Innovative mammal conservation

Polecats (Mustela putorius) were once a common and widespread native British carnivorous mammal that were present across England, Wales and Scotland. However, by 1915 the polecat had been eradicated from most of its former British range, remaining only in a small stronghold of mid-Wales and the English borders.
Due to a combination of factors, including legal protection under the Wildlife and Countryside Act 1981, the population is now slowly recovering and spreading across Britain. VWT monitors its recovery using National Surveys that rely on records of polecats being submitted by members of the public (also known as citizen or community scientists). This data is vital for research into this little-known species, which leaves few field signs for study by other survey methods.
VWT’s National Polecat Survey is appealing to members of the public to record the presence of polecats, and will run from 2024 until the end of 2025. This is the only dedicated national survey for polecats and is the fourth in a series of national surveys by VWT that have taken place since the 1990s.
The National Polecat Survey is supported by other organisations including The Mammal Society, local mammal groups and biological record centres from around Britain through the sharing of polecat data.
No prior experience is necessary, but you will need access to a computer or smartphone to submit your sighting. If you can, please send a photograph or video of the animal to help with our verification and recording.
If you have seen a polecat or polecat-type animal, dead or alive, please report your sighting(s) using any one of the following methods.
VWT’s ‘Report a Sighting’ form
Alternatively, you can contact us via enquiries@vwt.org.uk and share your sighting information with us.

The Mammal Society also has the Mammal Mapper App that can be used to record any mammals, including polecats. The Mammal Society has kindly offered to share the polecats records as part of our National Polecat Survey.
We are also asking people to collect hair and whisker samples from polecat carcasses. The samples will be used for research purposes to investigate polecat genetics and diet.
If you have found a dead polecat and would like to collect samples to contribute to future research, the sample collection instructions can be downloaded here.
The sample collection form can be accessed digitally through the instructions, or downloaded for printing and posting here.
Please contact us if you have any further queries:
Please only collect polecat carcasses for samples if it is safe to do so.

Polecats belong to the weasel family Mustelidae and are ancestors of the domestic ferret (Mustela furo). Like many in this family, which also includes otters, stoats, and pine martens, they have a long body with short legs.
Some key identifying features of polecats
Polecats and polecat-ferrets
Ferrets and hybrid polecat-ferrets are often kept as pets or working animals, and can escape into the wild, becoming feral. Many do not survive, but some do, and breed with wild polecats. Distinguishing between polecats and hybrid polecat-ferrets can be problematic.
If you have seen a polecat-type animal in the wild and are unsure whether it is a polecat or hybrid polecat-ferret, we would still like to hear from you.

The polecat records and sightings collected will be used to inform a report on polecat distribution and status in Britain. Anonymised records will be shared with Local Ecological Record Centres and mammal recorders. No personal information will be made public or shared with other organisations.
