In 2018, members of the USGS Western Ecological Research Center (WERC) Dixon Field Station attached Global Positioning System-Global System for Mobile Communication (GPS-GSM) accelerometer transmitters to 257 geese and 300 ducks to monitor migration patterns and behavior, with the end goal of providing timely and actionable data for their project cooperators.

To evaluate the health and status of wolf populations in east-central Superior National Forest (SNF) of northeastern Minnesota, the USGS Northern Prairie Wildlife Research Center monitors their movements and population dynamics. Since 1968, researchers have used Very High Frequency (VHF) and/or Global Positioning System (GPS) radiocollars to locate and monitor individual wolves.
To facilitate the recovery of federally endangered wolves (Canis lupus), it is critical to learn as much as possible about their behavior and habitat use. The direct study of wolves is difficult, however, due to their avoidance of humans and the inaccessibility of their wilderness territories. The USGS Northern Prairie Wildlife Research Center uses Very High Frequency (VHF) and/or Global Positioning System (GPS) radio collars to locate and monitor wolves in three areas to investigate their movements, ecology, and population.
