Elk Migration and Movement in Jackson Hole: Protecting Wildlife and Drivers

Elk Migration and Movement in Jackson Hole: Protecting Wildlife and Drivers

Migrating Wildlife

do not look both ways before crossing the road

Thousands of elk migrate from the higher elevations of Grand Teton National Park and surrounding areas to lower valleys, seeking food and shelter each winter. This seasonal journey is essential for the survival of the elk herd, but it also brings them into direct conflict with human infrastructure—most notably, busy roads like North Highway 89.

The National Elk Refuge, established in 1912, provides critical winter habitat for the Jackson Elk Herd, which can number as many as 11,000 animals. However, as elk move toward the refuge, they frequently cross North Highway 89, a major route connecting Jackson to the park.

These crossings often occur at dawn and dusk, when visibility is limited, increasing the risk of vehicle collisions. This time of year, elk are on the road in larger numbers, and Jackson Hole Wildlife Foundation, with partners Wyoming Game and Fish and Teton County, has reported a rise in roadkill incidents along this corridor.

The Challenge on North Highway 89

North Highway 89 sees heavy traffic year-round, and during elk migration, it becomes a hazardous bottleneck for wildlife. Data collected by JHWF, Wyoming Game and Fish Department, and Wyoming Department of Transportation shows that wildlife-vehicle collisions are a significant cause of mortality for elk, moose, and deer in the region. For drivers, an unexpected collision with a 600-pound elk can cause severe damage, injuries, or fatalities. Human safety and wildlife preservation are intertwined, making solutions to this challenge a community priority.

Proposed Wildlife Crossings

Teton County, WY

To address the growing problem, Teton County, Wyoming has proposed wildlife crossings and funnel fence at high-risk areas in Teton County, including:

North Highway 89: 3 Crossings (1 Overpass, 2 Underpasses)

  • Wildlife Overpass: This structure allows animals to cross above the road on a vegetated bridge, mimicking their natural habitat. Overpasses are particularly effective for larger mammals like elk and pronghorn that prefer open spaces.
  • Wildlife Underpasses (2): These tunnels provide safe passage beneath the road, offering an effective solution for animals that prefer cover.
  • Funnel Fence: (4 miles) Guided by funnel fencing, the underpasses and overpasses encourage wildlife to avoid the roadway entirely, reducing collision risks.

Teton Pass: 1 Overpass, 3 Underpasses, and a Fish Passage

  • Wildlife Overpass: Similar to the North Highway 89 overpass, this structure will reconnect migration routes over the highway, reducing risks for both wildlife and drivers.
  • Wildlife Underpasses (3): These underpasses will provide multiple safe routes beneath the Teton Pass Highway for animals such as deer, moose, and smaller mammals.
  • Fish Passage: A specialized structure allowing aquatic species to move freely along their natural waterways without obstruction from road infrastructure. This supports fish populations and improves the overall health of the ecosystem.
  • Funnel Fence: (4 miles)  Guided by funnel fencing, the underpasses and overpasses encourage wildlife to avoid the roadway entirely, reducing collision risks.

Camp Creek: 3 Underpasses and 1 Overpass

  • Wildlife Overpass: As with the other overpasses, this vegetated bridge provides a natural, open pathway for wildlife like elk, facilitating their migration while keeping them off the road.
  • Wildlife Underpasses (3): These crossings will guide animals safely below the road, preventing wildlife-vehicle collisions and maintaining connectivity across the landscape.
  • Funnel Fence: (5.5 miles)  Guided by funnel fencing, the underpasses and overpasses encourage wildlife to avoid the roadway entirely, reducing collision risks.

Wildlife crossings, including overpasses and underpasses with funnel fences, are proven to reduce collisions and support healthy migration. A study of similar projects on US Highway 191 near Pinedale, Wyoming, found a 90% reduction in wildlife-vehicle collisions after implementing overpasses and underpasses. This project, monitored by the Wyoming Department of Transportation (WYDOT) and other agencies, highlights the effectiveness of combining crossings with fencing to guide wildlife safely above or below roadways. The Trappers Point crossing has become a national model for mitigating migration conflicts.

