Testing a Small, Portable Remote Passive Acoustic Device to Monitor Wolves
As part of a broader trial of noninvasive methods to research wild wolves (Canis lupus) in the Superior National Forest (SNF), Minnesota, the USGS Wolf and Deer Project (Northern Prairie Wildlife Research Center) explored whether wolves could be remotely monitored using a new, inexpensive (approximately $80 USD in 2019), remotely deployable, passive acoustic recording device.
