“Territoriality” implies defense of an area, and many researchers create maps that help graphically illustrate the range, or territory, of a given wolf pack.

However, the area defended is not as clearly defined as a map may indicate. Territory shifts can occur seasonally or year to year.

Also notable is that neighboring territories may overlap. However, while the same area may be used by several packs, use will not occur at the same time.
