In Teton County, human-wildlife coexistence is a touchy subject.<\/p>\n
A study of the impacts of recreation on wildlife in the Cache Creek area has led to chatter and controversy amongst wildlife and land managers.<\/p>\n
The paper, called \u201cNeighbors of nature: A case study of recreation-wildlife coexistence in the Greater Yellowstone Ecosystem,\u201d published in Conservation Science and Practice, used trail cameras in the Cache-Game area to study how humans and wildlife use the popular trail system. Researchers found that wildlife still use the area \u2014 and with little regard for intensity of human use. <\/p>\n
As land and wildlife managers in Jackson and across the West continue to grapple with how to protect wildlife amid increasing recreational pressure, the high-level findings of the study presented a beacon of hope to conservation-minded recreators. Several news outlets covered the study\u2019s findings and a recent op-ed in the News&Guide cited the study in support of a pathway along the Moose-Wilson Road.<\/p>\n
But the study has very specific applications, according to its authors. Researchers did not compare wildlife\u2019s present use of the area to a baseline in the area before recreation increased to today\u2019s levels. And though wildlife in the area are evidently already habituated to humans, which allows them to persist in the area, that could have negative consequences. Habituation happens when animals are repeatedly exposed to humans and lose their natural fear.<\/p>\n
\u201cWhat we\u2019re hearing is some people are taking the headline that recreation and wildlife can co-exist and saying anything goes for recreation development,\u201d said Linda Merigliano, a co-author of the paper and recently retired long-time recreation planner on the Bridger-Teton National Forest, which manages the Cache-Game area.\u201cThat is not what the study says.\u201d<\/p>\n
The study raises questions about what human-wildlife coexistence is and how it can be measured. It comes on the heels of other studies of the impact of human recreation on wildlife on the forest.<\/p>\n
A study published in March 2026 found that animals in high-use areas of the Bridger-Teton, including areas near town and the Phillip\u2019s Ridge area, are 22% less likely to flee after hearing human sounds \u2014 talking or mountain bikes, for example \u2014 than those in low-use areas of the forest. Researchers titled the paper, published in Biological Conservation, \u201cThe landscape of no worries? Increased recreation decreases the landscape of human fear in wildlife.\u201d<\/p>\n
The title was \u201ctongue in cheek,\u201d said Kathy Zeller, an ecologist at The Wilderness Society and co-author of the paper.<\/p>\n
\u201cRecreation still does have an effect upon wildlife there, even though they\u2019re more habituated to it than wildlife in more backcountry areas,\u201d Zeller said. \u201cThey\u2019re still showing those negative anti-predator behaviors, they\u2019re still fleeing, although to a lesser degree.\u201d<\/p>\n

Both studies included researchers from the Bridger-Teton, and both were conducted in anticipation of the ongoing forest plan revision.<\/p>\n
The Cache-Game study was a collaboration between the forest, The Nature Conservancy, the Jackson Hole Wildlife Foundation and Friends of Pathways.<\/p>\n

Those researchers used 1.89 million images taken by 27 trail cameras over 2.5 years in a 36 square mile area near Jackson on low, medium and high use trails in the Cache-Game and Snow King areas. Civilian scientists helped identify species identified in the camera traps. Researchers then analyzed how hiking (which included any kind of foot traffic such as running, skiing, cross-country skiing) and cycling impacted different species and how the volume of traffic impacted wildlife.<\/p>\n
Researchers did not study encounters between humans and wildlife, but rather how average weekly human use on the trails influenced wildlife use of the same area. They found that human use did not affect habitat use by deer, black bears and mountain lions. Elk were negatively impacted by human use and moose appeared to frequent the same areas as humans \u2014 but at times of day where they can avoid human presence, like early morning and late evening.<\/p>\n
The study was meant to establish a baseline to help inform future management in the study area, Courtney Larson, a conservation scientist at The Nature Conservancy and the paper\u2019s lead author.<\/p>\n
\u201cI don\u2019t think that our findings should be extrapolated across the whole region,\u201d she said. \u201cIt\u2019s a good case study of what\u2019s happening within this pocket of high use area, but I don\u2019t think we can talk about applying our findings to the Gros Ventre Wilderness.\u201d<\/p>\n
The study will help inform the forest planning process as part of the forest\u2019s monitoring plan, Merigliano said. It could help identify indicators and monitoring metrics that can be used in the area going forward.<\/p>\n
The study highlights the importance of recreation management, Merigliano said, in part because the forest does not have a laissez faire approach to recreation management in the Cache area. It\u2019s likely that wildlife still exist in Cache because of winter closures and the area\u2019s connection to other parts of the Bridger-Teton that don\u2019t see as much human use.<\/p>\n
\u201cThat area is actually embedded within a larger landscape of really wild country,\u201d Merigliano said. \u201cIf the Cache-Game area was just this island surrounded by development, we wouldn\u2019t have the critters that we have.\u201d<\/p>\n
There are some caveats to the comparison between low and high use areas in the study. Large mammals like moose and deer detected on low-use trails are still likely exposed to lots of people, due to the size of their home ranges. That means wildlife captured on low-use trails could be as used to people as those on high-use trails.<\/p>\n
\u201cMaybe they\u2019re not exposed to a ton of use right at that spot, but they\u2019re exposed to a lot of people in other places that they also use,\u201d Larson said.<\/p>\n
The study also did not track individual animals, meaning that the same animals that don\u2019t fear humans could be showing up again and again in the animals captured on camera.<\/p>\n
\u201cTrail cameras are great tools, but they\u2019re certainly not perfect,\u201d Larson said.<\/p>\n

