Otter: Recovery and Ongoing Welfare Challenges

Otters have made a remarkable recovery following pollution controls but still face significant welfare threats.

Key Facts

UK otter populations collapsed in the 1960s following organochlorine pesticide use
Recovery followed restrictions on these chemicals from the 1970s onwards
Otters are now found in all English and Welsh river catchments
They eat mainly fish requiring rivers with good fish populations
Road mortality is now the leading cause of otter death in England

Welfare Considerations

Otters face ongoing welfare challenges despite their recovery. Roads crossing rivers cause significant mortality particularly for young dispersing animals. Fish farm raid attempts lead to persecution. Water pollution and disease remain threats. Entanglement in fish traps and eel fyke nets causes drowning deaths. Climate-driven flooding can destroy holts with cubs.

What You Can Do

Support the installation of otter ledges under bridges to reduce road crossings
Advocate for otter-proof eel and fish trap design
Ensure fish traps always include otter guards as legally required
Report road-killed otters to local Wildlife Trusts for post-mortem analysis
Support river restoration projects that improve fish populations and habitat
