Data from the Voyageurs Wolf Project:
Here is some evidence for how territorial wolves are. This map is the result of 68,000 GPS-locations from 7 wolves in different packs from this past summer. Each wolf's collar took locations every 20 min (with the exception of the northernmost pack which took locations every 4 hr starting in October) for the duration of the summer...
This detailed GPS-data is incredibly valuable for understanding pack boundaries and also for our predation research. We visited every spot these wolves spent more than 20 minutes to determine if the wolves made a kill.
suggested reading 'never cry wolf' by farley mowat, which tells a a lot about wolves and how they live.
