Be Alert Where Wildlife Roam

Since 1996, we’ve used a variety of tactics to reduce wildlife-vehicle collisions on Teton County highways. Digital Message Signs can be used to educate and alert drivers to wildlife movement on the roadways.

Slow Down for Wildlife

Fixed radar signs with violator alerts have proven effective at slowing down drivers in wildlife movement corridors.

Give Park Wildlife a Brake Campaign

The Jackson Hole Wildlife Foundation (JHWF) is introducing a new, multi-faceted campaign to address wildlife-vehicle collisions in partnership with Grand Teton National Park. As the first step, JHWF will purchase and donate to the park two “RU2 Fast” fixed radar signs with flashing violator alerts to be placed at a targeted wildlife movement corridor. Simultaneously, JHWF will invite its supporters to match its initial $20,000 contribution as National Park Service staff and JHWF discuss an array of additional solutions appropriate to site-specific issues in the park.

When the beloved grizzly bear 399’s cub was killed on a Grand Teton National Park road in June, citizens wondered aloud whether enough was being done to protect treasured wildlife. Shortly thereafter, as an extension of its existing “Give Wildlife a Brake” partnership with GTNP, JHWF and the park committed to assess vigorously every additional option designed to reduce the number of wildlife-vehicle collisions on its roads. News of a wildlife-vehicle collision that killed a grizzly bear cub on the Togwotee Pass highway on July 20 served as a grim reminder of the challenge animals face on our roadways.

Interested supporters can contribute directly to this effort. Any matching funds raised will go directly toward on-the-ground solutions in the park. As demonstrated in a similarly multi-faceted approach to reduce wildlife mortalities on WY390, an array of solutions, including fixed radar signs, variable digital message boards, speed limit reductions, education efforts, creative partnerships and mitigation tools may be more effective in combination than any one strategy.

At least 118 animals were hit on park roads last year, and 259 wildlife-vehicle collisions were recorded in Teton County outside of the park in 2015. As we implement solutions with our park partners, we will also integrate county-wide efforts such as the Safe Wildlife Crossings Initiative – a collaborative of local and regional organizations – to ensure that barriers to wildlife movement throughout Jackson Hole are minimized.

Teton County Wildlife-Vehicle Collision Database Summary Report

View the 2015 Wildlife-Vehicle Collision Database Summary Report for Teton County

We developed and house the most comprehensive wildlife-vehicle collision database for Teton County. WYDOT picks up ungulate carcasses from the roadways and they record the species, location, and date. Police record the same information for crashes that they respond to. Wyoming Game and Fish & Nature Mappers record roadkill observations when they see them.

We’ve taken all of these data from 1990-present, identified and removed duplicates, identified and removed likely errors, and analyzed roadkill hotspots for different species (elk, moose, deer, and all species together). The database includes ungulates, but Nature Mappers have also started recording some of the smaller animals and birds that normally get overlooked (red fox, squirrels, raptors, songbirds, etc.).

This database is available for use by planners, researchers, agencies, etc. (for approved purposes) at request. Please contact us!

Give Wildlife a Brake Projects

On Teton County roadways outside of Grand Teton National Park, 259 animals were killed in wildlife-vehicle collisions (WVCs) in 2015. Collisions mean injury to motorists, costly vehicle repairs, and death to an animal trying to move from one habitat to another. The good news is that simple mitigation measures can make a difference as part of a comprehensive strategy. We’re monitoring a series of mitigation measures on WY 390, where we’ve placed 3 dynamic message signs and 4 fixed radar signs, in addition to a local campaign to reduce nighttime speed limits. Collisions involving moose, deer and elk have dropped significantly in the past 3 years. For example, while 36 moose were hit and killed on WY 390 from 2010-2014, there were zero moose mortalities recorded in 2015. While it’s still too early to conclude that these measures have caused the decline in WVCs, we’re encouraged that the collective campaign appears to have had a positive impact.

RU2Fast Fixed Radar Signs

Four RU2Fast signs on WY 390 – an area of frequent wildlife movement near the vital Snake River corridor – detect driver speeds compared to the posted day/night speed limit. When the speed limit is exceeded, a flashing SLOW DOWN signal alerts drivers and if the speed limit is surpassed by more than 5 MPH, red and blue flashing lights offer a more alarming speed-check. A concerted effort to slow the speed of traffic may be contributing to a reduction of collisions on WY 390 over the past 3 years. Financial support from the Community Foundation of Jackson Hole and other generous donors has enabled us to purchase this series of fixed radar signs ($7,500 each).

Camera Traps Show Wildlife Movement in Crossing Areas

As part of a larger Safe Wildlife Crossings initiative with a host of partners (Center for Large Landscape Conservation, Greater Yellowstone Coalition, Jackson Hole Conservation Alliance, Teton Conservation District, Yellowstone to Yukon Conservation Initiative), we have placed camera traps near wildlife movement zones identified as potential sites for planned wildlife crossing structures to get a better sense of how the animals are using the areas, and which animals are most prevalent near the roadways. While data for large ungulates is fairly robust, information we find on smaller mammals and other fauna can help inform the design of future structures to aid crossing. The images also help to educate the public about the importance of removing barriers to wildlife movement while providing more support information for future transportation planning and large landscape connectivity discussions.

Dynamic Message Signs

Dynamic message signs alert drivers to slow down in critical wildlife crossing areas. Their portability allows us to work with the Wyoming Department of Transportation to relocate them periodically to ensure that the signs coincide with the most current wildlife movement patterns and potential conflict zones. With thanks to generous individual donors such as the late Uta Olson, we have been able to purchase and deploy 7 dynamic message signs ($17,500 each).

Wildlife-Vehicle Collisions Data Maps for Teton County 1990 – 2015

This is the latest data collected for wildlife-vehicles collisions in Teton County from 1990-2015. There are five maps that show data for All Species, Elk, Moose, Deer, and Non-Ungulate collisions in the Jackson Hole area. Please hover over the maps and use the arrows to scroll through the five different maps.

The full report details how many of any species has been hit relative to other species. Far more mule deer are hit than moose, for example, even if the species maps show similar volumes of hotspots. Further studies that integrate traffic volume trends, seasonal weather effects and other variables are planned.

These maps contain a kernel density with a 300 m search radius from each point. We also have maps that contain a kernel density with a 100 m search radius – enhanced precision that is useful to mitigation planning if less appealing aesthetically. Contact JHWF’s Executive Director, Jon Mobeck, if you are interested in utilizing these maps: jon@jhwildlife.org.
