Our wildlife vets have given nine rare hazel dormice the all-clear, ahead of the tiny rodent’s release into the wild next month.

The dormice – including three born at Whipsnade Zoo - each received a health screening from our Disease Risk Analysis and Health Surveillance Team (DRAHS), as part of ongoing national conservation efforts to recover populations of this vulnerable mammal, which was once widespread across England and Wales.

During the 10-minute-long health checks, the fluffy-tailed dormice were placed under general anaesthetic so that the team of vets could gently check the heart and lungs of each dormouse, before carefully looking over their eyes, ears, nose, teeth and fur, to ensure the animals are ready for release. Each mouse was fitted with a microchip to help conservationists accurately identify individuals during follow-up monitoring, when they check how the dormice are doing in their new woodland home.
