Abstract
Transportation networks fragment the natural landscape and create barriers that interfere with animals’ ability to move across landscapes to meet biological needs such as finding food, water, cover, and dispersing to new areas to secure access to mates to increase genetic diversity. Mortality of wildlife due to collisions with vehicles can have direct impacts at the population level. For many imperiled or sensitive species, the impacts of roads may be uncertain. The U.S. Fish and Wildlife Service Recovery Outline for the jaguar (Panthera onca) identified the need to assess the impact of roads on jaguars and measures to enable these rare carnivores to safely cross roads for the recovery of this species. This document addresses these measures by offering recommendations drawn from a growing body of literature and case studies on techniques that have high potential to facilitate safe movements of jaguar across roads at the northern extent of their historical range in Mexico and in the southwest United States (i.e., the Northwestern Recovery Unit).
