title: [Two types of territory used by the common shrew Sorex araneus L].
abstract: The home range of resident animals is considered as "known territory" including a "foraging region." It has been revealed that the activity of an average animal unit in the "foraging region" could be approximated by normal distribution. Estimation of activity distribution in the "known territory" (beyond the "foraging region") was impeded by means of marking since it might be difficult to detect the frequency of distant translocations, and the method does not provide an essential body of data. In the case of the common shrew Sorex araneus, the "known territory" was estimated using trap cones as animals evade them in the known areal. The "foraging region" radius of the average shrew was taken to be 30 m (95% of the animal unit activity), the radius of known territory was within the range of 180-240 m. The "foraging region" was expected to provide the animal with vital resources, and the "known territory" reflects its need for exploratory activity.
