The flora of an old Quercus serrata forest reserve, with an area of 4.12 ha and located in Iwate Prefecture, northern Japan, was investigated. The forest had been undisturbed by silvicultural treatment, including weeding and cutting, for over 90 years. The objective of this study was to estimate the dynamics of the flora by comparisons with the flora recorded in 1977 and 2006. The forest had a total of 227 plant species in 2006. Compared with 1977, there were 87 species of newly colonized plants; 24 species had disappeared. Thus, the number of forest plant species had probably increased during the intervening 29 years, since the number of newly colonized plants was more than three times higher than the number of plants that had disappeared.
