| Research Abstract |
The relationship between site factors and seed dispersion feature of coexistence tree species in conifer plantations was examined. Tree species of endozoochory appeared from the low elevation region to the high elevation region in a high frequency. The occurrence of anemochory type species was higher in stands with high elevation and near from natural forests. It was concluded that frugivorous bird species and Field Mouse were the major agents of seed dispersion for coexistence tree species in confer plantations in Japan.