Scientists emphasize the importance of open migration corridors for ungulates. Fragmented or blocked movement routes can force wildlife into smaller, less suitable habitats, leading to stress, reduced herd sizes, malnutrition, and disrupted ecosystems. By building crossings, we reconnect critical wildlife movement routes and reduce risks for drivers.

A High-Profile Fatality

The recent wildlife-vehicle collision death of Grizzly Bear 399, one of the most well-known bears in the Greater Yellowstone Ecosystem, highlights the devastating chain reaction caused by wildlife-vehicle collisions. Grizzly 399 and her cub were likely devouring an elk carcass in the Snake River Canyon that was very near to the section of the highway where she was killed. Roadkill draws predators like bears, wolves, and eagles to highways, dramatically increasing their risk of being struck by vehicles. Wildlife crossings can reduce these incidents by preventing collisions that leave carcasses on the roadside in the first place, breaking the cycle that endangers predators and scavengers.

While 399’s passing is a high-profile example of a wildlife-vehicle collision, the need for wildlife crossings extends far beyond any one species or one animal. Her death symbolizes the countless animals—ungulates, predators, birds, and smaller mammals—that lose their lives on roads each year.

Though 399 was internationally beloved and her story has drawn significant attention, she represents all wildlife navigating the dangers of high-traffic areas. We hope her legacy will inspire greater awareness and support for implementing wildlife-friendly crossing structures throughout Wyoming. These solutions have proven effective in reducing fatalities and reconnecting critical habitats, providing a safer future for all species that call this region home.

Give Wildlife a Brake and Nature Mapping: A Community Effort

The Give Wildlife a Brake program, led by JHWF, works to raise awareness and promote safer driving practices:

  • Drive mindfully and observe the speed limit in key wildlife zones like North Highway 89, Teton Pass, and Camp Creek.
  • Stay alert at dawn and dusk, when animals are most active.
  • Observe wildlife warning signs that identify known crossing areas.
  • Report collisions and roadkill to help scientists and officials prioritize safety improvements.

In addition, Nature Mapping Jackson Hole offers an easy way for community members to contribute to wildlife conservation. By becoming a certified Nature Mapper, participants can log wildlife and roadkill sightings using an app. The data collected is shared with Wyoming Game and Fish Department to better understand wildlife movements and identify problem areas. This citizen science initiative empowers residents to actively contribute to protecting the animals that define Jackson Hole.

Give Wildlife a Brake and Nature Mapping also work with local volunteers to monitor wildlife crossings, gather data, and educate residents and visitors about the importance of migration corridors.

Why It Matters

Elk are an iconic part of the Jackson Hole ecosystem. They support a balanced food chain and play a key role in the region’s cultural and ecological identity. Their winter migration has occurred for centuries, long before roads and cars appeared in the valley. Protecting this natural behavior while improving public safety requires collaboration, science, and community effort.

While this blog focuses on elk migration, the need for wildlife crossings applies to all species in the Jackson region, including mule deer. There is no doubt that wildlife-vehicle collisions pose a significant threat, ranking as the third leading cause of bird fatalities each year. Drivers should remain vigilant, as animals crossing the road are often accompanied by others, including offspring or members of a herd, making caution essential for reducing collisions.

Review the Wildlife Vehicle Collision Report to learn more about the scope of this issue and the need for wildlife crossings as a proven solution. Support efforts to fund and implement wildlife crossings and participate in programs like Give Wildlife a Brake and Nature Mapping Jackson Hole to make Jackson Hole safer for wildlife and people.

