 note = {Bulletin, Rudbeckia laciniata invaded the Nopporo Natural Forest Park in the late 1990s. As of 2020, R. laciniata still grows in the park, but its distribution has not yet been investigated. In this study, the factors that influence the invasion of R. laciniata were investigated by comparing the vegetation, light environment, and number of visitors using forest paths at the distribution and nondistribution sites of the community. Mann-Whitney U test showed that the light environment had a significant effect on the distribution, but the number of visitors had no effect. The results of vegetation survey indicated that the Sasa community may inhibit the invasion of R. laciniata. These results suggest that forest paths between forest edges were a suitable environment for the invasion of R. laciniata because they provide a good light environment and prevent the growth of Sasa genus.},
