Message from JHWF Executive Director April 12th, 2021

By Renee Seidler | Executive Director

What a great time to be out traveling between Victor Idaho and Farson Wyoming! On Friday, a beautiful sunny spring day, wildlife was on the move and easily seen from the road. My wildlife sightings list in one short day included large groups of elk, mule deer and pronghorn, bighorn sheep, sandhill cranes, vultures, prairie dogs, burrowing owls, bluebirds, and light-colored slatey male Northern Harriers. Enough to give me a grin for days! And lots to report to our Nature Mapping database. 😊

This drive also elevated my vivid awareness of how dangerous this time of year can be for animals moving toward summer range and it reminded me of the work and collaboration we are doing to protect this precious resource. Some updates that may interest you:

In December 2020, at the behest of the Wildlife Foundation and others, the Board of County Commissioners added a statement to the County Transportation Plan that requires a county planning process for WY 390 as a whole corridor. This highway is challenging to mitigate in part due to the dense development and number of access roads. By planning for mitigation at a ‘corridor’ level, the county can move past piece-meal mitigation efforts that have been employed in the past (which have been helpful, in bits and pieces) and create an inclusive plan that makes sense for motorists and wildlife for the length of the roadway. We celebrate this milestone and we look forward to working with the county to create the safest plan for all who live and drive along WY 390 that also preserves and improves habitat for native wildlife that need the “West Bank” to survive.

On the topic of WY 390, our 4 fixed radar signs will be replaced this summer, and an additional radar sign will be added for southbound traffic where the speed limit decreases from 55 to 45 mph. WYDOT has also been scheming additional signs for either end of the corridor that are larger with multiple species represented. These will be similar to other wildlife signs in the county on US 191 and 89.

Planning and design for wildlife crossings at the WY 22-390 intersection is moving along. Construction is slated to begin late 2022 – early 2023. In a similar time-window, the Stilson parking lot is undergoing planning for expansion by JHMR and Teton County. This important work aims to preserve the greater ecosystem by expanding public transit. We are engaging with the county and partners to ensure that wildlife movement in this critical location is not compromised along the way.

A recent federal project was approved to plan for improvements of WY 22 on Teton Pass. This, along with the Stilson plan and another federal project—the BUILD grant— aim to seamlessly tie traffic, transit, and pedestrian flow together from The Village to Driggs, Idaho. We remain vigilant to the process to safeguard wildlife needs for habitat and movement.

Good research continues to help us adaptively improve wildlife crossing structures. Colorado DOT just released results from a study of ~5 years of monitoring over 10 miles of highway mitigation. You may find some of the results interesting…

• Wildlife-vehicle collisions were reduced by 92% where mitigation was installed
• Round-bar wildlife guards (similar to cattle guards) were the best at deterring wildlife breaches
• Elk—a notoriously challenging animal to mitigate for—took 4 years to begin using the structures

Data from our very own South US 89 mitigation is now being processed by the University of Montana. Researchers there are processing wildlife-vehicle collision data, carcass information, and trail camera data collected by a broad partnership, including JHWF, WYDOT, Game and Fish, Teton Conservation District, Greater Yellowstone Coalition (GYC) and others. We hope to see preliminary results that delve into crossing structure use with and without funnel fence as well as any long-term concerns about wildlife deviating from the mitigation and crossing the highway surface at fence ends. These results will help direct any adaptive management needed to make the crossings as effective as possible.

We were just awarded seed money from the Community Foundation’s Youth Philanthropy Program (thank you Youth Philanthropists!) to launch a social media marketing campaign that will provide messaging around safe driving for wildlife in Teton County. The advertisements will include messages like local statistics and safe driving tips for locals, commuters, and visitors.

Finally, stay tuned for a JHWF-GYC-JHCA hosted speaker series that will dive into some of the wildlife-road mitigation that is in planning stages and/or has been proposed for various problem roads around the county. In our first meeting, we plan to talk more about ElectroCrete, which may be tested at fence openings along pathways adjacent to wildlife mitigation.

Thank you for your support and, as always, if you’d like to learn more please reach out to us!

