A phytosociological survey was carried out on Quercus mongolica var. grosseserrata forest in Aomori Prefecture. Based on the floristic composition, the following single community and two associations were recognized. Quercus mongolica var. grosseserrata-Quercus dentata community is found on river-facing slopes or sea-facing slopes. Carpino-Quercetum grosseserratae is distributed only in the northern part of the peninsula. Lindero membranaceae-Quercetum mongolicae grosseserratae is distributed widely over the Tsugaru Peninsula. The floristic composition of these community units was compared with that of Quercus mongolica var. grosseserrata forests investigated by other researchers. The distribution pattern of the units is closely related to climatic conditions in winter, especially those of snow, humidity and air temperature.
