| 摘要： | The research team assessed elk (Cervus elaphus), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) movements and vehicle collision patterns from 2007 through 2009 along a 57 mi stretch of State Route (SR) 64 to develop strategies to improve highway safety and wildlife permeability. This study followed the SR 64 2006 Final Wildlife Accident Reduction Study that recommended nine wildlife passage structures and further monitoring to determine the best locations for passage structures and fencing. Research objectives were to: (1) Assess wildlife movements, highway crossing patterns, and permeability across SR 64. (2) Assess relationships of wildlife crossings and distribution to vehicular traffic volume. (3) Investigate wildlife-vehicle collision spatial and temporal incidence and patterns. (4) Determine use of Cataract Canyon Bridge by wildlife for below-grade passage. (5) Develop recommendations to enhance highway safety and wildlife permeability. The team tracked 23 elk, 11 deer, and 15 pronghorn with Global Positioning System (GPS) receiver collars, yielding mean passage rates of 0.44, 0.54, and 0.004 crossings/approach, respectively. In total, 167 wildlife-vehicle collisions were analyzed. Traffic volume influenced permeability and wildlife-vehicle collision patterns. The team recommended 11 passage structures, including Cataract Canyon Bridge, which had modest current wildlife use, along with wildlife fencing to reduce collisions and promote permeability for elk, deer, and pronghorn. |