Moose Day 2021 (Unofficial) Results

Moose Day 2021 (Unofficial) Results

By Frances Clark | Nature Mapping Ambassador

All 2021 Moose Day Volunteers,

Thank you for your extraordinary participation in Moose Day 2021. At this time, we have preliminary totals of 106 moose and 109 volunteers who spent 300 hours scouting! The majority of you drove (163 hrs), others skied (74 hrs), a few snowmobiled (33.5 hrs), many walked (25 hrs), and one group snowshoed (4 hrs).This is impressive! Unfortunately, as often happens on Moose Day, only half the teams saw moose (18 out of 34). This is not a reflection on your effort—you tried hard! Moose appeared most frequently along the Gros Ventre River as far east as the Darwin Ranch (14), to along the stretch around Kelly to the rotary (19). Others were seen in much less wild terrain, such as around golf courses at Teton Golf and Tennis and Teton Pines (around 20). Some were resting and feeding in neighborhoods around Wilson, Tribal Trails, and Crescent H subdivisions. Areas of deep snow in the park, downtown Jackson, the forested slopes along Fish and Fall Creek Roads had none this year. Even the Buffalo Valley, a former hotspot, had only 4 moose.

Searching for moose had its challenges. Several reported steep and high snowbanks along roads. “Berms were high so though we tried to cover the area, one never knows as it only takes a small something to hide the animals when they are lying down.” Grace Barca and her granddaughter Elly spent the morning combing the area along Fall Creek Road and up into Indian Paintbrush. “The residents said the snow was too deep on the hill.” So they looked on the flats … “We crossed three streams: Fish and Fall Creeks and the Snake and expected something in the lowlands.” Still no moose. Moose were few around Trail Creek likely because of the cross-country ski races. Notably, for only the second year, we had a team in Alta who spotted 2 moose after much driving and walking.

Jason Wilmot, biologist with the US Forest Service, led the most adventurous team on two snowmobiles east out the Gros Ventre to the Darwin Ranch. He texted: “We saw 14 moose up the Gros …. Only one dead snowmobile! Bummer. All safe though!…Beautiful up there!”…“On the hunt for a new snowmobile.” His teammate Lesley Williams, who waited two hours while the one snowmobile finished the search, was delighted to have the time alone in the solitude of wilderness. We appreciate the USFS folks for taking their days off to go search for moose.

While many people did not see moose, they did see other wildlife. The team in the north end of the park around the Jackson Lake Dam had a special treat: Kent Clements and his wife saw otter tracks around Willow Flats, and Eric Carr actually saw an otter “catch the biggest sucker fish I’ve ever seen. Huge!” Matt Fagan reported, “No moose, no traces, but we did get to watch a family of four otters moving through Willow Flats up and over dam wall…body sledding, each taking their own line down the back side. Very fun to watch. Their movements were like inchworms: doubling up in the middle then slide stretching out. Inchworm or slinky like.”

In their territory around Ditch Creek, Beverly Boynton and Ray White reported Horned Larks, mule deer, Greater Sage-Grouse, and a Great Grey Owl. Kathy McCurdy and Nancy Shea skied the stretch from Kelly to the Gros Ventre Campground and were surprised by an elk in the willows. Marjie Pettus and Brian Bilyeu scouted East Jackson and “did not see a single moose. That said, our trip was not uneventful: we saw elk (of course), bighorn sheep, 2 bald eagles, 3 deer, and no surprise, but fun 2 trumpeter swans” on the National Elk Refuge. Sue and John Ewan were down by the Snake River Sporting Club and spied a large flock of American Robins, along with Townsend’s Solitaires, and a Mourning Dove. Kathy and Jay Buchner also spotted robins north of the junction of Boyles Hill and Ely Springs Roads.

While there were no moose in their territory of the Snake River Ranch, team members observed many tracks and critters. Ben Wise saw “lots of fox tracks, maybe some ermine tracks, and a magnificent pair of bald eagles”. Jennifer Dorsey and KO Strohbehn noted tracks of martin, coyote, fox and deer, and heard Red-winged Blackbirds. Josh Metten, was able to discern “many fox tracks and holes they dug for the ‘catch.’ Vole?” Gretchen Plender reported. “Two Canada Geese flew into land in the ponds on the Shooting Star grounds! Julie (her ski partner) exclaimed, ‘Oh spring is coming!!’”

In addition, Renée Seidler, executive director of JHWF, in the area south of South Park found “two coyotes and a boat-load of swans south of the Snake River.” Mary Ellen and Bill Fausone surveyed Saddle Butte area and reported a fox, 9 deer, and “when we got home a gorgeous Great Horned Owl nesting in a tree. So is was a great day to see wildlife.”

