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.
