Wild River Otter Road Casualty Hotspots

Road casualties are a significant cause of otter mortality in the UK, particularly at river crossing points. Targeted infrastructure interventions can reduce deaths.

Key Facts

Road casualties are estimated to cause 20-30% of otter mortality in some areas
Otters cross roads at bridges where they prefer to travel under the road via the river
Unsuitable bridge design forces otters onto the road surface
Ledges under bridges providing dry passage at high water significantly reduce crossings
Camera traps at known hotspots help identify and prioritise interventions

Welfare Considerations

Otter road casualties cause acute suffering and death. Vehicle strikes often result in severe injuries before death. Targeting known hotspots with habitat management and infrastructure improvements - including dry ledges under bridges - offers cost-effective welfare and conservation benefits.
