The hazel dormouse is an elusive species, nocturnal and arboreal, so unlikely to be seen. This species typically lives in deciduous woodland, scrub and hedgerows which are well connected to the wider countryside and ancient woodland blocks. Except for hibernation, it rarely descends to the ground. Hazel dormouse populations are skewed to the south-east and south-west of Britain, and are yet to be recorded in Norfolk.

​

For projects where hazel dormouse is likely to be impacted, we provide surveys by deploying artificial nest tubes and searching for gnawed hazel nuts.

​

Timing: Nest tubes deployed in February/March. Surveys: April to November. Gnawed hazel nut searches: Mid-August to December.

We provide a full European Protected Species Mitigation Licensing (EPSML) and mitigation service for hazel dormouse, usually in combination with Landscape Design for a site. We can also supply and install dormouse nest boxes for mitigation and monitoring.
