Enhancing Existing Isolated Underpasses with Fencing Reduces Wildlife Crashes and Connects Habitat 2021, Human–Wildlife Interactions

...Our study found that the addition of wildlife fencing to certain existing isolated underpasses can be a highly cost-effective means of increasing driver safety and enhancing habitat connectivity for wildlife. The benefits from crash reduction exceeded the fencing costs in 1.8 years, and fencing resulted in an average saving of >$2.3 million per site over the 25-year lifetime of the fencing. The results add to the growing body of knowledge about effective ways we can use existing infrastructure to connect wildlife habitat and increase driver safety...

A sound deterrent prevented deer intrusions at the intersection of a river and fence T Honda - Mammal Study, 2019

...Previous studies reported that sound deterrents were ineffective, but this study revealed efficacy of the sound deterrent; this disparity could be due to the use of an attractant, since most studies employed food to test deterrent effectiveness. The short-term (four-week) tests demonstrated the effectiveness of the sonic device; however, long-term tests revealed that the efficacy declined with long-term usage (habituation effect). Use of the device should be limited, i.e., for no longer than one month...

Electronic Deer Warning System December, 2016 Zhuo, Lu. CA San Luis Obispo - 2016

... The primary means of detecting a moving vehicle is via seismic vibration. It is known that deer can hear ultrasonic tones up to 30 KHz (inaudible to humans), so the system will create these sounds with piezoelectric buzzers. The firmware was designed to be simple to understand, with helpful abstractions provided to future programmers. This is important so that researchers are not hampered by the code and understanding the system, and can instead focus on research and parsing data. Additionally, the hardware circuitry involved with data collection and power management was created to be as power-efficient as possible so that the system will require as little maintenance as possible...

Effectiveness of short sections of wildlife fencing and crossing structures along highways in reducing wildlife–vehicle collisions and providing safe crossing …MP Huijser, ER Fairbank, W Camel-Means, J Graham… - Biological Conservation, 2016

... If the primary success parameter is to improve highway safety for humans by reducing collisions with large ungulates, the data suggest fence lengths of at least 5 km. While longer fence lengths do not necessarily guarantee higher wildlife use of underpasses as use varies greatly between locations, wildlife fencing can still improve wildlife use of an individual underpass...


Could Cattle Guards Augmented with Electrified Pavement Prevent Mule Deer and Elk Access to Highways? [PDF] JP Flower, PC Cramer, UT Logan - 2015 Utah

... Based on strong results from the feeding exclosure trial, electrified pavement appears to have potential as an effective tool to reduce ungulate access to roadways when deployed at wider dimensions. Moreover, the material may offer a mitigation option for locations unsuitable for double cattle guards and wildlife guards, such as at end points in wildlife exclusion fencing and/or across roads with annual average daily traffic of greater than 500 vehicles...


Road and traffic factors correlated to wildlife–vehicle collisions in Galicia (Spain) E Valero, J Picos, X Álvarez - Wildlife Research, 2016

... Our results showed that the daily traffic volume, the width of the road, the number of lanes and speed limit affect whether a particular road marker has a high or low density of WVC... high WVC is frequently characterised by wider lanes and shoulders, as well as gentler slopes, whereas in the sections with narrower roads and a shorter curvature radius, there are some conditions (low visibility and speed reduction) that reduce the probability of having an accident with ungulates. However, the speed at which it is possible to drive on a given road section is closely related to the occurrence of WVC. These findings emphasise the importance of including mitigation measures in the decision-making when planning and designing infrastructure...


Roadside Activity and Behavior of White-Tailed Deer (Odocoileus Virginianus) and Other Wildlife Near Unfenced Underpasses BM Donaldson, YJ Kweon, LN Lloyd - 2016

... Highway crossing attempts by deer resulted in 7.5 DVCs per year on the 1-mile highway segments adjacent to the unfenced underpasses. The findings support the installation of fencing along the roadside adjacent to existing underpasses used by deer. After the planned fence installation, the post-mitigation monitoring study may show that this low-cost form of mitigation could have a substantial impact on drivers and wildlife, particularly if implemented on a large scale...

An Evaluation of Roadside Activity and Behavior of Deer and Black Bear to Determine Mitigation Strategies for Animal-Vehicle Collisions [PDF] BM Donaldson, YJ Kweon, LN Lloyd - 2015 Virginia

... Study recommendations include (1) the installation of fencing along the roadside adjacent to existing large underpasses, and (2) an animal advisory message on the dynamic message signs along I-64 in the Afton Mountain area. Messages should be displayed from dusk through dawn from October through November (to correspond with periods of higher deer activity and DVCs). Fencing both sides of just one underpass is expected to result in a savings in costs associated with DVCs of $501,473 over its service life. ..

Context-dependent effects on spatial variation in deer-vehicle collisions AP Clevenger, M Barrueto, KE Gunson, FM Caryl… - Ecosphere, 2015

... Distance to water was an important predictor of WVCs in three of the five study areas, while other variables had modest importance in only two of the five study areas. Thus, lack of generality in factors predicting WVCs may have less to do with methodological or taxonomic differences among study areas than the large-scale, biophysical context within which the data were collected ...

...Deer rarely find their way past the security fence and onto the airfield at HIO, and do not need to be dispersed if they are outside of the airfield security fence. If there is a need to remove deer from within the security fence, Airport staff may gently coax them to a place where they can exit the airfield or they will be lethally removed following the Port’s Oregon Department of Fish & Wildlife permit...


How does variation in winter weather affect deer-vehicle collision rates?

DD Olson, JA Bissonette, PC Cramer, KD Bunnell…Utah, - Wildlife Biology, 2015

...We found that precipitation decreased 50% and snow depth decreased 48% between winters. In response, deer used habitats that were 16% higher in elevation and that were 213% farther from roads with high traffic volumes. Consequently, crossing rates also decreased as much as 96% on roads with high traffic volumes. Reduced crossing rates were likely responsible for much of the 75% decrease in deer—vehicle collisions that occurred during the second winter....

Underreporting of wildlife-vehicle collisions does not hinder predictive models for large ungulates NP Snow, WF Porter, DM Williams - Biological Conservation, 2015

... Our objective was to test the sensitivity of WVC studies to underreporting using 2 species of large ungulates that experience substantial incidences of collisions but exist in different environmental settings: white-tailed deer (Odocoileus virginianus) in agricultural-dominated central Illinois and moose (Alces alces) in forest-dominated western Maine, USA... Prediction estimates for both species were also reliable until high rates of underreporting occurred (⩾75%). These findings suggest that predictive models generate reliable estimates about WVCs with large ungulates unless underreporting is severe; possibly because they occur in non-random patterns (i.e., hotspots) and variability in their environment influences is low ...