In the other study, co-authored by Zeller, researchers set up cameras and speakers on game trails at 20 sites on the forest that see different levels of recreation. The team set up motion-triggered trail speakers to play noises that mimic the sound of human recreation and record animals\u2019 responses.<\/p>\n
Researchers also purchased anonymized cellphone location data for the forest to see how exposed wildlife in each area were to human and vehicle traffic in the 30 days preceding the sound exposure.<\/p>\n
Researchers found that wildlife exposed to heavy human use were 22% less likely to flee than those in areas that humans visit infrequently. Wildlife in high-use areas spent slightly more time being vigilant than those in the lowest use areas.<\/p>\n
The study is a follow-up on an earlier study published by the team that found that, in backcountry areas, animals are generally 1.5 times less likely to inhabit places where they have heard sounds of human recreation in the last week.<\/p>\n
\u201cThere was something about the way these animals arrange their lives when we are not present that changed when we were there,\u201d said Jesse Barber, a sensory ecologist at the American Museum of Natural History and Boise State University.<\/p>\n
After analyzing the data, the team built a map, using the cellphone location data, to show how likely animals are to flee on various parts of the forest. They are working on a follow-up paper to study how long it takes for wildlife to habituate to recreating humans.<\/p>\n

Researchers studying recreation on the Bridger-Teton National Forest found that animals in areas with heavier recreation use are less likely to flee after hearing mock human noises. With their findings, they used anonymized cellphone data to create this map of how likely animals were to flee across the forest, with red being more skittish and yellow being less.<\/p>\n
\u201dThe landscape of no worries? Increased recreation exposure decreases the landscape of human fear in wildlife\u201d<\/p>\n
Many questions about habituation remain unanswered.<\/p>\n
Researchers are unsure whether wildlife become used to human presence, or whether less tolerant individuals leave and individuals predisposed to being comfortable around humans remain.<\/p>\n
\u201cAre some members of the species leaving, and we\u2019re not noticing that because they are replaced by more tolerant individuals?\u201d said Barber, the sensory ecologist. \u201cThat\u2019s been shown in other systems.\u201d<\/p>\n
There could be consequences to pushing out more fearful individuals, including removing them from the gene pool, Barber said<\/p>\n
The alternate scenario, in which animals with different human tolerances habituate, could also have upsides and downsides.<\/p>\n
Habituation, Barber said, is not necessarily \u201ca big negative.\u201d It is \u201cpotentially useful,\u201d because it allows animals to access habitat that would otherwise be lost to them, said Mark Ditmer, a quantitative ecologist at the U.S. Forest Service\u2019s Rocky Mountain Research Station and lead author of the sound study. That means habituation may help support a larger population of a given species.<\/p>\n
But habituation can lead to conflict, as it does with bears and sometimes elk, Ditmer said. Habituated wildlife could less natural fear and could be more likely to be predated, Barber said.<\/p>\n
\u201cIn general, the more wild-acting an animal is, the better it\u2019s going to be able to handle real-world threats,\u201d Ditmer said.<\/p>\n
Even if wildlife persist in a place, they could still be experiencing a spike in stress hormones in response to seeing humans, Larson said. With hundreds of people going by every day, chronic stress could lead to invisible, negative health impacts.<\/p>\n
The potential consequences of habituation beg the question of what \u201ccoexistence\u201d is and whether it means something more than \u201cco-occurence.\u201d The Bridger-Teton defines the former term as the ability for wildlife to live and humans to recreate in the same place.<\/p>\n
\u201cI think we hemmed and hawed a little bit about putting that word in the title of our paper, because we didn\u2019t want it to be misinterpreted,\u201d Larson said. \u201cI\u2019m not sure if it was a good decision.\u201d<\/p>\n
The studies also raise a philosophical question of what it means for wildlife to be \u201cunimpaired,\u201d Barber said.<\/p>\n
\u201cAn unimpaired ecological system is a place where animals can perform behaviors the way they would in a natural system,\u201d he said. \u201cThat doesn\u2019t mean no people. But it probably doesn\u2019t mean a mountain biking system right outside of Jackson.\u201d<\/p>\n
Researchers from both studies found that keeping recreation concentrated in dense areas would benefit wildlife.<\/p>\n
\u201cI think our study really speaks to the value of having these dense pockets that are designated for recreation, which have a lot of wildlife value, but then also keeping some areas free of recreation that are really meant for wildlife,\u201d Larson said.<\/p>\n","protected":false},"excerpt":{"rendered":"In Teton County, human-wildlife coexistence is a touchy subject.