We want to add thanks to the contributions of agencies, wildlife tour companies, and landowners. Sarah Dewey and Carson Butler of Grand Teton National Park found the 4 moose up at Buffalo Valley (fewer than in past years). Sarah also facilitated the park permit. Ben Wise of WGFD organized the team on the Snake River Ranch. Morgan Graham of Teton Conservation District surveyed Game Creek. Note, Morgan used his GIS skills to produce the Moose Day maps when Moose Day first started. Aly Courtemanch is the lead for Moose Day at WGFD. Without her, we would not have Moose Day!

We thank the owners and property managers for permission to scout Snake River Ranch, Spring Creek Ranch, Jackson Hole Winery, Jackson Hole Golf and Tennis, Teton Pines, Astoria Park Conservancy, Snake River Sporting Club, Teton Mountain Schools, and the many other private landowners. We appreciate the volunteer time of tour companies: AJ DeRosa of JH Vintage Adventures, Josh Metten of EcoTour Adventures, and Matt Fagan of Buffalo Roam Tours.

And a final note: We had participation from hearty volunteers of the Barker, Dornan, Craighead, Ewing, and Linn families—who have contributed to the understanding and appreciation of our wildlife heritage over decades. Without their commitment to the valley, we would not have so many moose and other wildlife to enjoy on Moose Day.

This is preliminary data. We will have a final report in our next Nature Mapping enews with a map of where all the moose were and comparisons to years before. However, we wanted you to be the first to know the success of Moose Day 2021.

Thank you all!

Frances Clark,
Volunteer Moose Day Coordinator

 

Neighbors to Nature: A Cache Creek Study Adds Batch Processing Function for Camera Images

Neighbors to Nature: A Cache Creek Study Adds Batch Processing Function for Camera Images

By Kate Gersh

Holy moly technology! We have exciting news to share stemming from our Neighbors to Nature: Cache Creek Study project (N2N), which is a partnership with Friends of Pathways, The Nature Conservancy-Wyoming, and the Bridger-Teton National Forest (BTNF). This project’s intent is to provide valuable wildlife, plant phenology, trail, and recreation use data to the BTNF. This data collection will inform the forthcoming BTNF Forest Plan revision process and influence the way we recreate on our trail system while coexisting with wildlife.

A component of this large-scale citizen science project is deployment of 27 game cameras throughout our local Cache Creek, Snow King and Game Creek trail system, and here is where the exciting update comes in to play. Over the course of the N2N project so far, the team has collected a whopping 719,173 total images from these game cameras! Most images contain “nothing there” because the cameras were triggered by wind, snowfall, or vegetation. We have been searching for a way to process a large quantity of camera trap images and especially, to pre-sort the images that have non-detections; thus, making the process of vetting images for wildlife identification faster and more fun for our volunteers. Thankfully, The Nature Conservancy-Wyoming recently collaborated with The Nature Conservancy-California to batch process all 719,173 game camera images through Microsoft’s Artificial Intelligence (AI) processor. The AI is trained to detect animals, people, and vehicles in camera trap images, using millions of training images from a variety of ecosystems.

Here are some example images of what detector output looks like:

In a sample of 7500 images, non-detections (aka. images with nothing there) made up 69.9%. The AI also detects people, and with a high level of confidence we can withhold images containing human subjects from further review, which is important for privacy issues (please note: AI DOES NOT identify faces). Animal detections accounted for 290 images or 3.9% of the sample. However, Microsoft’s AI does not identify animals to species; it just finds them. So, this is only a first stage and the N2N projects still needs volunteers, like yourself, to continue verifying images through the project’s Zooniverse platform. Machine learning has accelerated this process, by letting volunteers and researchers spend their time on the images that matter the most. While this streamlining of images hasn’t happened yet, we are excited to be closing in on getting the AI-processed images into Zooniverse, so soon you will be seeing far fewer “nothing here” photos!

Join the Study, Help Classify Images on Zooniverse

 We need you to help us comb through the thousands of images captured on our cameras and collect the data they provide. The information will then be analyzed by scientists at The Nature Conservancy-Wyoming. By devoting as little or as much of your time as you like, you will be providing critical data to the Bridger-Teton National Forest that will benefit both people and wildlife.

Access the Zooniverse site here.

Funny side note: It took Dr. Courtney Larson, Conservation Scientist at The Nature Conservancy-Wyoming, over a week to digitally transfer 719,173 images to the AI processor!

