Evaluation of Measures to Minimize Wildlife-Vehicle Collisions and Maintain Permeability Across Highways: Arizona Route 260

摘要: The authors conducted wildlife-highway relationships research from 2002-2006 along a 17-mile stretch of State Route 260 in Arizona which is being reconstructed five phases with 11 wildlife underpasses and six bridges. Reconstruction phasing allowed the to use before-after-control experimental approach their research. objectives were: 1) assess compare underpasses; 2) evaluate highway permeability movements among reconstruction classes; 3) characterize wildife-vehicle collision patterns changes reconstruction; 4) traffic volume vehicle collisions, elk crossing patterns, 5) role that ungulate-proof fencing plays underpasses, permeability; 6) provide ongoing implementation guidance. used video surveillance at they recorded 8,455 animals different species; 5,560 these (65.8%) crossed through underpass. employed global positioning system telemetry across SR 260, 65 fitted receiver collars. Elk 5,749 times. on (0.43 crossings/approach) was half control sections. Permeability increased 60% after erected section. Effective monitoring adaptive management yielded benefits safety alike.
