英文摘要: Most coppice forests in Japan were abandoned in the 1960s for socio-economic reasons. In the last two decades, Quercus crispula and Quercus serrata, the main species in Japanese coppice forests, have suffered mortality from Japanese oak wilt disease (JOW) vectored by the ambrosia beetle Platypus quercivorus. To clarify forest changes due to secondary succession and JOW in abandoned coppice forests, stand dynamics over 23-26. years in 16 permanent plots in Toyama Prefecture, central Japan, were analyzed. Seven plots were beech-oak stands dominated by Fagus crenata and Q. crispula, and nine were oak stands dominated by Q. crispula (in five plots) and/or Q. serrata (in six plots). In beech-oak stands before the appearance of JOW, dominance of shade-tolerant F. crenata increased and that of less shade-tolerant Q. crispula decreased in all seven plots, as expected from process of secondary succession. Since 2005 when the incidence of JOW became noticeable, Q. crispula suffered high mortality rates, and basal area in 2013 decreased compared with the first measurement (1987-1990) in all 12 plots. In contrast, JOW had less impact on Q. serrata because of its low mortality rates with JOW. In beech-oak stands, F. crenata expanded in dominance because of secondary succession and subsequent JOW, and stands will develop into old-growth beech forests over the long term. In oak stands, shade-tolerant canopy species under dead oak trees, such as Acer sieboldianum, are expected to replace dead oak trees, but understory species might also increase and slow the growth of saplings and seedlings of canopy tree species. Regeneration of oak was inferred to be difficult. JOW had a large negative impact on Q. crispula dynamics in abandoned coppice forests at a regional scale, and severely damaged oak stands will become heterogeneous forests composed of various species and ages, unlike the even-aged and rather monospecific oak coppice stands. © 2014 Elsevier B.V.
