Wildlife Welfare

Otter UK Habitat and River Welfare

Otter populations in the UK have recovered significantly after near extinction, but continue to face threats from roads, pollution and prey availability.

Key Facts

UK otter populations declined dramatically due to organochlorine pesticides in the 1960s
Recovery since pesticide bans has been remarkable with otters now in most UK rivers
Road traffic is now the leading cause of otter mortality in the UK
Holts (dens) under river bank vegetation are vulnerable to erosion and human disturbance
Water quality and fish prey availability are key determinants of habitat quality

Welfare Considerations

Otter welfare is intrinsically linked to river habitat quality. Riverside road mortality is a significant and partly preventable welfare impact. Otter-friendly road culverts and wildlife crossings reduce collision rates substantially.

What You Can Do

Support campaigns for wildlife-friendly road design in otter habitats
Report otter sightings and road casualties to wildlife monitoring schemes
Avoid disturbing otter holts and riverside habitat during the breeding season
