Wild River Otter UK Recovery 2026

The continuing recovery of river otters in the UK following pesticide bans, and current welfare challenges including road mortality and pollution.

Key Facts

River otter populations have recovered from near-extinction to most UK river systems
Organochlorine pesticide bans in the 1970s-80s were the key driver of recovery
Road mortality remains significant, particularly where roads cross rivers near the sea
Pollution events including agricultural run-off cause acute otter welfare harm
Otter distribution surveys in 2021-22 showed presence in over 95% of surveyed sites

Welfare Considerations

Otter recovery is a landmark UK conservation success. Individual otters still face welfare threats from road mortality and pollution events. Maintaining clean rivers and otter-safe road infrastructure is essential to sustain recovery.
