"Safe Passages is a valuable sequel to Road Ecology...This new work synthesizes current and emerging mitigation techniques for diminishing the impacts of roads on terrestrial and aquatic species. Topics include the disruption of wildlife habitat connectivity, overpass and underpass crossing structures, fencing, highway design/construction, and water barriers...This work is valuable for a broad readership, but it is especially appropriate for transportation and civial engineers, conservation biologists, landscape ecologists, and wildlife managers."
