If you are proposing works in suitable habitats and areas known to lie within the dormouse range, you may need a presence / likely absence survey to inform appropriate mitigation.
Dormouse nest tube surveys are the typical presence / likely absence survey and span several months between April and November. Searches for dormouse-gnawed hazel nuts are often possible in areas of fruiting hazel between August and December, but can only prove presence, not likely absence.
A derogation licence is needed from the relevant statutory body prior to any works that may impact hazel dormice or their habitats.

Our ecological consulting services
Habitat Regulations Assessment (HRA)
We can provide ecological information reports to support all stages of the Habitat Regulations Assessment (HRA) for both development projects and local plans.
Bats and their roosts are legally protected, so we recommend carrying out a Preliminary Roost Assessment (scoping bat survey) of trees, buildings and structures that proposed works may impact.
If you're proposing works in areas and habitats known to lie within the dormouse range, you may need a presence/likely absence survey to show how you’ll manage any harmful effects on this protected species.
Great Crested Newt surveys
Great crested newts and their habitats are legally protected. These creatures can travel up to 500m from their breeding ponds, so a great crested newt survey should be undertaken when water bodies are nearby.
The more widespread reptile species are legally protected. If you’re conducting work that may impact reptiles, you’ll likely need presence / likely absence and population assessment surveys.
If you’re planning works within the vicinity of a confirmed or potential badger sett or in a habitat that is suitable for badger setts to be present, it’s worth contacting us for advice.
Water Vole surveys
If you’re planning works near a watercourse, you may need a water vole survey to assess how they will be impacted. Water vole surveys can be carried out between April and October.
Ecological Clerk of Works (ECoW)
We can provide you with an Ecological Clerk of Works service, and field ecologists are on hand to help ensure that your building works stay legally compliant and wildlife habitats aren’t impacted.
