Otter Welfare and River Conservation

Eurasian otters have recovered significantly in UK rivers but face ongoing welfare threats from pollution, road mortality, and habitat degradation.

Key Facts

Otter populations have recovered substantially since the 1970s following pesticide bans
Road mortality is the leading cause of adult otter death in the UK
Otters require high-quality clean rivers with fish populations to meet their energy needs
Fish-eating otters are sensitive to water pollution and bioaccumulation of toxins
Otter spraints and slides are visible signs of territorial behaviour and population presence

Welfare Considerations

Otter welfare depends on river quality, fish availability, and safe passage through landscapes. Road mortality causes acute welfare harm and represents a major and growing mortality source as otter populations expand into new areas. Water quality deterioration reduces prey availability and causes chronic nutritional stress. River bank management and road crossing provisions protect individual otter welfare.
