When Nature Mapping Jackson Hole began in 2009, Project Backyard (PBY) was born. It was the first systematic observation protocol developed for Nature Mapping Jackson Hole, meant to augment the casual observations that people recorded while driving or wandering along the mountain trails. What’s the difference between PBY and casual observations, and why does it matter?
A good example may be taken from our first attempt at counting moose on a single day for Nature Mapping Jackson Hole, prior to the start of the organized Moose Day, for which observers are assigned specific areas. On that first count we had lots of observations, but many of them turned out to be the same dozen moose in the Antelope Flats area. It became clear that casual observations could only give so much accuracy on a single day.
What was the best way to achieve a more systematic approach that would be easy for people to work with? Asking homeowners to record what they saw from their backyards seemed like the answer.
Participants in PBY make weekly observations, recording the maximum number of each species seen during a single week. No need to use a GPS unit – anyone participating in the project enters the coordinates for their location once, and they come up automatically each time. You can do it less frequently than weekly, and you don’t have to sit watching the bird feeder all day – just note what you see.

The response has been remarkable. Over 19,140 observations have been made in Project Backyard. These observations are particularly valuable as they provide information about the wildlife living in, or moving through, our neighborhoods and agricultural lands. While the federal agencies and Wyoming Game & Fish Department conduct wildlife counts on public land, they are often geared toward particular species, such as the classification count each February on the National Elk Refuge. Private lands are not included in agency counts since access is not always granted. But if you live there, you can provide valuable insights. It is through private citizen observations that we know about where small elk herds are moving as they increasingly stay the winter in the Wilson area and elsewhere on the valley floor – especially in this high-snow year. It is through citizen observations that we know the winter of 2016-2017 has been a low year for many species of songbirds that are often seen in higher numbers at feeders.
We collect this information not just for our edification. Nature Mapping Jackson Hole receives requests from the county, environmental consulting companies, researchers, non-governmental organizations and land developers, asking for information about what wildlife species might be affected by upcoming plans. Any data that a private firm or individual receives also go to the Teton County Planning & Development Department. Our data help make good decisions for wildlife in the valley.

Some PBY observers have been providing information since the inception of the project. Others are welcome additions to the group, adding data from new locations that help give us a broader picture of Teton County wildlife. Many PBY observers are located in a few places — unsurprisingly, those areas where people live: Jackson, Wilson, Rafter J and along WY 22 and HWY 390. Others are located in Alta, Buffalo Valley and scattered from Munger Mountain to Blacktail Butte. It would be wonderful to fill some gaps where observations are not being made, including Moran, Spring Gulch and both Gros Ventre Buttes, the south end of the county, Hoback Junction, Kelly and the Shadow Mountain area. Populations are sparse in some of these spots, so there aren’t many backyards from which to observe. But slowly, we are building a valuable database using citizen science, thanks to the dedication of many people who care about the future of wildlife.

![sheriffs-sign-wildlife-on-road](https://jhwildlife.org/wp-content/uploads/2017/01/Sheriffs-sign-Wildlife-on-Road.jpg)
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)
![bighorn-on-road-2](https://jhwildlife.org/wp-content/uploads/2017/01/bighorn-on-road-2.jpg)
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.
![coyote winter survival tactics](https://jhwildlife.org/wp-content/uploads/2017/01/coyote-winter-survival-tactics.jpg)
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.

