| 摘要： | Efforts at concerted and purposeful activity towards linking transportation services and ecological services into a context-sensitive planning, construction, and monitoring process have increased dramatically during the past few years. As a result, once piecemeal and haphazard mitigation approaches have been replaced with much more integrated efforts that have provided useful data to highway planners and engineers. The research team for this project, NCHRP 25-27, Evaluation of the Use and Effectiveness of Wildlife Crossings, was charged to provide guidance in the form of clearly written guidelines for the selection, configuration, and location of crossing types, as well as suggestions for the monitoring and evaluation of crossing effectiveness, and the maintenance of crossings. Providing guidance on the use and effectiveness of wildlife crossings to mitigate habitat fragmentation and reduce the number of wildlife vehicle collisions involves thinking in a large-scale, context-sensitive framework that is based on sound ecological principles. Landscape permeability (i.e., the ability for species to move freely across the landscape) is the guiding principle for this work, and the foundation for effective mitigation. The goal for this research project was to develop sound guidelines based on the premise that understanding and establishing landscape permeability leads to effective landscape connectivity and the restoration of ecosystem integrity. At the same time, the guidelines should allow for efficient and effective transportation infrastructure mitigation in a cost-effective, economic manner. The guidelines were developed in the form of a final report and a web-based interactive decision guide. |
