Due to the fact that less data available about N. gracilis in that location, so that this reaserch was need to be done. The research was conducted in February 2016 with the aims to determined the population and dissemination pattern of N. gracilis in rhino camp, sukaraja atas resort, BBSNP. The data was collected by line transects which placed purposively. The results shown that there was 2079 pitcher of N. gracilis disseminated on six transects. About 60% N. gracilis covered locations plot observations with highest quantitative parameter value was situated on 3rd transect with the density (D) 11, 08 pitcher/ha, relative density (DR) 26, 67%, frequency (F) 0,150%, relative frequency (FR) 25, 08% and the lowest was on sixth transect with the density (D) 1,200 pitcher/ha, relative density (DR) 28, 9%, frequency (F) 0,041%, relative frequency (FR) 6,85. The dissemination pattern included as assembled in the altitude 615-645 meters above sea level. Keywords : Nepenthes, Population, Sukaraja Atas, BBSNP
