Wildlife Highway Crossing Welfare Benefits

Wildlife road crossing infrastructure - underpasses, overpasses, and culverts - dramatically reduces road mortality and allows natural animal movement, providing direct individual welfare benefits.

Key Facts

Road mortality kills an estimated 100 million vertebrates annually in Europe
Wildlife crossings reduce road mortality for target species by 50-90% in evaluated studies
The Banff wildlife overpasses in Canada have been used by bears, wolves, and elk
Toad tunnels with drift fences reduce toad road mortality by up to 95%
Bat flyway structures maintain commuting corridors under roads that break flight lines
The Liberty Canyon wildlife crossing in California will link isolated mountain lion populations

Welfare Considerations

Wildlife crossing infrastructure provides direct, measurable welfare benefits by preventing traumatic death and injury from vehicle collisions. Animals killed by vehicles experience acute trauma, often not immediately fatal. Surviving injured animals experience prolonged suffering from wounds, fractures, and shock. Crossings that allow natural movement also prevent the chronic stress of animals trapped in habitat fragments unable to find mates or resources. The welfare return on crossing investment is very high - each structure prevents thousands of individual welfare harms over its lifespan. Consumer and citizen advocacy for crossing infrastructure in planning decisions is one of the most impactful welfare actions available.
