Background Information on Wolves

The U.S. Geological Survey Project

Following is some background information about the wolves that are radio-collared in the Superior National Forest. The work is being conducted by the Biological Resources Division of the U.S. Geological Survey. Pack sizes vary as wolves die, disperse or return from temporary excursions away from the pack. The “Date Radioed” indicates the date the wolf was first captured and had a radio collar put on. Trapping occurs in the summer. Signals of wolves are often Last when wolves disperse or make excursions away from the pack, and they may not be located on the survey for a period of time, or ever again. Occasionally wolves will switch packs.

For an example of one wolf’s story, read Case Study – Wolf 381.