What Happens to Your Nature Mapping Observations?

What Happens to Your Nature Mapping Observations?

Blog author Hanna Holcomb is the 2020 Fall Americorps intern with the Jackson Hole Wildlife Foundation

By Hanna Holcomb

In 2009, local volunteers and biologists launched Nature Mapping Jackson Hole under the Meg and Bert Raynes Fund as a way to document local wildlife. Since then, more than 500 citizen scientists have logged over 70,000 observations. But as Nature Mappers log sightings of elk and bluebirds and bears (oh my), they might wonder, what happens with all of that data?

I spoke with some of the people who use Nature Mapping data, which is now run by the Wildlife Foundation, to help guide land and wildlife management decisions.

“The data that’s collected from Nature Mapping programs and all of their affiliated projects gives us a lot of information that we would have a very difficult time collecting on our own,” said Ben Wise, Wildlife Disease Biologist at Wyoming Game and Fish.

Wise pointed to Moose Day, an annual winter survey of moose on private lands in the county. Though only about 3% of land in Teton County is private, those areas are important wintering habitat for several species. But because Game and Fish conducts winter wildlife surveys from a helicopter, their usual methods aren’t possible in developed areas.

“When we’re flying over an area, oftentimes animals get up and move,” said Wise. “But if you’re trying to do that over a suburban area, you’re going to be running animals through people’s yards.”

Instead, Moose Day volunteers hike, ski, and drive, looking for moose on private land. Last year, one-hundred citizen scientists saw 127 moose.

Wise estimates that without Moose Day counts, population estimates would be 30-40% lower than they are. The data collected by Nature Mappers gives Wyoming Game and Fish a better understanding of moose population trends and distribution in the valley.

Nature Mapping data is also used to assess the natural resources of a piece of land that is proposed to be developed or conserved.

“When I wrote an environmental analysis on a green space in town, Nature Mapping data was very helpful in showing a list of species that people had seen over time using that space,” said Megan Smith, owner of EcoConnect Consulting, LLC and former Nature Mapping Coordinator. “I can go there three or four times over the course of a project, but what I see versus what hundreds of people have seen over a ten-year period is very different.”

Having long term data is also useful for the Teton County Conservation District when they are asked to assess the natural resource impacts of a proposed development on private land.

“It’s not uncommon for us to look at those development proposals and then compare Nature Mapping data to the project area as well as the vicinity,” said Morgan Graham, GIS and Wildlife Specialist at Teton County Conservation District. “And the number one thing I look for is season of use.”

For example, if Nature Mapping data shows that mule deer consistently use an area in the winter, the conservation district may emphasize the importance of reducing noise and disturbance to help mule deer conserve energy through the season.

If you’re interested in becoming a Nature Mapper, email kate@jhwildlife.org to sign up for a certification training.

And if you’re on the fence about becoming a Nature Mapper….

“The fact that you’re not an ornithologist or a trained wildlife biologist shouldn’t dissuade anybody from participating,” said Wise. “There are a lot of common animals like deer or elk, that people can report, and that’s all very valuable data for us.”

And of course…

“It’s fun,” said Graham. “And you can feel good about supporting long-term data collection.”

Counting Crows: Corvids in the Spotlight

Counting Crows: Corvids in the Spotlight

By Frances Clark

The members of the Corvid or Crow family are smart, often showy, and have a reputation. As a group they are omnivores, eating a range of food from carrion to berries to bugs. They are known for their intelligence, such as remembering locations of food stashed months previously and faces of humans who have treated them well or ill.  Each species is distinctive in appearance and voice and their behaviors reflect their habitat and social communities. As permanent residents of Jackson Hole, Corvids can be a fascinating group to observe and nature map in the coming months as many of the summer visitors move on.

Click here for a map of local Corvid sightings

The most common sightings are Common Ravens and Black-billed Magpies.  They are well known as scavengers of carrion, raiding nests for baby birds and eggs, and preying upon small mammals—in short not very appealing behavior from our human perspective. However they are also nature’s clean-up crew, as they are willing to eat most anything.

American Crows are unusual in Teton County, and perhaps overlooked due to their similarity to the larger Ravens—It can be hard to determine size against the scale of sky and mountains. Crows are smaller with less bulky beaks and a flat-ended tail when flying, vs the raven’s heavier beak and “wedge-tail” visible in flight. Crows tend to be seen more in flocks around town where they are well adapted to human spaces, while ravens are generally in pairs or family groups out in the larger landscape. The typical caw caw caw voice of crows is higher pitched that of the husky croaking sounds of ravens.

