UK Water Shrew Conservation: Wetland Specialist

The water shrew is one of the UK's most elusive mammals, requiring clean, fish-rich streams and wetland habitats for welfare and survival.

Key Facts

Water shrews are venomous - their saliva contains toxins that paralyse invertebrate prey
They require exceptionally clean water with high invertebrate prey density
Pollution, habitat loss, and mink predation are primary welfare and conservation threats
Water shrew populations are indicators of waterway health and can be monitored through live trapping surveys

Welfare Considerations

Individual water shrew welfare depends on clean water quality, abundant invertebrate prey, and appropriate bankside vegetation. Conservation of water shrew populations requires waterway restoration and pollution reduction that benefits multiple other wetland species simultaneously.

What You Can Do

Support waterway restoration and pollution reduction projects
Engage with citizen science monitoring programmes for water shrews and other waterway wildlife
Advocate for robust water quality regulation that protects sensitive wetland species
