Yorkshire Dales National Park’s Post

You guessed it, it's hazel dormice! 🐭 The wildlife team here at the Yorkshire Dales National Park Authority has wrapped up the final dormouse survey of 2024. Led by Wildlife Conservation Officer Ian Court, a dedicated team of licensed handlers and volunteers monitor the local population of hazel dormice in a woodland in Wensleydale. The dormice are monitored over a six month period between May and October, when the dormice are most active - foraging, preparing for their long winter hibernation. Ian Court, Wildlife Conservation Officer at the Yorkshire Dales National Park Authority, said: “Dormice make a nest by weaving grass together in a really tight ball, with a chamber in the middle. One of the other obvious signs that it is a dormouse nest is they like to use hazel leaves. Over winter dormice hibernate, not in the boxes but in the ground. In the spring they come out and use the boxes, as well as the coppice stools and bramble patches, for nesting and resting. They don’t need the nest boxes necessarily, but the boxes are there so we can keep the monitoring consistent. Seeing a nest in a box means that we know that dormice are still here, even if we don’t find any dormice. We are doing everything we can to manage the woodland to provide the habitat these mammals need, for example by traditional coppicing of the hazel trees to maximise nut production." A big thank you to the team involved in this important work! DISCLAIMER: Hazel dormice are an endangered species and are fully protected by law. It is an offence to disturb them (unless you are a licenced professional.) #yorkshiredales #conservation #dormice
