Mitigating Transportation's Disruption of Ecosystems

State departments of transportation need guidance on the use and effectiveness of wildlife crossings to mitigate habitat fragmentation and to reduce the number of animal-vehicle collisions on roadways. Under NCHRP Project 25-27, Evaluation of the Use and Effectiveness of Wildlife Crossings, a research team at Utah State University is developing guidelines for the selection, configuration, and location of crossing types, as well as suggestions for the monitoring, evaluation, and maintenance of crossings. Guidance on the use of wildlife crossings to mitigate habitat fragmentation and to reduce the number of animal-vehicle collisions will rely on a large-scale, context-sensitive framework and on sound ecological principles. The guidelines will aim for landscape permeability--effective connectivity that restores an ecosystem's integrity. At the same time, the guidelines must allow for cost-effective mitigation of the effects of transportation infrastructure.
