Abstract
Changing vegetation which has been caused by the decline of pine forests in the Tokai district, central Japan in recent years is described based on field work. Pine forests of both Pinus densiflora and P. thunbergii distributed along the coastal area in the Tokai district have declined by the attack of Bursaphelenchus xylophilus since the 1980s. Original vegetations of the pine forests have changed to other types and flora will be expected to change. Changing vegetation and flora are examined at eight sites. From the results, establishment of evergreen broad-leaved forests dominated by Castanopsis sieboldii, and/or the deciduous forests dominated by Quercus serrata are found and an increasing in species number is recognized.
