| Research Abstract |
The distribution and the population expansion of Ailanthus altissima, an alien tree species, in Japan were clarified. This species is distributed all 47 prefectures in Japan and 29.8% of 900 meshes of one square km in Kofu basin, Yamanashi Pref. Its growing location was defined by land utilization. Mainly two genetically different lineages were suggested to be introduced to each growing area, in Japan. The little populations in Kofu basin were genetically differentiated from each other and it suggests that small number of individuals were founder of each population in Kofu basin. In Shunan-city, Yamaguchi Pref, this tree species clonally propagated less than 50 m by root sucker.
