Wildlife Behavior Responds to Traffic Noise

Anthropogenic noise is a widespread and persistent disturbance of wildlife in areas adjacent to urban areas and near roads. If traffic noise inhibits wildlife from approaching wildlife crossings, they may be less useful to all wildlife, and unusable to certain more sensitive species. We investigated traffic noise impacts on wildlife behavior near crossing structures and found species and temporal variations. If widespread, these could reduce the effectiveness of wildlife crossing structures.

CA Roadkill Hotspots Report 2021

Wildlife-vehicle collisions (WVC) can result in death of the animal and vehicle damage and injury to the driver and passengers. This report updates previous analyses of economic and ecological impacts of "roadkill", another term for WVC (https://roadecology.ucdavis.edu/resources/california-wildlife-vehicle-collision-hotspots-2021). According to our analyses, California has incurred 1 to 2 billion dollars in costs related to WVC over the last 5 years.

Ireland Develop Measures to Reduce Barn Owl Mortality on Roads

Bird scientists and transportation specialists in Ireland have developed a series of measures to reduce impacts to barn owls. As in California and elsewhere, barn owls in Ireland forage along roadsides, putting them at risk of collisions and drivers at risk from swerving to avoid a collision. These new measures were designed to reduce collisions with barn owls.
