Abstract

Research on "Vegetation Structure and Composition of Sapling and Seedling in Forest area of the Gunung Leuser National Park Village Telagah Langkat" was held in May-August 2010. The research location is determined by purposive sampling. The results were obtained INP seedling of 9765% for this type of Rubiaceae is a Nauclea sp. For INP Sapling at 10 141% for this type of family Moraceae is a Arthocarpus castaeicarpus THWALTES. On the vegetation structure by vertically seedling stratum E with number 300 ind/0.3 Ha. For vertically Sapling vegetation stratum by C with the number 233 and ind/0.6 Ha stratum D with the number 73 ind/0.6 Ha. Seedling species composition was found 73 species belonging to 17 families. Sapling species composition found 113 species belonging to 23 families. The diversity index (H ') for the seedling of 4.242, while the uniformity index (E) show the value of 0989. Diversity Index (H ') for the Sapling of 4606, while the uniformity index (E) show the value of 0975.
