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.
