to make many valuable connections to extend its reach, and learn from some of the best wildlife managers and advocates in the state.
The Wildlife Friendlier Fencing Program endures because of the relentless volunteer commitment of many individuals as well as the financial support of individual donors and many foundations and agencies over the years. Thank you to all who have made a contribution to this effort!
