The citizen science is paid attention as an effective approach to study the number of wildlife. However, it is not easy to collect participants in such survey. The objective of this study is to clarify the characterization of potential participants among climbers who took part in Hiuchisan, Nihon Raicho (Japanese rock ptarmigan) survey tour. We conducted survey against climbers and obtained 393 responds. Depending on intention of participation of the tour, we could divide target group into two groups. Then we analyze to confirm the difference of such groups. The climbers’ characteristics were depending on climbing history, knowledge of target, experience of environmental conservation activities. At the participant recruitment, it was suggested the necessity to consider characterization of climber’s profile.
