A report published by our partner organisation the People's Trust for Endangered Species has revealed that Britain’s native hazel dormouse (Muscardinus avellanarius) has declined by a third since the start of the 21st century.
PTES manages the National Dormouse Monitoring Programme (NDMP) - the longest-running small, terrestrial mammal monitoring project in the world. Once a familiar sight throughout much of England and Wales, over the past 100 years dormice have suffered from the loss of woodlands and hedgerows, as well as changes to farming and woodland management practices. They are also kown to be vulnerable to climatic fluctuations, in particular wetter springs and summers and warmer winter temperatures. The State of Britain’s Dormice report also finds that dormice are extinct in many English counties, although they are known to be still present in Essex.
Ian White, Dormouse Officer at PTES said: “Dormice have been around for 40 million years, but their future in Britain is now precarious and there’s a pressing need for action to ensure their long-term survival. Protecting dormice is a priority for PTES: along with the support of hundreds of volunteers, we are trying to save them before it’s too late.”