Sounds of Summer

Sounds of Summer

by Max Frankenberry, Assistant Bird Bander

Jackson Hole has officially entered the season of sun and snowmelt. Tourists are making their way through town to and from the parks, and the bustle around downtown Jackson has gotten exponentially louder. But step outside of downtown to the National Elk Refuge, a Cache Creek trailhead or even your own backyard, and you notice that human sounds aren’t the only noises that get louder this time of year. Choruses of birds at dawn, trills of surprised ground squirrels in the afternoons and the croaks of frogs in the evening remind us that this is quite the time to be alive in the mountains.

These symphonies are enjoyable and relaxing to say the least, but they can also be valuable identification tools for Nature Mappers! Learning to ID bird songs, frog calls and even mammal sounds opens your range of observation drastically. Boreal Chorus frogs may be experts at wetland camouflage, and can even avoid our eyes when we’re right on top of them, but learn to recognize their calls and those hidden creatures become as obvious as a moose in the sagebrush. And what better time to start than the summertime! Many species are the most vocal during this time of year, and a walk down your street in the early morning or in the evening can be a great place to begin soaking in those summer sounds.

Wildlife Identification by Ear Resources

Attached below are some excellent resources for learning amphibian and bird songs in particular. Our Nature Mapping database has been especially lacking in amphibian observations, and we know they are out there! Identifying wildlife by ear is a valuable skill, and practice makes perfect. The more practice you put in, the more species you can confidently Nature Map this summer!

Small Mammals: What Good Are They?

Small Mammals: What Good Are They?

by Frances Clark, Lead Ambassador Nature Mapping Jackson Hole

At this time of year, people see their lawn and gardens riddled with ground squirrels or pocket gophers or their trees chewed to toppling by beaver and ask, “What is the purpose of these pests?”

Small mammals serve as prey for our large mammals and raptors and provide other ecological services, such as aeration and recycling of soil and nutrients. Beaver, our largest rodents, form habitat for many other creatures, although they are a nuisance to homeowners with ponds and aspen plantings.

Uinta ground squirrels are common in sage and grassland habitats, and they find similar features in lawns. They dig tunnels and form sleeping chambers, thereby creating holes and mounds, much to the consternation of homeowners and ranchers. I have nature mapped dozens and dozens of ground squirrels driving out the National Elk Refuge road in spring. Indeed they emerge and mate in April and each pair can produce four to seven young by May, which then scamper about every which-way eating grasses and flowers. Their abundance can seem overwhelming, even repulsive.

Driving out this same route a day in mid-June, I spied several red-tailed hawks, Swainson’s hawks and even golden eagles soaring overhead and a coyote or two trotting through the fields, ears alert. The high-pitched alarm calls of ground squirrels came from all directions. I realized the abundance of raptors was due to the plentitude of squirrels.  Uinta ground squirrels are tasty packets of protein. They are a necessary and timely food source for raising young raptor chicks, red fox kits and coyote pups. And the time is short… Uinta ground squirrels are above ground only three months before they go dormant in August for the next nine months. Many don’t make it.

Other raptors, including northern harriers, prairie falcons and American kestrels, hunt open areas for rodents in sizes appropriate to their body weight. In addition to Uinta ground squirrels, least chipmunks, meadow voles and deer mice are important components of their diets. In old growth forests, red-backed voles nourish northern goshawks and pine martens. Great horned owls also devour small mammals. Fortunately, most small rodents don’t bother us humans.

Another annoyance in cultivated areas is northern pocket gopher. As snow melts, one can see the extensive “eskers” that mark the pocket gophers’ progress underground eating roots, rhizomes and tubers for food. In summer, occasional fresh mounds of soil indicate areas of activity. Rarely does one see a whiskered grey face, with tiny eyes and ears, emerge from a hole. Bear, fox and coyote use their ears to find this plump fossorial (digging) prey. The Teton Raptor Center is monitoring pocket gophers as part of their population studies of the majestic great gray owl. Great gray owls can hear pocket gophers moving under feet of snow and plunge feet first to catch their vital winter meal.

In addition, pocket gophers are particularly important in enhancing soils in mountain meadows. Their prodigious earth movement churns up nutrients, allows water and air to seep into hard-packed soils and provides opportunities for seed germination.

