The pollen analysis of core samples from the Hatchodaira moor (alt. 810m) in the montane zone at the northern part of Kyoto City, revealed seven vegetational changes to have occured there during the last 25,000 years. 1. Conifer・Betula stage (ca. 25,000-15,000 y.B.P.) : subarctic coniferous forest. 2. Fagus・Lepidodalanus-Conifer・Betula stage (ca. 15,000-12,000 y.B.P.) : the ecotone between subarctic coniferous and cool temperate broad-leaved forests. 3. Conifer・Betula stage (ca. 12,000-10,000 y.B.P.) : subarctic coniferous forest. 4. Fagus・Lepidobalanus・Betula stage (ca. 10,000-9,000 y.B.P.) : the ecotone between subarctic coniferous and cool temperate broad-leaved forests. 5. Fagus・Lepidobalanus・Carpinus stage (ca. 9,000-4,500 y.B.P.) : cool temperate beech (F. crenata) forest. 6. Lepidobanlanus・Carpinus・Betula stage (ca. 4,500-1,500 y.B.P.) : cool temperate oak (Quercus mongolica var. grosseserrata) forest. 7. Pinus stage (ca. 1,500 y.B.P.-present) : pine (P. densiflora) forest reflecting the destruction of natural forests by human activities.
