Found a Mink in your garden? ?
Why Britain’s wild Mink are a legacy of fur farming
By the ACTAsia Compassion in Fashion team · Updated 2 November 2026. General information drawn from UK wildlife bodies and legislation. For wildlife or legal advice, contact your local wildlife trust or the relevant authority.
Wild Mink in the UK are American Mink whose ancestors escaped or were released from fur farms. They were brought to Britain for fur in the 1920s and were breeding in the wild by 1956. Mink are not protected, it is illegal to release one into the wild, and they have driven a severe decline in native Water Voles.
What is a Mink, and is it native to Britain?
The Mink you might spot along a British river, or occasionally in a garden near water, is the American Mink. It is not native. It is a small, dark brown, semi-aquatic predator with a white patch on its chin, about the size of a ferret, and it is often mistaken for an Otter or a Polecat. Some wild Mink are paler, from white to grey or fawn, a reminder of colours bred on fur farms.
Why are there Mink in the UK?
Because of fur farming. American Mink were imported into Britain in the 1920s purely to be farmed for their fur. Over the following decades, animals escaped from farms or were deliberately released, both by fur farmers hoping to produce “free-range” pelts and later by campaigners. The first wild Mink was recorded in 1948, and breeding in the wild was confirmed in 1956.
Within a few decades, Mink had spread along rivers across much of Britain. The last Mink farm in the UK closed in 2003, when fur farming bans came fully into force, but the animals they left behind are still here. Europe is now facing the same lesson: according to ACTAsia’s 2026 report, the EU listed American Mink as an invasive alien species in July 2025, which is expected to end Mink breeding there by 2027, although exemptions could let some farms in Denmark, Finland and Greece continue.
Why are wild Mink a problem for British wildlife?
Mink are skilled hunters with no natural place in British ecosystems. Their biggest impact has been on the Water Vole, the riverside mammal once familiar to every child who read The Wind in the Willows. Water Vole numbers were already falling through habitat loss, but the decline accelerated sharply once Mink spread, because a Mink is small enough to follow Water Voles into their burrows. Water Voles are now among the UK’s most endangered mammals.
Mink also take ground-nesting birds, fish, frogs and, where they can reach them, poultry. Conservation groups across the country run Mink control projects to give Water Voles a chance to recover.
Can you legally own a Mink in the UK?
American Mink are not a protected species, but they are classed as an invasive non-native species. Under Schedule 9 of the Wildlife and Countryside Act 1981, it is an offence to release a Mink into the wild or to allow one to escape, which places strict legal responsibilities on anyone keeping one. Invasive species rules may also require a licence. Check the current invasive species guidance on GOV.UK and confirm whether keeping an American mink currently needs a licence under GB invasive species rules (the Invasive Alien Species (Enforcement and Permitting) Order 2019)
What should I do if I have a Mink in my garden?
- Stay calm and keep your distance. Do not try to catch, corner or feed it.
- Bring pets indoors and keep children away until it has moved on.
- Secure chickens, ducks and rabbits in predator-proof housing with fine mesh, and shut them in at night.
- Protect garden ponds with netting if you keep fish.
- Report the sighting to your local wildlife trust or records centre, which may run a Mink project in your area.
- Do not try to trap it yourself. A trapped Mink cannot legally be released, so trapping is a job for trained people working within the law.
Will a mink go after a dog?
Mink usually avoid dogs and people, and a healthy dog is far larger than a Mink. But a cornered or frightened Mink will defend itself and can bite. Near rivers where Mink live, keep dogs under close control and call them away if they find one. If your dog is bitten, clean the wound and contact your vet.
Are Mink dangerous to humans?
Not in normal circumstances. Mink are shy and will usually flee. The risk comes from handling one or cornering it, when it may bite in self-defence. Never pick up a Mink, even one that seems injured. Call a local wildlife rescue for advice instead.
ACTAsia’s view. Neither the Water Voles nor the Mink chose this. The Mink in British rivers are the descendants of animals bred in cages for coats, and the Water Voles are paying for a fashion industry most people have long since rejected. It is a powerful reminder that the harm of fur farming does not stop at the farm gate, and that compassion has to include the wild animals caught up in our choices.
The same risks, still being farmed elsewhere
Britain closed its last Mink farm more than twenty years ago, but Mink farming has not ended. ACTAsia’s 2026 report found China produced 4.87 million Mink pelts in 2025, up 15.4% on the year before. Large-scale fur farming carries the same risks that Britain learned the hard way, plus others: a 2024 study in Nature found that farmed fur animals carry viruses with the potential to spread to humans.
ACTAsia, an Asian-founded charity registered in England and Wales (no. 1127625), works on the consumer demand that keeps those farms running, through research and its Compassion in Fashion programme, whose curriculum has reached more than 5,000 students across 95 countries. You can read the executive summary of ACTAsia’s 2026 fur trade report, and see where UK law on fur stands today. The Compassion in Fashion curriculum has reached more than 5,000 students across 95 countries, and 83% of participants agree that using fur in fashion is wrong.

Frequently asked questions
Why are there Mink in the UK?
American Mink were brought to Britain in the 1920s to be farmed for fur. Animals escaped or were released from farms, the first wild Mink was recorded in 1948, and breeding in the wild was confirmed in 1956. Their descendants now live along rivers across much of the country.
Can you legally own a Mink in the UK?
American Mink are not protected, but they are an invasive non-native species. It is an offence under the Wildlife and Countryside Act 1981 to release one or let it escape, and invasive species rules may require a licence. Check GOV.UK guidance before keeping one.
What should I do if I have a Mink in my garden?
Keep your distance, bring pets indoors, and secure poultry, rabbits and pond fish. Report the sighting to your local wildlife trust or records centre. Do not try to trap it yourself, because a trapped Mink cannot legally be released.
Will a Mink go after a dog?
Usually not. Mink tend to avoid dogs and people, but a cornered Mink will defend itself and can bite. Keep dogs under close control near rivers where Mink live, and contact your vet if your dog is bitten.
Are Mink dangerous to humans?
Rarely. Mink are shy and usually flee, but they may bite if handled or cornered. Never pick up a Mink, even one that looks injured. Contact a local wildlife rescue for advice instead.
Why are Mink bad for Water Voles?
Mink are small enough to follow Water Voles into their burrows, so they can wipe out whole colonies. Their spread sharply accelerated the Water Vole’s decline, and Water Voles are now among the UK’s most endangered mammals. Mink control projects help them recover.
Are there still Mink farms in the UK?
No. Fur farming is banned across the UK, and the last Mink farm closed in 2003. Mink farming continues elsewhere, especially in China, which produced 4.87 million Mink pelts in 2025 according to ACTAsia’s 2026 fur trade report.
Education is urgent. Behaviour is learnt. The mink in our rivers show that fashion choices can echo for generations, and that is exactly why choosing fur-free matters. Help end fur farming at its source.
