The purpose of this research was to analysis an association between Daun Sang and other vegetation in Resort Sei Betung, Gunung Leuser National Park. According to its conservation status, Daun Sang was including on vulnerable categories (VUD2) and its presence was limited, then the action to conserve this species in nature is very important and urgent. This species includes understorey palm, which is need to shade by other species. Purpossive sampling was used with 30 plots, sized 20 x 20 meters for Daun Sang and other vegetation at tree stage, 10 x 10 meters for other vegetation at pole stage, 5 x 5 meter for other vegetation at sapling stage and 2 x 2 meter for other vegetation at seedling stage. Analysis of vegetation was used to determine Importance Value Index, Diversity Index, Evennes Index and Richness Index. Then analysis of association was done with an interspesific association analysis, continued with Jaccard Index. The highest Importance Value Indexes for each stage of species were Aglaia edulis for seedlings and saplings, Shorea sp for poles and Shorea dealbata for trees. Diversity Index measured by Shannon Wienner Index was high (3.5-4.02), while the range of Evennes Index was 0.8-0.97 and the range of Species Richness Index was 9.04-14.43. There was an association between Daun Sang and other vegetation on seedlings and poles, which is not strong enough, and no specific association with particular species. This fact is an evidence that if there is forest disturbance, then the population of Daun Sang will be decreased.
