Abstract

Movements of adult female deer (Odocoileus hemionus sitkensis) were monitored using radio-collars (n = 21) in a region lacking old-growth conifer forest on Kodiak Island, Alaska, from 17 July 1990 to 8 July 1991. Mean distance between seasonal ranges for 7 deer that migrated from the study area during winter was 22 km (SD = 10.2 km), whereas < 5 km separated seasonal ranges of 14 deer that remained in the study area throughout the year. Mean movement date to winter range was 30 October (SD = 38 days), and to summer range, 29 May (SD = 18 days). Overall habitat use differed significantly (P < 0.001) between seasons. Habitats used more than available (P ≤ 0.01) were tall shrub closed in summer and tall shrub open in winter. Using the 95% adaptive kernel method (Worton 1989), mean summer home range (454 ha, n = 11, range 134 - 819 ha, SD = 227 ha) was larger (P < 0.001)than the mean winter home range (107 ha, n = 9, range 67-217 ha, SD = 56 ha).
