Dormice Surveys across Surrey, Dorset, Somerset and Wiltshire

Dormice-Current Status and why they are protected

Common dormice and their habitats are fully protected by both the Wildlife & Countryside Act 1981 (amended) and the Conservation of Habitats and Species Regulations (2010) and are a priority species under the UK Biodiversity Action Plan. It is an offence to kill, injure, disturb or capture or destroy or obstruct their resting or breeding places.

Dormice Surveys






Developments that may impact on dormice or their habitats require an appropriate dormouse survey. A dormouse survey would usually commence with a walkover survey to search for evidence of dormice such as gnawed hazelnut shells and dormouse nests in vegetation. 

If the presence of dormice is considered likely, it will be necessary to conduct a nest tube survey to verify dormouse presence or absence from the site. Nest tubes and boxes are suspended along horizontal branches in suitable vegetation and checked at intervals between April-October for dormice and their nests. 

Surveys can take up to six months to be completed, so planning at an early stage is essential to avoid long delays in your development. Use our dormouse survey and mitigation calendar above to help plan your work schedule. Find out more from The Dormouse Conservation Handbook.

Mitigation








Ecological mitigation may be avoided if it’s possible to retain and protect areas of suitable dormouse woodland and hedgerow habitat during the development process. If damage, disturbance or removal of dormouse habitat is necessary this would need to be implemented under a European Protected Species Licence. 

Appropriate mitigation will need to be implemented at a suitable time of year and habitat clearance conducted in a sensitive manner to reduce the risk of harm to dormice. It is also essential to ensure the maintenance of habitat continuity when planning a dormouse mitigation and compensation
strategy.

Translocation of dormice to alternative off-site habitats is possible in exceptional circumstances,
but should be considered as a last resort option as it is disruptive to natural populations and the success rate of translocations is indefinite. 

Licensing






If development activities are likely to cause an offence and ecological mitigation is required for the site, a European Protected Species Licence application will be required, accompanied by a detailed method statement setting out the mitigation and compensation measures necessary under the licence. The licence application must show that the favourable conservation status of the dormouse is maintained at that there is no satisfactory alternative to the proposed development. In England, survey licences are issued by Natural England.