Young beaver move up creeks and irrigation ditches to find new territory to raise a family.  The sound of running water and presence of willows and aspen stimulates dam building. Some of these appealing sites are now landscaped into ponds surrounded by aspen trees. Beaver build dams to impound water to serve as moats and insulation for their lodges, where they raise their young and keep safe. Anyone who has visited Schwabacher’s Landing or Moose-Wilson Road in the park has witnessed the diversity sustained by these industrious rodents. Beaver impoundments encourage willows, sedges and aquatics, which in turn provide food and shelter for ducks, sora, amphibians and moose. The U.S. Forest Service and other groups are moving trapped beavers up drainages to enhance wildlife habitat and also to help with flood control and water quality. While beaver can be pesky in our expanding human habitats, they are much needed in our natural habitats.

Even the most lowly, annoying-to-us critter has a role to play in our ecosystem. While no one wants wildlife in our homes, understanding the importance of each species in Jackson Hole can enhance our enjoyment of the out-of-doors, even in our own backyard.

How to Nature Map Small Mammals:

Nature mappers can help record the use of habitats — both cultivated and wild — by many of our often unseen or unappreciated small mammals. Here are some tips for mapping a few rodents and related species:

Uinta ground squirrels are buffy brown, about a foot long, with short tails. They often sit erect near the entrance to their burrow holes or look like soft lumps of manure on the edge of roads, until they move. We particularly encourage notations on the First of Year (FOY) appearances in March and April and Last of Year (LOY) sightings in late July and early August.

High Uinta Ground Squirrel

Uinta Ground Squirrel

Our other ground squirrel, Golden-mantled ground squirrel, looks like a chipmunk due to two set of stripes on its back, but unlike chipmunks, it does not have stripes on its head or tail. These are mostly found in forests, rocky areas and some shrubby sites, particularly at higher elevations.

Golden-Mantled Ground Squirrel

We have three species of chipmunks: all have stripes on their heads, backs, and to some extent down their tails. Least chipmunk is more likely in the sage flats and runs with its tail straight up. The tail is longer than its body. It is smaller and darker on its belly than the Uinta chipmunk, which is found more in coniferous forests or shrubby areas. Uinta chipmunk tends to have a lighter belly and a wider tail. Unlike the other two species found in Jackson Hole, Uinta chipmunks have a white outermost stripe along their backs (rather than a fairly distinct black or blackish-brown stripe), which is shown nicely in this Berkeley photo. Relatively more brightly colored, yellow pine chipmunk is also a forest species and has orange highlights. These can be very difficult to distinguish. Do your best, but when in doubt leave it out.

Three chipmunks found in Jackson Hole

Northern pocket gophers by their nature are hard to see unless you are lucky. These gray, 8 inch animals have small eyes, tiny ears, and large front feet with noticeable claws.  Their tunnels are obvious either as 3-4 inch rounded eskers left over from winter foraging or fresh mounds of soil about a foot wide and several inches high in summer. This “sign” can be used to indicate areas of abundance in sage flats, meadows or forest openings.

Mice, voles, and shrews are impossible to identify to species; therefore, we encourage nature mappers do their best record the groups. Mice have big ears and long tails. Voles have smaller ears and shorter tails and look relatively compact compared to mice.  Shrews, which are a separate family, have elongate pointed heads with small eyes and ears and many teeth to eat their prey of insects, earthworms and the like. Tails vary in length. Our common species is masked shrew. We do not have moles in Jackson Hole.

Beaver can be distinguished from their relative muskrat by their flat vs. rat-like tails seen while swimming in water. While both have rich brown pelts, beaver are usually bigger with a flatter head and are found among willows or other woody plants, which they use for food and dam building. Muskrats use soft-stemmed cattails, reeds and rushes to form their mounds and for food; therefore, they are more likely in wet meadows and marshes.

Beaver versus Muskrat identification

Beaver (left) has a flat tail while its relative, the Muskrat (right), has a rat-like tail.

