The Sapporo Experimental Forest comprises the Sapporo Experimental Nursery (ca. 3.4 ha) situated at the southwestern end of the Hokkaido University campus, with the Toyohira (94 ha) and the Oshoro experimental sites (1.4 ha). The Sapporo Experimental Nursery is used for student training programs, the production of nursery stock for experiments, the production of nursery stocks for on-campus afforestation projects (including the Heisei Poplar Avenue), observation of tree phenology, research on forecasting of global warming (FACE, free air CO２ enrichment), and allelopathy tests. Attempts are being made to preserve species and genes through establishment of the Eurasian Model Forest and a rock garden. The Toyohira Test Site consists primarily of a natural regenerated, secondary, broad-leaved forest. Growth tests of ash (Fraxinus mandshurica var. japonica) and Japanese larch (Larix kaempferi) are conducted in addition to observations of forest vegetation. The Oshoro Test Site was established in 1945, and maritime forest development experiments are carried out for environmental and landscape conservation.
