Dog-guided cameras uncover weasels across Georgia, including regions unseen for 30 years
University of Georgia researchers recently located the mammal equivalent of a needle in a haystack: weasels. Weasels are extremely difficult to find, so not much is known about their preferred habitats and overall population health in the Southeast.
Researchers from the University of Georgia have discovered weasels in parts of Georgia that hadn't been seen for decades, using a combination of camera traps and detection dogs. These elusive mammals are notoriously difficult to spot, so understanding their habitat and population health has been challenging. The new study, published in Wildlife Letters, employed camera placement and detection dogs to monitor weasels across North Georgia, confirming their presence in previously unrecorded areas.
The detection dogs proved invaluable, allowing researchers to place cameras in optimal locations and boosting detection rates from 1.5% to 81%. Weasels tend to live near water sources with dense forest cover or downed logs, with activity peaking in spring and fall. The technique not only costs less than traditional methods but also provides crucial data for managing wildlife habitats and protecting these small predators.
