In this study, we focused on Kansai Region in central Japan, and constructed digital point vegetation data from 1950s land-use maps in paper format. Then we overlaid it with 1980s and 2000s vegetation data in vector format and identified vegetation change patterns its distribution characteristics. As a result, the patterns of vegetation change can be classified into 66 categories, and the 12 most frequently identified patterns indicate that there are two major trends of change in the area: a) from pine trees to other vegetation and b) urbanization. In the granite-based mountain areas, especially on steep slopes, pine forests have remained since the 1950s, but in other areas, the vegetation has shifted from pine to Quercus serrata due to pine wilt disease and other factors. However, there are only a few sites where pine forests have been replaced by evergreen forests. These uneven and limited distribution of evergreen forest conversion suggests that dynamic forest change may be occurring in these areas, influenced by land use change from rural to urban areas, rather than unidirectional vegetation succession as has been discussed.
