The hazel dormouse is typically found in woodland areas, hedgerows, and woody vegetation. They are susceptible to isolation via roads, meaning populations are found in pockets across the landscape.

The survey involves the deployment of dormouse tubes across the Site within hedgerows, woody vegetation and woodland. The tubes are then inspected over a period of five to six months between April and November – inclusive. The survey looks for the presence of the hazel dormouse and their evidence, including nests.

These surveys allow an accurate assessment of the ecological importance of the hazel dormouse within the Site. The survey results form the basis of the ecological decision making and associated mitigation, including detailed design and layout considerations.


One of our ecologists visits the Site five to seven times over the summer, checking for evidence of hazel dormice within artificial nesting tubes.


A number of detailed maps are produced with the results either provided in a letter style report or slotted into an Ecological Impact Assessment (EIA).
