Wildlife Welfare

Wild Otter Welfare and River Quality

Otter welfare in UK waterways is closely linked to river water quality, food availability, and road infrastructure.

Key Facts

Otter populations have recovered substantially in the UK since the 1970s following pesticide bans
Road casualties remain the leading cause of human-related otter mortality
Pollution events can cause acute mass mortality in otter populations through prey depletion
Otters require extensive territories with abundant fish populations
Illegal persecution, though reduced, still occurs in some river catchments

Welfare Considerations

Otter welfare is inextricably linked to the health of UK river ecosystems. Protecting individual otter welfare requires addressing systemic river quality issues, road crossing infrastructure, and ongoing illegal persecution. The recovery of UK otter populations demonstrates that sustained, evidence-based conservation can deliver genuine wildlife welfare improvements.

What You Can Do

Support river clean-up and rewilding initiatives that benefit otter habitats
Advocate for wildlife-friendly road design including otter underpasses in river crossing locations
Report suspected illegal persecution of otters to the relevant wildlife crime authorities
