Barbed wire hair traps as a tool for remotely collecting hair samples from beavers (Castor sp.)
The recolonisation of much of Europe by the Eurasian beaver (Castor fiber) entails new management, conservation and research challenges. DNA analysis can function as a powerful method in this respect. We conducted a trial to determine the effectiveness of barbed wire hair traps for remotely plucking hair from free-ranging beavers. At all sites it was possible to rapidly obtain hair samples containing guard hairs with follicles. Barbed wire hair traps can thus be employed as a cost effective way of collecting DNA from beavers without subjecting them to the stress of capture and handling.