Clark’s Nutcrackers are renowned for their mutualistic relationship with white-bark pine. These gray, white, and black birds move around the West in family groups seeking areas with productive white-bark pines. At this time of the year, they will use their substantial beaks to peck and pry out pine seeds from closed cones, gulp dozens into a “sublingual pouch” and then stash them on snow-free mountainsides.  Each bird can remember 1000s of locations! Notably, males have an incubation patch to warm the eggs hatched in the heart of winter, so the females can retrieve their own stores. Over subsequent months, parents will continue to count on seeds for their survival, but also leave enough propagules to start a new generation of white-bark pines. These smart, flashy birds play a critical role in sustaining high-elevation ecosystems.

Canada Jays and Steller’s Jays are two other Corvids found mostly in our evergreen forests. Canada Jays, called “Gray Jays” until 2018, are also known as Camp Robbers and Whiskey Jacks. They are gray, plumpish birds with whitish heads touched with black. They have the smallest beaks of corvids in Jackson Hole. They fly about in bonded pairs often making a series of starling squawking sounds.

Canada Jays are boreal birds, adapted to cold evergreen forests with spruce, but here in northwest Wyoming, they are also found in mixed stands of evergreens and aspens. True to their name, they are well adapted to tough, cold conditions. Their feathers can puff up and cover both feet and bills and also allow for solar radiation to penetrate deeply for extra warmth.

Mated for life, pairs scatter-stash their food to get by over the long winter months. These Jays have glands that produce a very sticky saliva, and they use their bills to make blobs of their food and stick them under bark and lichen an on twigs and needles. Favorite foods are berries—including huckleberries, arthropods, and fungi. Like Nutcrackers, they remember 1000s of locations. They produce young in February and March when it can be -20F, using their frozen food packets to nurture both parent and offspring. They will not have a second brood even if the first fails, despite the coming of easier spring conditions.

Another unusual behavior of Canada Jays, is by late spring, the largest of the brood pushes its siblings from the parental territory and gains the benefit of pilfering the stashes of its parents and learning sites for next winter’s stores. Its siblings have to look for adoptive parents who may have lost their brood and have food reserves to share.

Canada Jays can be beguiling. When scouting for food, they glide and hop from limb to limb, tilting their heads to check out what you may have in hand. I saw several groups a week ago along the south shore of Leigh Lake, a favorite place for picnickers. Their arrival was heralded by startling cranky calls and whistles.

Steller’s Jays are more elegant in appearance, but perhaps less interesting in behavior than Canada Jays. They are found in similar habitats and eat similar food. Steller’s Jays in addition will look for white-bark pine nuts and stash single seeds, but do so much less efficiently than Clark’s Nutcrackers.  They also watch and remember where other animals store their food and pilfer as needed.

Steller’s Jays have a complex social system called “site-related dominance”. In essence, the dominant pair defends an area around its nest with the male dominant over the other males, and the female ruling over nearby females.  Other pairs are kept 5-25’ away from this central nest, whereas couples farther out are more gregarious with each other. Scientists have determined all sorts of posturing and sounds associated with this complex community.

Hawks—Red-tail, Goshawk, Cooper’s–as well as ravens are all threats to Steller’s Jays. The jays respond to their presence by “mobbing” the intruder—squawking, diving, and otherwise driving it off. This is the advantage of living in a neighborhood of jays.

While our Jays don’t migrate, in winter higher-elevation breeders can move down-slope. This is when we may see Steller’s Jays at our feeders instead of up on Teton Pass. Occasionally there may be an irruption of flocks of young birds moving about. These are all interesting movements to Nature Map.

Finally, rarely, we see the Eastern Blue Jay, a close relative of the Steller’s Jay. They both have the arched crest, iridescent blue feathers, and decorative highlights. The more boldly marked Blue Jays tend to prefer acorns typical of more eastern forests, while Steller’s seek pine seeds of our montane forests of the Rocky Mountains. Last year, Nature Mappers recorded several Blue Jays in and around Jackson.

As we all remain hunkered down during this year of covid-19, let’s get out and enjoy the Corvids. Learning their differences in identity, habitat, location, and particularly their behaviors enhances our appreciation of being in Jackson Hole. And you help our local understanding of these birds by Nature Mapping what you see!
