Snapping Turtle Welfare and Road Mortality

Common snapping turtles are ecologically vital freshwater predators facing significant mortality from road crossings, particularly during nesting season.

Key Facts

Female snapping turtles can travel up to 1.5 km to find suitable nesting sites
Road crossing mortality is a significant population-level threat
They can live over 40 years and take 12-20 years to reach reproductive age
Snapping turtles play important roles in aquatic ecosystems as scavengers and predators

Welfare Considerations

Snapping turtles are slow to mature and reproduce, meaning adult mortality has disproportionate population impacts. Road mortality peaks in late spring through summer when females seek nesting sites. Turtles struck by vehicles suffer severe trauma. Handling for relocation requires care as they can cause serious bites. Road mitigation measures including culverts with drift fencing have been shown to reduce mortality. Nest predation by raccoons and skunks, often elevated near human areas, also reduces recruitment.

What You Can Do

Help turtles cross roads safely by moving them in the direction they were heading
Never relocate turtles far from where found as they home strongly to their territory
Build or advocate for wildlife crossing structures on roads near wetlands
Participate in local turtle monitoring programs
Reduce predator-attracting waste near natural areas to limit nest predation
