USU Ecologist Leading Efforts to Stop Wildlife-Vehicle Collisions

For her work in preventing wildlife-vehicle collisions, ecologist Patricia Cramer received the Denver Zoo's 2010 Conservation Award. She’s among exhibitors at USU and Swaner Preserve and EcoCenter’s Sept. 4 'Back in the Saddle’ event in Park City.

One of Cramer's remote cameras captured this mountain lion using a tunnel under Interstate 70 near Fish Lake National Forest in central Utah. It’s the first known evidence of a cougar using a culvert crossing in Utah.

After more than a decade of studying and advocating ways to prevent collisions between wildlife and vehicles, Patricia Cramer sees the tide turning. The Utah State University researcher is pleased by recent communications from state and federal highway departments asking her for input on how and where to implement wildlife crossings as they plan new projects.
 
“That’s a far cry from when I started this research as a doctoral student,” says Cramer, assistant research professor in USU’s Department of Wildland Resources. “The fact that traffic engineers are thinking about wildlife in the planning stages of road projects is a major victory.”
 
In recognition of her efforts, Cramer was selected for the Denver Zoo’s 2010 Conservation Award. She’ll formally receive the award and its accompanying $5,000 prize in an Oct. 14 ceremony.
 
Established in 1997, the annual honor recognizes the “unsung heroes of wildlife conservation.”
 
“Dr. Cramer has advanced the scientific study of wildlife crossing structures and advocates for landscape connectivity in North America,” reads the zoo’s website. “(These) crossings are essential for establishing wildlife corridors between areas of fragmented habitat.”
 
Among her current projects, Cramer is working with the Utah Department of Transportation and the Utah Division of Wildlife Resources to monitor wildlife crossing behavior at sites throughout Utah, including Interstate 80, a busy travel corridor for commuters, tourists and freight between Salt Lake City and Park City, Utah.
 
“In 2009, UDOT received federal stimulus funds to erect about three miles of fencing from Mountain Dell Reservoir to Lamb’s Canyon,” she says. “The objective was to encourage wildlife to move to areas under bridges that cross the highway at those locations.”
 
With assistance from Wildlife Protection Society founders and Park City residents Jackie and Tim Fehr, along with UDOT and UDWR personnel, Cramer installed cameras under bridges and overpasses at points on I-80 with high vehicle-animal collision rates.
 
During the previous year, portions of paved areas under these bridges were naturalized to encourage wildlife to use them. Using remote trail cameras at these locations and recording the number of animals killed on the road, Cramer and her team are helping UDOT determine if additional measures are needed to make the improvements more effective.
 
“Fencing to encourage wildlife to move to areas under bridges is a step in the right direction but large animals such deer, elk and moose occasionally breach these fences and the mitigation system also needs escape ramps to prevent them from getting trapped, separated from their young or ending up in the roadway,” she says. “With well-placed wildlife crossings, a system of secure fencing and escape ramps, animal-vehicle collisions can be reduced by 70 to 90 percent.”
 
According to the National Highway Traffic Safety Administration, about 200 Americans die in animal-vehicle accidents each year. In a recent study, the Centers for Disease Control found that one quarter of all animal-vehicle collisions result in human injury.
 
The animals fare even worse. Mangled carcasses of deer and other wildlife are a frequent sight along Utah highways. Cramer is still haunted by the grisly image of a moose crushed by a vehicle on I-80 in 2008, as the animal attempted to return to its winter feeding grounds.
 
“Combining techniques such as wildlife corridor mapping, geographic information systems modeling and considering wildlife in long-range transportation plans, we can reduce these conflicts,” she says. “We need to come up with standardized highway planning methods for wildlife and commit the funds for future wildlife crossings. These efforts pay for themselves.”
 
Cramer is among several USU researchers who will present their work at Utah State and Swaner Preserve and EcoCenter’s Sept. 4 “Back in the Saddle” equestrian-orchestral performance fundraiser at Park City’s Gray Barron Ranch.
 
The event’s featured exhibits also include a water quality monitoring and watershed education project led by Nancy Mesner, Natural Resources Extension leader and associate dean in USU’s College of Natural Resources, along with a natural resources interpretive project Mark Brunson, professor and head of USU’s Department of Environment and Society, is coordinating for the Swaner preserve.
