Dormice

House building efforts in the UK are a constant source of contention. Too many? Too few? Whatever the case, it’s undeniable that development all too often affects our wildlife and the dwindling habitats they rely on to survive. Many of our species in our nature-depleted country are impacted by infrastructure projects. Yet there are measures …

An encounter with a dormouse During a recent trip to one of our Nottinghamshire dormouse woodlands I happened to stumble upon another wild dormouse nest. It was hidden amongst a patch of bramble and rose scrub that was winding its way up a hawthorn tree, on the edge of a young coppice compartment. The nest …

Winter is a great time to assess the health of your hedges. Without their leaves, it’s easier to see the structures and little indicators that it might need a change. Winter is also a great time for hedge management, both hedgerow trimming and larger scale rejuvenation such as laying or coppicing. Winter hedgerow management Cutting …

Windsor Safari Park Hazel dormice have always been secretive creatures. Not much was known about them until Dr Pat Morris and Dr Paul Bright began studying the species in the wild to learn more about their habits. It quickly became clear that the species wasn’t doing well. As part of wider conservation plans, a new …

The woodland home Hazel dormice are well-known for their sleepy habits and are always on the look out for somewhere to snooze. We put wooden nest boxes in woodlands where they live which provides extra places for them to take a nap, as well as a useful way for us to count them regularly and …

Last summer we put out our Fingle Woods CCTV wildlife camera kits once again, to learn more about our hazel dormice. Last time we set them up, in 2018, we detected some fascinating behaviour that wouldn’t have been possible to observe using standard nest monitoring methods. We saw dormice spend time grooming their coats and …

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.
