📰 Full Story
A new Ulster Wildlife project launched in May 2026 is using lightweight GPS tags to monitor hedgehog movements across Northern Ireland to help safeguard the species.
Selected male hedgehogs are being fitted, under licence from the Northern Ireland Environment Agency, with temporary ‘backpack’ tags that stay in place for a few days before removal.
Initial tracking shows animals moving through multiple gardens in a single night and crossing busy roads — behaviour consistent with UK studies that report nightly ranges up to about 3km.
The scheme is supported by Power NI and the Department of Agriculture, Environment and Rural Affairs via the carrier bag levy.
Conservation Detection Dogs NI is training the first hedgehog-detection dog in Ireland to help locate animals and recover tags.
Ulster Wildlife aims to tag several individuals before autumn hibernation and work with Nottingham Trent University on survey design.
Data gathered will map garden use, road crossings, feeding and resting sites to inform local conservation actions such as creating ‘hedgehog highways’, wildlife corridors, reducing use of harmful pesticides and advocating for traffic calming in hotspots.
