Dormouse Surveys

Over the last 100 years dormice numbers and distribution across Britain have seen significant declines, primarily as a result of habitat loss. Native dormice (referred to as the Common / Hazel Dormouse) are fully protected under UK and European legislation (see our European Protected Species page for more information) and have been adopted as a priority species under the UK Biodiversity Action Plan.

Historically dormice are thought to have been confined to woodlands dominated by coppice management and hedgerows. However, as these habitats have declined dormice are increasingly found in lower quality habitats such as small copses, scrub and conifer plantations which may be more likely to be affected by development.

Natural England Licenced Dormouse Surveys

CSa staff hold dormouse survey licences from Natural England and can provide comprehensive dormouse surveys, as appropriate to different locations. Where dormouse are found to be present CSa can provide advice on mitigation and guidance through the EPS licensing process.

As with other EPS it is recommended that dormouse surveys are undertaken early on in a project to allow avoidance measures and mitigation to be designed into the scheme. Dormouse survey work is usually undertaken over several months (ideally April to November) and it is important to apply appropriate survey effort to ensure that the results can be relied upon. Mitigation work is also subject to seasonal constraints so careful consideration of this species at the outset is important.
