Common toad migrations to breeding ponds are a spectacular wildlife event — but road mortality during migration represents a significant annual welfare harm.
Road mortality during toad migration represents large-scale preventable individual welfare harm. Toads killed by vehicles suffer traumatic injuries; those partially struck may survive with injuries that prevent normal function and lead to delayed death. Volunteer patrol schemes are remarkably effective at converting this mortality into successful crossings, but require annual community organisation at each affected site. Long-term solutions — toad tunnels and wildlife-permeable road design — address the problem permanently without ongoing volunteer reliance.
