Abstract |

内容記述 |
Unlike other areas in Hokkaido, the Kariba Mountain area (1,519.9 m above sea level) , located in the mountainous region bordering the western part of the Shiribeshi district and the northern part of the Hiyama district in southwestern Hokkaido, is known as the northern limit of Japan's Fagus crenata forest, predominated by deciduous broad-leaved trees. Focusing on the high-order correlation between the depth observed in a boring survey and the values obtained through AMS 14C dating, which covered elevations from low (195 m) to high (1,465 m) , and based on drilling columns and pollen and spore analysis charts, the authors examined the transition in the distribution of deciduous broad-leaved trees and coniferous trees in the forest from approximately 16000 yBP. The main tree genera in the area after 16000 yBP are Pinus, Picea, Betula, Quercus, Fagus crenata, etc. Pinus and Picea appeared as the earliest species, together with the fern Selaginella selaginoides, and persisted until around 8300 yBP. Betula, which appeared at the same time and is generally known as a pioneer species, has continued to thrive the longest without experiencing a period of decline since its first appearance. In the lower elevation areas, Quercus appeared after around 8655 yBP and has been in decline up to the present day. It was identified that Fagus crenata, which appeared in the middle to late stage (2641-1700 yBP) , has been outcompeting Quercus even to this day. |
