Wildlife Road Mortality: Scale, Welfare Impact, and Solutions

Roads kill hundreds of millions of animals annually worldwide, representing one of the largest sources of human-caused wildlife mortality with widespread individual welfare impacts.

Key Facts

An estimated 1 million vertebrates are killed on US roads every day
Hedgehog road mortality contributes significantly to UK population decline
Mitigation measures including wildlife crossings can reduce mortality by 85%
Road mortality disproportionately affects rare and recovering wildlife populations
Light pollution from roads disrupts nocturnal wildlife navigation and behavior

Welfare Considerations

Road-killed animals frequently experience prolonged suffering before death from impact injuries. Survivors of vehicle strikes often sustain internal injuries, fractures, and brain trauma that result in slow death or permanent disability. The welfare impact on individual animals is severe, and the scale of mortality makes this a significant conservation and welfare concern.

What You Can Do

Drive at reduced speeds through wildlife corridors particularly at dawn and dusk
Support funding for wildlife crossing infrastructure on major roads
Participate in wildlife road mortality citizen science monitoring
Report road-killed animals to local wildlife authorities for population monitoring
Advocate for wildlife-sensitive road design in planning consultations