Red Squirrels: Many people recognize the wide-eyed, bushy-tailed red squirrel found in forests and porches. Often we hear their chatter in the deeper forest. These tree squirrels are defending their territories and particularly their caches of cones. If you happen to see an active “midden,” pile of cone scales and stalks, take a point. This is an indicator of highly productive trees and possible pine marten habitat.

Bullock’s… Wait, BALTIMORE!

Bullock’s… Wait, BALTIMORE!

by Max Frankenberry, JHWF Assistant Bird Bander

This past Saturday, May 19, 2018, JHWF staff participated in the annual Wyoming Game & Fish Department bird survey of the South Park Wildlife Habitat Management Area, just south of Jackson. Our group of volunteer birders, including enthusiastic Nature Mappers and Jackson Hole Bird & Nature Club members, met bright and early Saturday morning, led by our local bird nerd expert volunteer, Tim Griffith. Tim has been crucial to organizing Game & Fish bird surveys of the South Park area since 2016, which have so far logged 96 different species for the area! Our pack split into two groups, one to tackle waterfowl, shorebirds and raptors around the ponds, the other to take on “Warbler Alley,” the thick cottonwood tree groves hugging the backwaters of the Snake River to the southeast. What an appropriate nickname that was – Yellow Warblers dotted most every tree in South Park, and were joined by the radiant Yellow-rumped, Wilson’s and MacGillivary’s Warblers as well. It was a different traveler from the south, however, that took everyone by surprise.

‘Warbler’s neck’ is a common occurrence on a bird survey.

After a busy four hours of hiking and birding the survey was winding down, and brunch was on the brain. But birding tends to deliver the bombshells at the last moments, and Saturday was no different. Jon Mobeck, our team’s oriole-obsessed leader shouted. “Bullock’s! Wait… BALTIMORE!” In a low hawthorn tree not 50 feet from us, was not only a Bullock’s Oriole, a gorgeous but fairly common bird in Jackson Hole, but next to it was a Baltimore Oriole, a normally much more eastern cousin. Historical records vary, but this bird may be one of less than a dozen ever reported in the state of Wyoming, and likely less than a handful have ever been seen in Teton County. What a find! The Bullock’s and Baltimore seemed to follow each other, flying from tree to tree after one another. Perhaps the Baltimore had lost his way on his normal spring route up from Central America, noticed a bird that resembled his brilliant orange color, and followed that Bullock’s back to our western mountains, far away from his normal east-of-the-plains summer vacation.

It’s moments like these that make us realize how special close-to-home wild places like South Park are. The diversity of wildlife in these areas can be astounding. But problems exist in the fact that unless these places are studied or surveyed, we may never know the rarities or struggling populations there. This is the issue Nature Mapping Jackson Hole is helping to solve – by submitting data from your commute from work, a dog-walk in a Jackson city park or a backpacking trip through the Gros Ventre, you are helping to build our human community’s understanding of the wildlife community that surrounds us. And every data point really is significant! You don’t often find rare birds like the Baltimore Oriole, but it’s very possible that the deer you saw driving home could represent the beginning of a muley movement exploring a new feeding ground in Jackson Hole. The data you enter from these sightings help JHWF’s partners to prepare management decisions that inspire positive interaction between humans and the wildlife moving into these areas. Knowing that your effort can directly benefit our local species is a reward in itself, and who knows – maybe your attention to wildlife developed from Nature Mapping will lead you to that once-in-a-lifetime animal.

A quick step into the dory and a careful shifting of weight with binoculars raised and off we go, five lucky Nature Mappers floating the Snake River on a sparkling Sunday morning. We glide swiftly and smoothly under the Wilson Bridge (with the chittering of swallows and clamor of traffic overhead) and emerge, calling out: “Two, no three Ravens!” “16 Tree Swallows, I think? They move fast.” “Look, a Great Blue Heron!” “No, Osprey!”  “Both!”

