HalpinRobbins have experienced ecologists capable of conducting a range of Dormouse surveys, each tailored to meet our clients' needs and project requirements.
Surveys are undertaken as either "stand alone" surveys or as part of Preliminary Ecological Appraisals or Ecological and Environmental Impact Assessments and the requirement to undertake a Dormouse survey is usually determined during a Phase 1 Ecology Survey.
As general guidance; if a site or project contains diverse deciduous woodland, species-rich hedgerows or dense scrub or is adjacent to such features it is likely that a Dormouse survey will be required, in some form.
Surveys start with an initial site walk over and habitat suitability assessment which includes looking for field signs of activity and presence such as nests and opened hazel nuts. The results from this determine the requirement for more detailed Dormouse survey work, such as an active search**.
Active searches can comprise a variety of suitable techniques including setting up nest tubes and boxes, in appropriate habitats, to aid in finding signs of presence and actual individuals. Due to the nature of Dormice, spending up to three quarters of the year "asleep", active search surveys must be undertaken over a long period of time to give confidence to the conclusion of the survey. This can mean that to confirm presence or absence regular site visits may be required between April and November.
Due to this lengthy process it is advisable to get Phase 1 Surveys, to determine the requirement for a Dormouse survey, underway as soon as possible for any development or conservation project.
HalpinRobbins are able to conduct habitat evaluation and nut search surveys to show Dormice use of sites and areas, these surveys can be used to inform further Dormouse survey work and potential future constraints to development and project works.
*Protection under the Wildlife and Countryside Act 1981 (as amended) and the Conservation of Habitats and Species Regulations 2010 (as amended), it is an offense to kill, injure, take, disturb or destroy individual Dormice and their breeding and resting places.
**Dormice are a European Protected Species, therefore active search Dormouse surveys should only be undertaken by a qualified and wildlife licenced individual. Wildlife licences, issued by the relevant governing body (such as Natural England, Natural Resource Wales or Scottish Natural Heritage), are required to work with the Dormouse.
More useful information about the Dormouse can be found on the Mammal Society website.
