Visual searches seek gnawed hazel nuts within the grounds to determine the presence of dormice on a site. Nest tube surveys are also used to confirm the absence/presence of dormice in a woodland by using tubes.
When Can a Visual Searches & Nest Tube Dormouse Survey Be Undertaken?
These nest tubes should be installed in March, in preparation for the beginning of dormouse surveys, and the dormouse surveys can only be conducted between April and November when they are out of hibernation.
The nest tubes should be checked during the summer months at fortnightly intervals. Both surveys should be installed and conducted by a licensed dormouse ecologist. A score of 20 or over is needed for the survey to be considered sufficiently robust and give confidence that a false negative result has not been obtained.
