Research Theme
Overview of the forest: The Tomakomai Research Site is a mixed broad-leaved and conifer-leaved forest that consists of Picea jezoensis (Sieb. et Zucc.) Carr. mixed in with cool temperate broad-leaved trees such as Acer Mono, Prunus ssiori Fr. Schm., and Cercidiphyllum japonicum Sieb. et Zucc. The volcanic plain outside the City of Tomakomai contains soils that have been disturbed primarily by the eruption of Mt. Tarumae. Around that are expansive man-made forests of Larix kaempferi (Lamb.) Carr., Abies sachalinensis, etc., but there is no record that the 43.37 ha forest group which contains the research site has been cut. From summer to autumn, the forest floor is covered with Dryopteris crassirhizoma Nakai, with scattered patches of Sasa senanensis (Franch. et Savat.) Rehd. There is a relatively robust natural rejuvenation. This research was conducted jointly with members of the Graduate School of Environmental Earth Science of Hokkaido University. The department is managing the data from the seedling surveys and the 1975-1990 tree data for its original 1 ha plot.
