Wild Mammal: Urban Hedgehog Population Monitoring

Urban hedgehog populations require systematic monitoring to detect trends and assess the effectiveness of conservation interventions in garden and park habitats.

Key Facts

Urban hedgehog populations are declining in some areas but may be more stable than rural populations
Footprint tunnels, camera traps, and tracking plates are non-invasive monitoring methods
Hedgehog Street programme coordinates citizen science monitoring across the UK
Individual identification through micro-chipping allows population density estimation
Monitoring data links to conservation actions including garden connectivity improvements

Welfare Considerations

Population monitoring provides the data needed to assess whether conservation interventions are improving hedgehog welfare at population level. Detecting declining trends early enables targeted action before populations become critically small. Non-invasive monitoring methods cause no welfare harm to individual hedgehogs while providing data that guides welfare-positive conservation management.

What You Can Do

Participate in Hedgehog Street's annual hedgehog survey
Install footprint tunnels or camera traps in your garden
Submit hedgehog records to the British Hedgehog Preservation Society
Join or establish a local hedgehog monitoring group
Share monitoring data with local wildlife trusts to inform conservation planning
