  1. Install wildlife warning reflectors along roads

    A replicated, controlled study in 2000–2003 along 10 highways in Virginia, USA (Cottrell 2003) found that warning reflectors did not reduce collisions between vehicles and deer Odocoileus sp. There was a similar rate of deer road casualties on sections with reflectors (4.6/mile/year) compared to sections without reflectors (4.8/mile/year). Deer warning reflectors (red) were installed on posts along 0.4–2.3-km sections of 10 highways (2–4 lane) from October 2000 to May 2002. Reflector sites and adjacent sites without reflectors were each monitored for 6–28 months. Deer road-kills data were collated by officials from the state Department of Transportation.
