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.


A Wyoming Landowner’s Handbook to Fences & Wildlife

A Wyoming Landowner’s Handbook to Fences & Wildlife

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.

Teton County Wildlife Crossings Master Plan Action Summary

Teton County Wildlife Crossings Master Plan Action Summary

Read the Master Plan here

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.

Tips for Reducing Human to Bear Conflicts

  • CONTACT TETON COUNTY TO FIND OUT IF YOU LIVE IN A BEAR CONFLICT PRIORITY AREA. Special garbage-storage regulations may apply to where you live.
  • Keep garbage containers inside a secure building until the morning of pickup.
  • Store recyclable containers, such as pop cans, indoors; the sweet smells attract bears.
  • Store especially smelly garbage, such as meat or fish scraps, in a freezer until it can be taken to a refuse site.
  • Do not leave food from barbeques and picnics outdoors, especially overnight; coolers are not bear-proof.
  • Replace hummingbird feeders with hanging flower baskets which are also attractive to hummingbirds.
  • Store pet food inside and feed pets inside.
  • Clean and store barbeque grills after each use, put them in a secure shed or garage.
  • Pick fruit from trees as soon as its ripe and collect fallen fruit immediately
  • Do not put out feed for wildlife (corn, oats, pellets, three-way, nor molasses blocks). It is not only harmful to wildlife, it is prohibited by a Teton County Ordinance.

Bear Wise Bird Feeders

Forty percent (40%) of human/bear conflicts in Teton County are related to bird feeders. For a bear, bird seed is a tasty high-calorie, low-effort snack. Unfortunately, bears who become conditioned to getting food from bird feeders often get into other trouble around people’s homes with garbage, pet food, animal feed, fruit trees, or gardens.

Land Development Regulations in Teton County require that from April 1 – November 30, all bird feeders (including hummingbird) must be hung at least 10 feet high and four feet away from any supporting structure and have a catch pan for seed. JHWF is working to educate people about the existence of this regulation and provide information on other ways to enjoy birds around your home.