As we flow downstream, we scan the shorelines, water and sky, and settle into intervals of excitement and tranquility. A designated Nature Mapper jots down the tally for common species and takes GPS points for unusual sightings. A morning’s count can include eight Bald Eagles, a moose, numerous Spotted Sandpipers, Common Mergansers, Yellow Warblers, nesting Bank Swallows and a flotilla of American White Pelicans. Or perhaps we spy a marmot family basking on a rock, or a beaver up a backwater.

For seven years, Nature Mappers have been gathering data on wildlife thanks to A.J. DeRosa, owner of Jackson Hole Vintage Adventures. A.J. donates his handcrafted wooden dory and an expert boatman every Sunday morning from May to October. With this opportunity for consistent data collection, Nature Mappers have been able to record trends and shifts in species’ numbers and locations over the summer months (May-October), year to year. We are beginning to discern patterns in species’ migrations, nesting locations, and possibly, with time, impacts of flooding, dike vegetation management and river use.

These results are possible thanks to over four-dozen trained nature mappers and friends participating each year. Ace volunteer Tim Griffith schedules the teams and often adds his expertise on the floats. Since Tim started coordinating the trips with A.J., many species’ sightings have increased significantly. Tim has a fine ear and eye for the birds! Please read Tim’s 2017 Nature Mapping Jackson Hole Snake River Float Trip Annual Report here. It includes a species list and numbers; the special conditions of 2017 during the spring flood and its effect; and the season’s variation in eagle numbers. Be sure to contact Tim if you wish to volunteer on a Snake River Float Trip this summer!

snake river float trip wooden boat

“You can’t be unhappy in the middle of a big, beautiful river.” – Jim Harrison

On Sunday, May 6, I had the privilege of participating in my first Nature Mapping Snake River float trip. And what a trip it was!

Along with fellow “bird nerds” Jon Mobeck and Tim Griffith (trip leader/coordinator) and guide Adam “Dutch” Gottschling, I spent two hours of the morning floating the eight-mile stretch of the Snake River between the Wilson bridge and Jackson Hole Vintage Adventure’s Tipi Camp.

Having recently moved to Jackson from the relatively flat plains and forests of the upper Midwest, I have a long way to go before I look up at the grandeur of the Tetons with anything but complete and utter awe. So, had we merely floated for two hours looking only at the river and surrounding mountains, without seeing any wildlife, I personally would have considered my Sunday morning well spent.

That said, we ended up observing over 40 species of birds, mammals and amphibians along the river and in the area immediately surrounding the Tipi Camp. Not bad for the first week of May! (Indeed, I’ve since learned that this is on the high end compared to historic species counts.)

Snake River Float Trip Birding

Highlights included 54 American White Pelicans (the largest number ever recorded on one trip), one Swainson’s Hawk, one Merlin, a Greater Yellowlegs and two moose. Though, based on the excitement in the boat, to call the Merlin and Greater Yellowlegs mere highlights is a gross understatement. For good reason too! It turns out only a handful of each species have been spotted by volunteer citizen scientists since the trips began in 2010.

I’d like to say it was beginner’s luck, but I’ve spent enough time appreciating the wild spectacle that is nature to know that to try to claim any credit is silly at best. Besides, who knows what will be seen throughout the rest of this summer? Either way, this trip was an awesome start to what is sure to be an amazing float trip season. Even without such a notable species list, I feel lucky to have been a part of such an experience—to have spent the morning exploring an area of nature that few have the chance to see in a way that even fewer are able to see it.

JHWF partners with AJ DeRosa’s Jackson Hole Vintage Adventures to provide this incredible opportunity to float down the eight-mile stretch of the Snake River between Wilson Bridge and South Park and to collect important data about the various species of mammals, birds and amphibians that use it. Trips take place every Sunday morning from May 6, 2018 through the end of September. Cost is $30 per participant. To learn more, visit the Snake River Float Trip webpage or call the office at 307-739-0968.
