dormouse surveys

What we can do for you:

We have a number of experienced ecologists in-house who are registered and licenced by Natural England to survey for Hazel Dormice; a European protected species. Some of our staff have also centrally involved on a voluntary basis with setting up County Dormouse Groups in Southern England.


We are fully conversant with the survey and assessment guidance published by Natural England in the Dormouse Conservation Handbook (2nd Ed), and subsequent technical advice notes, and have developed our own in-house protocols for working with this species. In addition, some of our staff also have experience working with Edible Dormice; a non-native species introduced to Southern England.


Following an assessment of the potential suitability of habitat for Dormice, its interconnectivity with the surrounding landscape and a desktop search to look for records, the quickest way to investigate the potential presence of Hazel Dormice is often to search for fallen Hazel nuts in autumn, as Dormice chew in a characteristic fashion which identifies their presence.


However, where more information is needed, or where there is insufficient fruiting Hazel, it may be necessary to carry out a survey using nest tubes and boxes. Subject to the size of the survey area and the number of boxes/tubes deployed, this type of survey can take a whole season (Apr-Nov) to undertake robustly. This type of survey can also provide useful information about the distribution of Dormice across a site.


In addition to Dormouse surveying, we have a long track record of successfully designing mitigation strategies to prevent negative impacts on Dormice from development such as road schemes and residential projects, and securing Natural England European Protected Species Licences to enable proposals to proceed. We have also worked on many schemes that have successfully delivered enhancements for Dormice such as better woodland or hedgerow management.

Do you need practical professional advice on dormouse issues?


Do your plans for development include habitats such as hedgerows, woodland or scrub where dormice may be present?
