Special Seminar: Room 471 Cramer Hall on the Portland State University campus

Abstract: Across the globe wildlife crossings are becoming an accepted mitigation to adapt roads for wildlife movement. With over 800 crossings in the U.S., there are efforts to create new wildlife crossings and retrofit existing structures for wildlife in every state. Science plays a critical role in designing wildlife crossings. Research can show how well different bridge, culvert, and fence designs work at passing wildlife safely under the road, and areas that need adaptive management. This talk will give viewers an overview of wildlife crossings in North America from the speaker's National Academies study, and how research in the western U.S. is helping departments of transportation design, place, and retrofit wildlife crossings that allow multiple species to move under and over roads safely. Dr. Cramer will speak about the ongoing and past wildlife and road studies she has conducted in Utah, Montana, Idaho, Washington, and soon Oregon.
