• Abstract:
  Pronghorn (Antilocapra americana) movements were investigated with Global Position System (GPS) ; telemetry from 2007 to 2008 along a 28-mile stretch of U.S. Highway 89 in northern Arizona to develop ; strategies to enhance permeability with future highway reconstruction. Research objectives were to: ; • Assess pronghorn movement patterns and distribution and determine highway permeability. ; • Investigate the relationships of pronghorn distribution patterns to vehicular traffic volume. ; • Assess the influence of fencing on pronghorn highway crossing patterns and permeability. ; • Investigate pronghorn-vehicle collision patterns. ; • Develop recommendations to enhance pronghorn highway permeability. ; The team tracked 37 pronghorn (20 females, 17 males) with GPS receiver collars. Of 118,181 GPS fixes, ; 1,125 occurred within 0.15 mile of US 89, and 3,794 occurred within 0.30 mile. Only one pronghorn crossed ; US 89 during the two years of tracking. The mean passage rate was a negligible 0.006 crossings/approach. ; No collisions with vehicles were recorded during the study. In total, 5,035 weighted pronghorn approaches, ; number of animals/segment, and five other criteria were used to rate 0.6-mile highway segments for ; suitability as passage structure locations. The team recommended 3.2-mile spacing between passage ; structures and three sites for passage structures integrated with fencing and noise reduction measures.
