Edelweiss in Gunung Gede Pangrango National Park (GGPNP) is one of the flora that has its attraction in supporting natural climbing tourism activities. The existence of this climbing activity with various types of climbing goals, climber behavior, limited knowledge in conservation, and so on will provide opportunities for threats to the edelweiss biodiversity. The purpose of research are to know the relationship between climber’s behavior with perceptions of Edelweiss abundance, the relationship between conservation knowledge with perceptions of Edelweiss abundance, and the relationship togethereness climber’s behavior, and conservation knowledge with perceptions of Edelweiss abundance (Anaphalis javanica) in, GGPNP. The method of collecting data to obtain primary data in the field is a non-test technique (questionnaire) in the form of a questionnaire composed of several statements relating to each variable and indicators of research variables. Hypothesis test is used the regression and correlation analysis. The results showed that there was a positive and significant relationship between climber behavior (X1) and perceptions of Edelweiss abundance in GGPNP (Y) with a correlation coefficient (r) = 0.948. This relationship can be made by the equation = 47.809+0.338 X1. There is a positive and significant relationship between conservation knowledge (X2) and perceptions of edelweiss abundance (Y) with a correlation coefficient (r) = 0.957. This relationship can be made by the equation = 47.809 + 1.316 X2. There is a positive and significant relationship between climber behavior (X1) and conservation knowledge (X2) together with the perception of edelweiss abundance (Y) with a correlation coefficient (r) = 0.966. The relationship can be made the equation = 47.809 + 0.338X1 + 1.316X2. Implications that can be carried out as a follow-up to the results of this study include the need for continuous efforts to improve conservation behavior and knowledge of climbers, especially those who climb Mount Gede Pangrango.
