Install barrier fencing and underpasses along roads
A study in 2001–2002 along a highway in Wyoming, USA (Plumb et al. 2003) found that an underpass, in an area with roadside deer-proof fencing, was used by pronghorn Antilocapra americana. A total of 70 pronghorns passed through the underpass over 11 occasions between December and April (group size 1–57). These animals did not hesitate before crossing. An additional 19 pronghorns approached the structure but did not cross. All but two crossings took place at dusk or pre-dawn and most were in the presence of mule deer Odocoileus hemionus. A 2.4-m-high deer-proof fence was constructed in 1989 alongside 11 km of United States Highway 30. In 2001, a wildlife underpass was constructed. Underpass use was monitored using motion sensors with infrared-triggered cameras at either end from October 2001 to May 2002.
