Wild Otter Conservation and Welfare

European otter populations have recovered significantly since their nadir in the 1970s, but road mortality and water quality remain welfare and conservation concerns.

Key Facts

UK otter populations recovered from near-extinction after organochlorine pesticide bans
Road mortality is now the leading cause of otter death, particularly young dispersing males
Otters require 20-40 km of river territory with clean water and adequate fish prey
Otter holts (dens) require bankside vegetation that has declined in many rivers
Mink control has benefited otter recovery by reducing competition in some areas

Welfare Considerations

Individual otters killed on roads die traumatic deaths that are preventable through road infrastructure modifications including underpasses at known crossing points. River quality improvements that support fish populations also prevent individual otter starvation welfare impacts.

What You Can Do

Support otter crossing projects on major roads near river systems
Donate to river restoration programs improving water quality and bankside habitat
Report otter sightings and road casualties to local wildlife trusts
