Roadkill Reduction — Infrastructure and Speed Management

Road vehicle collisions kill millions of wild animals annually across Europe and North America, representing one of the largest sources of human-caused wildlife mortality.

Key Facts

An estimated 1.5 billion vertebrates are killed by vehicles annually in Europe alone
In the US, deer vehicle collisions kill approximately 1.5 million deer per year
Badger roadkill represents the largest annual adult mortality cause in many UK populations
Wildlife crossing underpasses reduce target species mortality by 80-90% where installed
Speed reduction from 100km/h to 80km/h reduces collision probability by approximately 50%

Welfare Considerations

Vehicle collisions cause traumatic injury and death to billions of wild animals annually. Animals struck by vehicles experience crushing force, multiple fractures, and internal organ damage. Many survive initial impact and die slowly from injuries before being found. Road mortality is not random — it concentrates on wildlife movement corridors and seasonal migration routes. The welfare case for road mitigation infrastructure (crossings, underpasses, fencing to guide animals to crossing points) is strong: studies show 80-90% reductions in target species mortality at instrumented crossing sites. Speed reduction in wildlife-heavy zones is the single cheapest intervention with the largest welfare benefit.

What You Can Do

Slow down in dusk and dawn hours in wildlife-active zones
Support wildlife crossing funding through advocacy and donations
Report wildlife collision injuries to local wildlife rehabilitators
Advocate for reduced speed limits in seasonal wildlife movement zones
Support badger and deer fencing programs along highways in high-mortality areas
