抄録

Habitat selection by Sika deer (Cervus nippon) on Kinkazan Island, northeastern Japan, was assessed by direct observation along routes tracked on foot between October 1973 and October 1977. A total of 791 deer groups (3, 237 deer) were found through 121 trackings. Around the shrine, the vegeration was dominated by the Zoysia japonica community, and the deer were tame whose density was highest (ca. 800 deer/km2) . Other deer were wild or semi-wild, and they were more frequently found in openlands than in woodlands. Selection index (S.I.) for each plant community was highest for the Pleioblastus chino community and the Zoysia japonica community, followed by the Miscanthus sinensis community, the Pteridium aguilinum community, and deciduous broad-leaved forests including the Carpinus tschonoskii community and the Fagus crenata community, and lowest for evergreen coniferous forests such as the Abies firma community, the Pinus thunbergii community, the Cryptomeria japonica community and others. Habitat selection by Sika deer on the island is primarily determined by the forage productivity of habitats, though cover requirements and innate socio-behaviorological factors are also important.
