Continuous removal trapping in three areas of study yielded information regarding the emigration of small mammals from peripheral areas. Two of the trap lines were operated for 80 consecutive days during the summer months of 1966 and one trap line was operated for 30 days during the winter of 1967. In 22,746 trap nights 1126 small mammals representing 14 species were captured. During the period of continuous removal trapping a continuous decline in catch did not occur. A secondary increase attributed to an emigration of animals from peripheral home ranges centered around the fourth to sixth days. A dominant-subordinate relationship was not disclosed in the sampled populations.
