Dormice

Negative records are important Finding hazel dormice isn’t easy. And it’s even more difficult to prove that they’re absent from a particular patch. But dormice are protected in law. So, when new houses are built or roads expanded, the developers must ensure that any hedges, shrubby habitat or woodlands that are likely to be disturbed …

David Talbot describes his experience volunteering this summer with the Back On Our Map (BOOM), Natural England and Morecambe Bay Partnership (MBP) during the landmark release of the 1000th hazel dormouse in Britain, as part of PTES’ National Dormouse Reintroduction Programme. Getting involved in citizen science My experience as a volunteer started pre Covid-19 in …

Our nature reserve on the Isle of Wight, Briddlesford Woods, is an ancient woodland which has a rich array of woodland flora and rare invertebrates, but is best known for its unique assemblage of mammals. It provides a home for red squirrels, 9 bat species and hazel dormice. This means we have to balance the …

Dormice reintroduction June 2021 We were delighted to team up with various partners to release the 1000th hazel dormouse in Lancashire last week. Thirty animals were released into a woodland in the Arnside and Silverdale Area of Outstanding Natural Beauty (a nationally protected landscape covering parts of north Lancashire and south Cumbria). Reintroductions are crucial …

Along with our partners at Natural England, PTES collate records from over 400 dormouse monitoring sites across the UK. The NDMP now has hundreds of trained monitors regularly checking dormouse boxes throughout the year. We’re extremely grateful to all our dormouse monitors for their great contribution to dormouse conservation. How long have you been monitoring for? …

All organisms shed DNA into the environment. Sources of DNA include mucus, hair or fur, skin, urine and faeces. This environmental DNA, or eDNA, can be extracted from samples taken in the wild (usually soil or water) and used to detect different species, measure biodiversity, and even look at the abundance of different animals. It’s …

A project at Fingle Woods A woodland conservation scheme that PTES is funding in partnership with the Heritage Lottery Fund is making new discoveries about how dormice colonise recovering habitat. The project is located in Fingle Woods, a site jointly owned by the National Trust and Woodland Trust, in the north of Dartmoor in Devon. …

Hazel dormice build different nests for different purposes: hibernating, breeding or just resting. Sometimes they don’t build a nest at all. But the different types of nests they do build might help us work out how much time dormice spend in different habitats. As part of my work at Fingle Woods, owned by the Woodland …

Voles, rats, shrews, mice, and hazel dormice can be difficult to study. Their size and behaviour make them hard to find and, living predominantly in the shrub layer and being nocturnal, makes hazel dormice even more tricky. Occasionally though, these small creatures give themselves away by their vocalisations. Whilst we may hear an indistinguishable high-pitched …

You might stumble upon a slightly frazzled looking person in a tatty woolly hat and a big purple jacket held together in places by duct tape. She may well be muttering to herself as she walks, very slowly, up and down between two lines of tape. At first glance, she appears to be metal-detecting – …

Lorna Griffiths, from the Nottinghamshire Dormice Group (NDG), describes how the dormice in her county are delighting the group members. In 2016 I wrote an article for The Dormouse Monitor about the hazel dormouse releases in Nottinghamshire. Since then, the Nottinghamshire Dormouse Project, which focuses on the three reintroductions, Treswell Wood (2013), Eaton Wood (2014) …
