Our annual wildlife-vehicle collision (WVC) summary report collects information from the Wyoming Department of Transportation, Wyoming Game & Fish Department, and citizen observations in order to provide the most comprehensive overview of wildlife-vehicle collisions in Teton County.
The last reporting year included 181 recorded WVCs, nearly 50% lower than the previous year. This continues a trend of sharp peaks and valleys corresponding largely with winter severity. The relatively mild winter (and more navigable snowpack) in 2017-2018, combined with the effects of a severe winter (and corresponding WVC spike) in 2016-2017, partly explains the sharp decrease in WVCs from May 2017 through April 2018. Winter 2016-2017’s high mule deer mortality rate also likely led to localized population declines, which could have contributed to the WVC decline, which is almost entirely due to fewer mule deer WVCs: dropping from 265 to 105.
Of note, however, is that elk casualties (49) did not decline, nor did moose (20). Wyoming Highway 22 showed a sharp rise in moose WVCs.
The 2017-2018 report was delayed to ensure data integrity as public agency databases were combined. The 2018-2019 report (May 2018-April 2019) will be available in the fall of 2019.
Tips for Creating Wildlife Friendlier Fences
- Use natural vegetation in the form of trees, bushes and gardens to delineate property boundary instead of a fence.
- If the fence is strictly aesthetic, try a low post and rail fence that wildlife can easily jump.
- Consider fencing only a portion of your property as a child’s play area, dog run or to protect a garden from wildlife.
- The height of the toprail should be no higher than 38-40 inches.
- If wire is desired, only use smooth wire and make sure the bottom wire is at least 16 inches off the ground to allow young animals and antelope to pass under.
- Choose a post and rail fence over a buck n’ rail fence, which is generally too tall and too wide for wildlife to navigate.
- Use fencing to enhance a wildlife corridor by using different kinds of fence for different purposes.

The Teton County Wildlife Crossings Master Plan Action Summary reflects the recommendations of the advisory committee at present. Most of the committee members have been active in conversations about wildlife crossings for several years. The committee is comprised of biologists, county engineers and planners, wildlife experts and advocates who are deeply invested in ensuring that the Master Plan is a usable document for future wildlife-vehicle collision mitigation. This group worked to provide local knowledge of locations, the social landscape, and our assessment of future feasibility to develop recommendations. Ongoing discussions with partners may result in adjustments to the priorities suggested herein. This summary document does not assume any future highway improvement projects, although future project potential and integration opportunities are considered. Also, while locations within Grand Teton National Park may benefit from mitigation consideration, the national park conducts its own wildlife-vehicle mitigation studies and subsequently was not included in this assessment.
