Water vole appeal

Protect water voles

Water voles are at risk of extinction in Britain

Have you ever seen a water vole? If you have, you’re very lucky. They’re now our fastest declining mammal. In the 1980s and 90s, they suffered a catastrophic 90% drop in their population, largely due to the spread of American mink, which were introduced into our countryside through illegal releases or escapes from fur farms. To make things worse, a steady loss of wetlands and freshwater areas is forcing water voles to live in less-than-ideal habitats where they’re more exposed to mink and at risk of local extinctions.

You can help water voles from being wiped out. We’re helping Natural England create a strategic action plan, ready to pilot next year. You can help provide the evidence needed to support it.


Evidence from our National Water Vole Monitoring Programme will be the backbone of the action plan. It’s a crucial element in saving water voles from extinction. Each year our volunteers survey waterways across Britain, recording where water voles are found to be present or absent. It’s thanks to past monitoring like this that we know how much the water vole population has declined. Now, it can help save them.

The more evidence we gain, the more effective future water vole conservation will be, so we’re expanding our survey. We’ll run training courses to encourage more volunteers, and survey more sites. And we’ll improve the monitoring itself. Water vole signs are tell-tale but elusive, so it can be down to luck if they’re easy to spot on survey day. To increase the odds of finding them, we’re trialling the use of floating latrine rafts to see if they can help surveyors find the evidence of water vole presence more often and easily. Spotting droppings on floating rafts is a great deal easier than hunting for signs of burrows and chewed grasses. It might even identify water vole sites we weren’t aware of.

I’m sure you know how vital evidence is to conservation. It’s crucial to spotting long-term trends and helps us judge where action is needed most. I can’t stress enough how much water voles need us all working together to save them. These sweet, elusive animals deserve to be safe in our rivers and wetlands. If you can help today, you’ll be strengthening the water vole monitoring that underpins the action plan to save them. Your support now could help save water voles in Britain.

Yours sincerely,