By Frances Clark, Nature Mapper and Botanist
Hiking under Engelmann spruce trees has been hazardous this fall. Light brown cones, 4-6 inches long and sticky with pitch, pour down amidst harsh chattering from above. I have counted one cone falling every 3-5 seconds, another time I couldn’t keep track of the barrage. Cones landed on my head, bounced and then lay strewn about my feet. Cone storms. What s going on?
Red squirrels are taking advantage of a “mast year.” Last spring, you may remember, prodigious amounts of pollen wafted on the wind. Some of that pollen landed on tiny female cones, which have matured, securing two winged seeds under each scale. Spruce trees are now laden with dangling cones from the top down. This abundance occurs every 2-3 years in spruce. The intervening times are lean.
Well adapted to feast and famine, red squirrels form large middens—stores of thousands of cones. They efficiently sample and then harvest trees with the most seed energy per cone and with the greatest cone abundance. Middens lie at the center of the most productive group of trees.
A midden can best be described as several inches of cone scales and cores heaped over mineral soil, forming mounds up to several feet high and wide. The loose surface often has shallow holes in it. In the mineral soil below, there may be a network of tunnels. Squirrels pack several cones, pointed end down, into holes which will be covered eventually by more scales and cores. In this cool and moist environment—a humidor—cones will remain unopened for at least 1-2 seasons until the squirrels retrieve them. When they do, squirrels eat cones like corn-on-the-cob, scattering scales everywhere while consuming the nutritious seeds. It has been calculated that squirrels consume 50-156 cones a day and stash 10s of 1000s in a midden in a good year. No wonder red squirrels are so territorial – chattering loudly at any perceived threat and dashing out to their territorial boundary: they are defending their stash for winter survival.
![an_redsqu_cache_lsr_6312_2_6x4_q2](https://jhwildlife.org/wp-content/uploads/2016/10/An_RedSqu_Cache_LSR_6312_2_6x4_Q2.jpg)
While cones are preferred, in lean times and in summer, red squirrels will eat other items. Fungi are particularly relished, with parts hung up in trees to dry. They eat buds, fruits, sap, even cambium and phloem, as well as eggs and insects. Small plant parts placed in middens may help train young squirrels for future hoarding. In different years, squirrels may harvest cones of Douglas firs – which have mast years every 4-5 years, or as back up, serotinous cones of lodgepole pine. Lodgepole pine cones are often gathered on top of middens. They do not open even when dry, are too tough for other predators to eat, and seeds remain viable for years. The squirrels don’t need to spend extra energy to bury them.
![piceenge_fr_phllktr_10-9-16_1_s_crp_5x3](https://jhwildlife.org/wp-content/uploads/2016/10/PiceEnge_Fr_PhlLkTr_10.9.16_1_S_crp_5x3.jpg)
The other day, walking around Moose Ponds, I heard several red squirrels churring within a stand of battered old spruce and fir trees. Their density indicated good habitat. Tangles of downed limbs and saplings surrounded straight, scaly boles clad in densely needled branches, which intertwined to form a closed, irregular canopy. Engelmann Spruce reach peak production at 150-200 years and provide diverse cover, escape routes, and nesting sites. Old growth trees are excellent for red squirrels.
As red squirrels are active all winter, nesting sites are vital for thermal regulation. Tree squirrels prefer natural cavities, but these are often in short supply so instead squirrels will build a nest of leaves and grass 12 to 60 feet off the ground. Other options include “witches brooms,” an aberrant growth pattern where twigs are unusually dense. They will also burrow into tunnels under their middens for warmth and safety.
Nest sites are located within 100 feet of larders so squirrels can readily defend and retrieve their stores. Circular territories may be 1-2 acres centered around a midden. I nature mapped six squirrels – six territories – on my route past Moose Ponds. While dutiful, I wish now I had taken more time in this rough old patch of forest to see where the middens and nests might be.
Predators come from air or ground. Squirrels may have different calls depending on whether or not a threat is aerial or terrestrial. One study indicates that red squirrels produce a high frequency, short “seet” sound similar to alarm calls of birds. This sound is hard for raptors, such as Goshawk, Great Horned Owl, or Red-tail Hawk , to locate or even hear. A louder bark call is used for overland threats, such as a Pacific (pine) marten (12-20% of marten diet is red squirrels), weasels, or fox. Once alerted, squirrels scramble and hide in dense vegetation.
Between predation and starvation, only 25% of squirrels survive into their second year. Females are in estrus for one day only in early spring. Many males, one dominant in the lead, will give chase and several may succeed in copulation on that one day. In just over a month, the female gives birth to an average of four young which will be independent in another 70 days, by early fall. While mothers may share a territory with daughters, they kick out sons who must then find and defend their own territories by winter. Often the most successful males have ventured the farthest to find a relatively large territory containing an abandoned midden. Midden sites are often used by many generations. In autumn, youngsters and seasoned squirrels are particularly territorial, defending boundaries while gathering cones, which is why they are so vociferous.
Red Squirrels are the most frequently Nature Mapped small mammal with 305 observations over the last seven years. Even so, many of us pass them by – unrecorded – on our hikes. In your next excursions through a conifer forest, listen for chatter. Can you hear differences in their calls? Can you discover a midden nearby? Does a squirrel bound toward you to defend its territory or scurry up a tree or down into a tunnel to escape? Can you find its nest? All these behaviors are fascinating to watch while you may, or may not, log a new Nature Mapping observation.
