![]() We found no detectable effect on road-kill of crossing structures without fencing. Fences, with or without crossing structures, reduce road-kill by 54%. Overall, mitigation measures reduce road-kill by 40% compared to controls. ![]() ![]() We conducted a meta-analysis using data from 50 studies that quantified the relationship between road-kill and a mitigation measure designed to reduce road-kill. For road planners, deciding on what mitigation method to use has been problematic because there is little good information about the relative effectiveness of these measures in reducing road-kill, and the costs of these measures vary greatly. To address this problem there are more than forty types of road mitigation measures available that aim to reduce wildlife mortality on roads ( road-kill). ![]() Road traffic kills hundreds of millions of animals every year, posing a critical threat to the populations of many species.

A Meta-Analysis.
