Dorset volunteers are being urged to take part in a survey as part of an effort to help one of Britain’s fast-declining rodents. 

Wildlife charity People’s Trust for Endangered Species (PTES) is running its annual survey for water voles in a bid to combat plunging numbers. 

Water voles underwent one of the most serious declines of any wild mammal in Britain during the 20th Century and are now on the endangered red list, but with the help of volunteers, their fate can be reversed. 

Emily Sabin, water vole officer at PTES, said: “We’re asking volunteers to find their nearest stream, ditch, river or canal, and look out for water voles, listen for their characteristic ‘plop’ as they dive into the water, or see the signs they leave behind. 

“Any sightings or signs of American mink should also be recorded.”  

“Last year, 216 sites were surveyed, with 85 showing signs of water voles.  

“This builds on 2021’s data, where 116 sites were surveyed with 47 indicating water vole presence.  

“We really hope even more people can take part this year to help us further understand how water voles are faring.”
