Description
Mass mortality caused by oak wilt disease is spreading in secondary forests in Japan. To understand the mechanism maintaining secondary forests in succession, it is important to clarify the age structure of such forests. Therefore, 35 Quercus serrata along a forest road in a secondary forest dominated by Q. serrata in Shimane University’s Sambe Forest, including 10 live trees and 25 trees that had died of oak wilt disease, were felled at a height of 0.3 to 0.5m and the numbers of annual rings and widths every 5 years were measured. The ages of the felled Q. serrata ranged from 51 to 75 years. Although the radial growth had peaked, large individuals maintained greater growth until felled. Relatively old Q. serrata are subject to damage from oak wilt disease. When there was no damage due to oak wilt disease, the Q. serrata in the study forest could grow more because the trees that died also kept growing before the wilt disease damaged them.
