WILDLIFE CROSSINGS IN NORTH AMERICA: THE STATE OF THE SCIENCE AND PRACTICE.

WILDLIFE CROSSINGS IN NORTH AMERICA: THE STATE OF THE SCIENCE AND PRACTICE. By Dr. P. C. Cramer, Research Associate, and Dr. John A. Bissonette, Research Scientist, USGS Utah Coop Unit, Utah State University. In this paper we present results from a telephone survey as part of a National Cooperative Highway Research Program (NCHRP) project, Evaluation of the Use and Effectiveness of Wildlife Crossings (NCHRP 25-27). Specifically, we present a summary of North American efforts to mitigate road effects for wildlife. We stress the need to provide multiple wildlife passages along transportation corridors to begin to accommodate the movement of the full complement of species in an area.
