Press release: ‘Water vole watchers’ needed to survey local waterways

Help is needed across the country to protect Britain’s fastest declining mammal, before it’s too late

Wildlife conservation charity People’s Trust for Endangered Species (PTES) is calling for volunteers in all corners of England, Scotland and Wales to survey endangered water voles, whose populations have plummeted by a staggering 90% since the 1970s.

Despite being immortalised by Ratty in The Wind in the Willows, water voles have experienced one of the most serious declines of any native wild mammal. They were once a common sight along Britain’s waterways but now, due to habitat loss, fragmentation, and predation from non-native American mink, they are listed as Endangered on the Red List for Britain’s Mammals, and need all the help we can give.

From 15th April to 15th June, volunteer ‘water vole watchers’ are being asked to visit their nearest stream, river, ditch or canal in search of water voles (or their signs) and record what they find online (ptes.org/watervoles). Tell-tale signs include feeding stations, burrows in the riverbank, latrines (piles of droppings) or listening out for their characteristic ‘plop’ as they dive into the water. There are 700 pre-selected sites that volunteers can survey, or a new site can be registered. No prior experience is needed, and free training via Zoom in April and May, and ID guides, are available online.

The results from the survey – which is part of PTES’ National Water Vole Monitoring Programme – helps conservationists find where water voles are living, how their populations are changing each year, and most importantly, where they’re no longer found. This data is crucial so that PTES can understand where water voles need the most help and implement targeted conservation efforts to help prevent further decline. Such efforts include restoring degraded rivers, improving connectivity between wetlands, and controlling the spread of non-native American mink – the water vole’s main predator.

Emily Sabin, Water Vole Officer at PTES, explains: “With their glossy dark brown fur, blunt snouts and furry tails, water voles are incredibly cute, but the decline they continue to experience is nothing short of alarming. Thankfully, in some areas water voles are starting to make a comeback due to habitat restoration work and increased mink control, but their numbers are still much lower than they should be. To prevent any further losses and to hopefully start seeing water voles across our waterways more broadly, we need as many people to take part in our survey as possible.”

Last year, an incredible 176 sites were surveyed across the country, with water voles found at 53 of them. This builds on 2022’s results where 95 sites were surveyed, with water voles spotted at 37. In 2023 eleven sites in Essex had water voles present – the highest of any county – followed closely by Norfolk where water voles were spotted at nine sites. The higher figures seen in eastern England is likely due to successful and ongoing water vole conservation work by the Waterlife Recovery Trust whose ground-breaking American mink eradication trial in East Anglia was declared a success in January 2024, with water voles finally thriving in the area.

Since the National Water Vole Monitoring Programme was established in 2015, a total of 1,174 sites have been surveyed. These include 677 pre-selected sites by PTES and 497 newly registered sites, showing that even if there isn’t a pre-selected site near to where a volunteer lives, they can still take part.

Emily adds: “Whiling away a few hours along a local waterway surveying for water voles is really enjoyable and rewarding, but it’s also a fantastic way to take part in conservation and to make a difference to the wildlife that lives around us. Over the past nine years hundreds of volunteers have taken part each year, but more help is desperately needed to fill the gaps. If you have any spare time between now and June then I’d urge to you get involved if you can.”
