To promote the understanding of succession process in artificial urban ecological environments, we invested the changes in bryophyte flora in an urban afforested woodland in Kyoto city. Focusing on three bryophyte functional groups (substrate preference, growth form and reproductive type), we compared the bryophyte flora in 2002 with those in 2007. A total of 41 species were recorded in 2002, and 52 species in 2007. The number of bryophyte species on trunk increased markedly compared to those of bryophyte speceis on other substrates, while bryophytes on rock showed higher turn over rate.From a view point of growth forms, bryophytes of cushion form, thread-like form, small-size appressed form and thalloid form increased greater than bryophytes of other growth forms, and bryophytes of small turf form and squamous form had a higher turn over rate. Additionally, the number of bryophyte species with asexual reproduction invaded more frequently than those of bryophyte species without asexual reproduction. These differences were explained by characteristic of bryophyte functional groups. In conclusion, to restore bryophyte vegetation in this study site based on the concept of potential natural vegetation, planting trees around the site, placing large rocks in the site and maintenance such as weeding were considered to be effective for the restoration of native bryophyte vegetation. Moreover, it was possible that introducing bryophyte species with poor dispersal ability into this site was needed for the restoration.
