During ongoing investigations by an Oregon State University graduate student, the Forest Service, and California Department of Fish and Game (DFG), two additional wolverine photographs were captured this past week. A variety of hair, track and scat samples were also sent for analysis to determine if these were from a wolverine. After the initial photograph of a wolverine was taken by a remote camera on Feb. 28, 2008, in the Tahoe National Forest, researchers, biologists and volunteers intensified the search for more detections in the same general area, north of Truckee, Calif.
Dogs trained to identify wolverine scat were used to search the area. A large grid (approximately 150 square miles) with remote cameras and hair snares was established and monitored. Ground searches were made looking for wolverine tracks. Flights were conducted to detect possible radio telemetry signals from wolverines previously fitted with radio transmitters in studies in Montana.
The following link (www.dfg.ca.gov/news/news08/08022.html) contains the most recent photographs of the wolverine taken by remote camera as well as photographs of the equipment including a wolverine hair snare and camera site.
These combined efforts yielded a search of 155 miles. Approximately 50 scat and hair samples were found and sent to the Forest Service Rocky Mountain Research Stations Genetic Laboratory for analysis. Genetic information from the analysis will determine if the sample was from a wolverine and if positive, possibly the animals place of origin as well as its sex.
It has been a wonderful experience working with such an enthusiastic and dedicated crew from many different agencies, stated Katie Moriarty, Oregon State University graduate student who coordinated the investigations and took the first photo of the wolverine. Work has been extremely demanding and without the assistance of these volunteers, it would have been nearly impossible to
