Dormouse Population Monitoring with Nest Tubes

Nest tube surveys are a reliable and minimally invasive method for monitoring hazel dormouse populations, enabling conservation organisations to track population trends over time.

Key Facts

Nest tubes are cylinders placed on shrubs at 1.5 m height for dormice to nest in
Tubes are checked monthly during the active season from May to October
Dormouse hair samples from tubes can be used for genetic analysis
Licensed nest tube networks cover hundreds of sites across England and Wales
Data from tube surveys informs conservation management decisions on reserves

Welfare Considerations

Nest tube monitoring exemplifies how citizen science can deliver conservation benefit while minimising direct welfare impact on animals. The method avoids live capture and provides habitat resources - dormice use the tubes as genuine nesting sites. However, the monitoring protocol requires care to avoid disturbing hibernating dormice in autumn or early spring when disturbance can be life-threatening. Survey training through the People's Trust for Endangered Species ensures volunteers handle any encountered dormice with appropriate welfare awareness.
